How does a thermostat work?
A thermostat controls the temperature in your home. Before we explain how smart thermostats work, let's take a look at the thermostat basics.
Thermostats work in two ways. Mechanical thermostats rely on the expansion of metal strips as the temperature rises and falls. As the metal expands under heat, it completes an electrical circuit that then activates your home cooling system. Similarly, when your heating strip cools, contracts, and activates a different circuit, your home heater turns on.
Digital thermostats operate under a similar mechanism. Although metals physically expand with heat, they also reduce their ability to conduct electricity. Digital thermostats can accurately measure conductivity changes with a special resistor and then activate or shut down your home climate system accordingly.
What makes a thermostat smart?
Smart thermostats communicate with your home heating and cooling system. Common features include remote control for smartphone apps, Internet connectivity to adjust the weather, and hands-free activation for compatible voice assistants. Over time, smart thermostats can learn the best times to heat and cool, which can save electricity when overused and ultimately save a homeowner a monthly bill. For example, E-Top's HT series thermostat with OWD function has helped customers save 27% of their electricity bills on average
How do smart thermometers work?
These additional features require some additional hardware built into the thermostat. Smart thermostats need memory to store more information and antennas to communicate wirelessly. This hardware will tend to be installed on a unified motherboard, similar to a desktop computer.
Smart thermostats usually require an ordinary wire to power the wall because they have many functions active in the background. The device also comes with backup batteries in case of a power outage or pre-installation, and most products on the market can be remotely controlled by a phone.
What are the disadvantages of a smart thermostat?
The downsides of smart thermostats are few and far between. In the past, this cost was a significant barrier to entry,But now there are a large number of cost-effective products for customers to choose from in China.For example, the temperature controller produced by E-Top has been popular in the European market for more than ten years with its high cost performance. The biggest challenge is the need to change the fixed mindset and regional prejudices of the majority of the population.

Over the years, heat pumps have attracted much attention due to the duality of their core functions. In the winter, heat pumps work like heaters, taking care of your heating and hot water needs, while in the summer, they can turn into air conditioning units. This two-in-one heating and cooling function is not commonly found in conventional boilers and heating systems, making air and ground source heat pumps all-rounders. Because of their specialized heating and cooling capabilities, heat pumps require a custom thermostat to work effectively. Thermostat technology has evolved significantly over the years, giving you energy-saving options that can be paired with a heat pump installation for superior heating performance.
Thermostats for Heat Pump – How They Work!
Thermostats for heat pumps have one simple job to do – they switch the heat pump on or off as per the predefined input criteria, like the current room temperature, time of day and other smart home features.
Its basic function is based on temperature. When the temperature indoors falls below the set number, the thermostat will turn the heat pump on. The heat pump is switched off once the set temperature is reached and your home is heated to suit you.
Thermostat settings can work around specific times of day or by a predefined schedule depending on whether you are home or not.
Types of Thermostat
There are three types of thermostat which differ in the way they perform. These are mechanical room thermostat, electrical thermostat and smart thermostat.
The least expensive is the mechanical thermostat, as there’s no defined functionality as such. You key in the temperature as per your preference and turn it on or off. Electric thermostats, on the other hand, can be programmed with details like date and time and whether you’d prefer manual or automatic functioning.
Smart thermostats can do everything that its electrical counterpart can do and on top of that, it connects wirelessly to your mobile phone or any smart home device. You can use an app to program, operate and schedule your smart thermostat from virtually anywhere.
Compatibility
Thermostats are not universal in their operation as they might not work with all types of HVAC units. This is why you have to be sure that the thermostat model you choose is compatible with the heat pump installed in your home. If your thermostat is compatible, it can replace most other thermostats as it operates your heat pump, air handler, AC, fans and ventilation. Some models are designed to control humidifiers and dehumidifiers as well.
Programmability
Smart and electric thermostats are programmable. If you wish to set up custom functions for your thermostat, mechanical thermostats are probably not for you. Based on the time of day or day of the week, you can program the settings and set temperature as per your convenience and requirements. Your thermostat will only switch on once the required room temperature is reached and only between the pre-scheduled timings.
WiFi Accessibility
WiFi accessibility is only possible in smart thermostats. To operate your heat pump at peak efficiency, you can connect to your home network using mobile apps, voice commands or third party controls. Using smart technology, you could teach your thermostat to learn and identify your habits as it begins to operate the heat pump on its own without any input required from you.
The heat pump drives the compressor for heating and cooling. Your heating and air conditioning system is revitalized by connecting a heat pump to an internal heating band. The thermostat controls the full operation of the heat pump system installed with the optional heating tape.
The thermostat manufacturer's algorithms indicate the optimal times and intervals for the heat pump, possible heating levels for your model, the heating rod, and the speed of the indoor fan. The control parameters for your system can be found in the Thermostat Configuration menu, accessed through the switches defined by each thermostat model. Information on the parameters can be found in the heat pump's installation instructions and the heating tape.
Things You Will Need to Wire a Heat Pump Thermostat

Plastic Cable Ties
Variants for Connecting a Heat Pump Thermostat
Heat pumps move the heat from one place to another. The switch between heating and cooling depends on the season and the thermostat setting. Besides, the air source heat pumps have backup heating methods for two reasons.
When the heat pump system starts defrosting, it needs a backup heat source.
The main method of backup or backup heating for heat pumps is electrical tape heaters. The second most common reserve heat source is a gas oven. Finally, these two different methods may require a separate connection of the heat pump thermostat.
Heat Pump Wire Labels
Name and connection of cable C - old cable C? This is a common thread that has caused indigestion and sleepless nights in many people. The reason for this is that most modern thermostats need or need a C-wire to work. The usual 24 V C cable comes from the control transformer and the above-mentioned R cable. Four-wire HVAC system control transformer. One side is also for the mains voltage in the transformer, and the other side is the 24 V control voltage that comes from the other side of the transformer.
Designation and connection of cable R - Cable R is the 24 V hot cable of the 24 V control transformer. This is the way to enable control relays and connections in your system. The thermostat is just a switch, and the power from the transformer comes through this device.
The Wiring Problem C
The C-wire is generally dark blue in color.
This means that if you don't have the correct amount of wire in the thermostat, you will need to connect the new thermostat wire to the new thermostat. In other words, you have the right number of conductors for your new thermostat to work properly. A heat pump thermostat requires more connections than an air conditioning thermostat. This also provides the C-wire.
