How to connect a temperature controller to an infrared heater?
We will not go into the types and types of regulators, arrange comparisons and tournaments. All of them are good in their own way and will fulfill their purpose, serving faithfully. The first thing you want to pay attention to is the installation location. It doesn’t depend on what type of heaters you have: infrared, panel, warm floorconvection.
The installation of a temperature controller with an air temperature sensor is prohibited in the following places:
- in the immediate vicinity of heaters;
- in places where there is a draft;
- in the heating zone of infrared emitters.
All these places are unsuitable for placing the thermostat, since when located near the heater, the air next to it will heat up to the desired temperature earlier, which will lead to a false alarm, as a result of which the room will not heat up to a comfortable temperature.
If you install a thermostat in the heating zone of the IR heater, its body will heat up earlier and distort the sensor readings. In places where there is a draft, the sensor will not show the desired temperature and the heaters will overheat the room, consuming excess electricity. The placement of the temperature sensor in height should be carried out in the comfort zone, at the level of 1.5 meters from the floor.
Always, before installing and connecting the thermostat, familiarize yourself with the instructions and passport data on the device. Since the manufacturer indicates the required cable cross-section and gives a connection diagram for its products. If you deviate from the requirements and save on wire and thermostats, there is a high probability of equipment failure or fire hazard.
To connect the heaters, it is usually recommended to use a three-wire PVA wire 2.5 mm. It is recommended to connect the thermostat with the same wire.
Connection diagram of the temperature controller to an infrared heater up to 3.5 kW:
If the room is heated by a group of heaters up to 3.5 kW, then the connection diagram will look like this:
In the event that you are the owner of a three-phase network and heating is carried out by a group of heaters with a total power of more than 3.5 kW, then a magnetic starter, which is controlled by a temperature controller, is added to the control circuit:
Here on this principle the temperature controller is installed.As you can see, there are some features in the installation and connection of the thermostat, so it is important to familiarize yourself with the instructions from the manufacturer initially, and then proceed to the main process.
Finally, we recommend watching a video in which the connection technology of the contacts is illustrated by the example of a fairly popular temperature controller from Ballu BMT-1:
