How to Choose the Best Thermostat for a Heat Pump:

Let’s take a closer look at the factors you need to consider while shopping for a heat pump thermostat.

1. Compatibility:

Compatibility is the primary factor to consider when choosing a thermostat for your heat pump. As it ensures that the thermostat will work properly with your heat pump. Remember that not all thermostats are compatible with HVAC systems with a heat pump. So, it is essential to intently check the specification of the thermostat model before making its purchase.

2. Installation and Wiring:

The wiring needed for a heat pump is quite different from other HVAC systems. So, a thermostat you chose must support the heat pump wiring. How do we understand whether the thermostat wiring will support the HVAC system/heat pump or not? For this, you have to seek out the manufacturer’s specifications or simply check the model number online. Thus, it will give an idea of whether it is recommended for the heat pump system or not. Taking a photo of existing wire labels while replacing an old one will evade confusion. While installing a new one, you should follow the installation manual to understand the instructions and install them easily. Still getting confusion on its installation, then simply hire a technician.

3. Emergency Heating in Heat Pump:

Is the heat pump owns an emergency or auxiliary heat option? If it owns, then you won’t have any choice other than selecting a thermostat model supporting the heat pump. Generally, we find various thermostats that work well with a heat pump, yet are not suited with an emergency or auxiliary heat system. It is essential to choose a thermostat that effectively supports heat pumps with aux. heat. This type of selection is applicable only when the heat pump is compatible with the auxiliary heat.

4. Wi-Fi Accessibility:

Most heat pump thermostat models feature Wi-Fi accessibility or wireless access that let you connect to your workplace network. You can easily use them via mobile app, voice command or third-party control to run the heat pump. You can even program every feature with this Wi-Fi option without touching the thermostat manually. So, prefer to purchase a wireless-enabled thermostat for controlling these thermostat units.

5. Design and Aesthetics:

One has to choose an aesthetically designed thermostat having styling sleek, controls, and faceplate designs. It should match with your office or home décor. A few thermostat models are not at all aesthetically pleasing with their square block on the wall which won’t light up. So, pick a thermostat with really good designs.

6. Auxiliary Power Supply:

However, it is a bit challenging for the heat pump while trying to reach the selected temperature in extremely cold weather. If the air-source heat pump (primary heating mode) fails to meet the heating requirements or temperature settings, then the thermostat turns on a secondary heating method automatically, which uses an auxiliary or electric heat strip. If you need instant heating in the home, then choose a secondary heating mode as the primary mode. But remember that it consumes more electricity and thereby costs you a lot in the bill, and disables the primary heat pump as well.

7. Programmability:

The electric and smart heat pump thermostats are programmed that make your life easy to use. If you are interested in it, then avoid the mechanical ones. This programmable model will adjust the temperature according to the day of the week or the time of the day.

8. Connectivity Options:

A lot of options mentioned in this article are smart ones that let you use them along with your smartphone. But to ensure this, you have to check the connectivity options offered by the model that you are purchasing. While high-end options come with both Wi-Fi and Bluetooth connectivity, others might have just buttons and display on the unit itself.

9. Types:

The thermostat for your heat pump comes in three variants – mechanical, electrical, and smart. Each one has its set of pros and cons. Knowing them in detail will help in your decision process.

Mechanical (or) Non-Programmable Thermostat – 

Mechanical thermostats are a standard, and less expensive type of thermostat, in which there isn’t a lot of functionality. After connecting to wiring and selecting the operation mode, which is either heat only, cool and heat (or) cool, heat and fan. You have to manually operate the thermostat on/off. Initially, turn it on and slide a temperature selector or a dial to the desired temperature range. Then the thermostat will turn on the system continuously and off to keep the house at the desired temperature.

Electronic (or) Programmable Thermostat – 

Electronic thermostats are a better version than mechanical models, as they come with a digital display (with or without a touch screen) and some extra features. It let you use them as a mechanical thermostat (set the mode or temperature and turn on/off) or program them as well. They use the time and date that you set as a base for programming. Simply scroll through the days, and hour ranges in those days to set a schedule. Within the scheduled times, the electronic thermostat turns on/off the system to maintain the set temperature. Also, program these thermostats to turn off when you are not there at home and turn on when you come home.

Smart Thermostat – 

A few premium models offer extra features like geofencing that activate or disable the system when you enter or go away a set radius of the home. Also, you can program the system to turn off all day while you are at work (no one in the home) and gets turn on when you come within 2 miles of the driveway. Even though these smart models are most expensive compared to manual or electronic models, yet they offer high energy efficiency and the best control over the device.

Verdict:

Mechanical thermostat won’t have functionality, in which you have to set the temperature and turn on/off the device. Electric thermostat lets you program the time and date schedules, and has automatic or manual switching. Smart thermostat is connected wirelessly to your mobile or smart home devices. Thus, it let you schedule, program, and operate the thermostat anywhere via its app.

10. Number of Cooling and Heating Stages:

Use staging to increase the efficiency of HVAC systems, as staging will allow the system to achieve the chosen temperature progressively. So, to grab the maximum benefit from these systems, opt for a thermostat supporting most stages. However, most thermostats support one cooling and one heating operation and labeled as 1H/1C – one cooling stage and one heating stage support (on/off). Most brands provide multistage thermostats to support more than just a cooling and heating stage. Yet also use secondary methods, look for an effective thermostat with a greater number of cooling and heating stages, such as 2H/2C, 3H/3C, etc.

11. Support for Heating and Cooling:

Usually, heat pump thermostats are programmed for managing both cooling and heating on the same system. Here refrigeration process is used by the heat pump for cooling and heating purposes. With its reversing valve, a heat pump will facilitate heating to cooling and cooling to heating. This valve is energized by using 24-volts for the cooling cycle.

