Wireless non-programmable thermostat PNI CT22 with backlit display
Code: PNI-CT22MProduct detailed description
PNI CT22 is a wireless room thermostat for boilers and central heating systems. It consists of a control unit with a display and a receiver, which communicate with each other via radio signals. The receiver is wired into the heating system, while the thermostat can be placed anywhere in the apartment or house where you want to measure the temperature as accurately as possible.
The thermostat does not have a time schedule. You set everything manually, which makes it suitable for those who want simple and straightforward control without complex menus. The backlit display shows the room temperature and the desired temperature.
How the regulation works
The built-in sensor continuously measures the surrounding temperature and compares it with the set value. When the temperature drops below the desired level, the thermostat sends a signal to the receiver to turn on the heating. Once the target temperature is reached, the system turns off automatically. The wireless connection saves wiring between the controller and the boiler, making installation quick and allowing you to place the thermostat where you spend the most time.
