Control two areas

The PNI CT400 intelligent thermostat has been created to offer customers extra comfort at home, in the office or in other premises, offering the possibility to monitor and control the heating system, either automatically by scheduling on time periods every day of the week, or manually, remotely, anytime and from anywhere via the Internet and the dedicated Tuya Smart smartphone application (Android / iOS). The package includes two control units (transmitter) that allow temperature control and monitoring in two separate spaces. PNI CT400 is compatible with all thermal power plants with thermostat-compatible NO relay input without potential.


Compatible with Tuya Smart app

Add the thermostat in the Tuya Smart application and you can take complete control over the heating system in the house. View the room temperature, set the desired ambient temperature, schedule daily operating hours, activate timed operation and more.


Open glass detection function

When the "open window" (OWD) detection mode is activated from the advanced settings, the system will automatically turn off the heating if there is a sudden drop in temperature (2 ° C in 15 minutes by default) and the dedicated symbol will appear on the screen. This function is useful when opening the window to ventilate, without stopping the heating. The device will return to the previous operating mode after 30 minutes, and the symbol will disappear from the screen. Any other push of a button within 30 minutes will turn off the function, bringing the system to the programmed operating mode.