12. Price:

One should set the budget range and select the right one among several models in the market. However, the price range is affordable that depends on their types, and various features they offer. The mechanical thermostats cost a few bucks, and smart thermostats cost you hundreds, while electric thermostats fall in between the price range of these two types. If the budget is low, you can go with a simple programmable thermostat for the heat pump, which is enough to provide efficient performance. Also, it provides adjustable temperature at your convenience.

13. Warranty:

One has to check the warranty period offered by the manufacturer before making the product purchase. Most thermostat models come with a minimum of a 1-year warranty, while a few models offer a 2 years, 3 years, or 5 years long warranty. Prefer to buy a heat pump thermostat that offers long term warranty, and also check its brand, build quality, and customer service offered by the manufacturer.

Some Key Features to Seek Out for Smart Thermostat:

Based on the technology, smart thermostats are quite different and need to consider a few factors specially than other two types. Here are those factors.

1. Programmable:

2. Geo-Fencing:

It will save a lot of energy with its away and home modes. It can be operated with a smartphone app that let you fix an imaginary fence all over the home. If you cross the line, a thermostat turns off/on as programmed. Thus, you can get into the home in a comfortable atmosphere and also prevent cooling or heating an empty home.

3. Safeguard Equipment:

Most often and unusual switching on/off of the HVAC system results due to short-cycling. However, the system won’t have sufficient time to switch on/off, which causes damage to the system. These smart thermostats can delay providing proper time for the system to shut down or start up completely to prevent this condition. Thus, it keeps the equipment safe from damages.

4. Remote Control:

One can easily control the thermostat operations with a remote without any need to accomplish them manually. Also, it let you change the settings anytime and from anywhere, and the smartphone app allows you to manage and control the thermostat settings, like creating schedules, switching the thermostat on/off, changing temperature preference, and so on. One can download the app easily for Android or iOS smartphones.

Benefits of Using Heat Pump Thermostat:

The advanced thermostat offers several benefits, which makes it essential to purchase and use it at home. Here are some of the benefits mentioned that let you know why do we use a thermostat for your heat pump.

Thereby it won’t let you suffer from several respiratory problems like asthma or allergies. Precise, Controlled Temperature – Usually, programmable thermostats (+/-1° deviation about temperature) are more accurate than analog thermostats (+/-5° variance). However, analog ones consume more energy and raise your power bill. So, it’s better to replace an analog thermostat with the programmed thermostat. Lockable Setting – Few thermostat models feature lockable settings of temperature that let you lock the temperature level. Thus, you get precise control over the thermostat and won’t let anyone unexpectedly change the temperature. Enhance the Home’s Efficiency – A perfect thermostat will allow the home to be more efficient throughout any season. Thus, it lets your appliances to last longer by utilizing your resources efficiently. So, they control the temperature and make you live relaxed and comfortably.

How does this Heat Pump Thermostat Work?

A heat pump thermostat is meant to measure and maintain the appropriate indoor temperature, especially in the cold season. Initially, you have to connect the thermostat to the HVAC system by proper wiring. Most thermostats are programmable, in which you can set the schedule, and it works best for the rest. A few premium models get switched off when no one is there to save energy (energy-efficient) and consumes less power. Moreover, it features a mobile app that makes it compatible with almost all iOS and Android devices. This mobile app will let you get complete control over the thermostat from anywhere, including the beach, office or camps. Based on the input criteria (like present temperature, time or geofencing), the thermostat will turn on/off the heat pump. While living in sub-freezing winter climates, the temperature where most of the heat pumps feature auxiliary or emergency heating functions, then use a thermostat with heating mode. Set the appropriate temperature when the temperature is fallen from programmed targets, then the thermostat will switch on the pump, and after the temperature is reached, it turns off the heat pump/HVAC system. However, the thermostat sends an electric signal to the heat pump, and the switching is triggered by specific times or schedules of the day. So, keep in mind that the thermostat will work with specific types of heat pumps before buying your best thermostat for the heat pump.

Tips to Use Thermostat:

Here are some tips that let you know how to grab the most benefits from the thermostat while using it for a heat pump.

A few models need professional assistance for their installation. Irrespective of the type of heat pump thermostat, here is the detailed installation procedure for most thermostats.

Initially, turn off the breaker that controls the heat pump and any connected devices. Take away the faceplate of the existing thermostat and clean any debris or dust for a clear vision of wires. Take a photo (or) label the wires to note down the colors and where they are connected. Then remove the wires from your old thermostat and take out the base plate from the wall as well. If you are looking to paint or repair the drywall, then you can do it now. Then run wires through the back of the new wall plate and secure it to the wall. It’s time to use the photos or labels set earlier for connecting the wires properly to the terminals in the new thermostat model. However, the excess wire should be driven back into the wall and then attach a new faceplate. Flip the breakers back on to restore the power for the thermostat. The thermostat will light up as an indication that it is connected properly and the setup sequence will begin (for smart or electronic thermostat). Turn on the thermostat to ensure everything works well. Test it once before you make it use regularly.

Understanding Heat Pump Thermostat Wiring:

A heat pump usually works as a heater and air conditioner that offer you comfortable year-round, irrespective of the season. They use a refrigeration process to provide two-way climate control (heating and cooling). An HVAC thermostat comes with 4 wires – call cool, call heat, power and fan along with AC wire. While heat pump thermostats come with a wire for calls to cool/heat, one for auxiliary heat and a couple of extra wires to install. You can use the changeover wire/reversing wire to control any changes in reversing valve that switches from heat to cool. The emergency heat wire gets deactivates the primary heat pump will ensure the secondary heat source takes over. It is used in an emergency like if you have any problem with this heat pump.
