Smart thermostat PNI CT440 wireless, with WiFi, control 4 zones via the Internet, for heating plants, pumps, solenoid valves, TuyaSmart APP

4-zone control + separate heating/cooling system control

The PNI CT440 smart thermostat was created to offer customers added comfort at home, in the office or in other premises, offering the possibility of monitoring and controlling the heating/cooling system, either automatically by programming 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 four control units (transmitter with screen) that allow temperature control and monitoring in 4 distinct spaces. PNI CT440 can control as follows:

- 4 pumping groups / pumps / solenoid valves using the 4 dedicated 230V AC outputs;

- any central heating / heating/cooling system equipped with a thermostat input compatible with a potential-free NO relay (dry contact);

Compatible with Tuya Smart app

Add the thermostat to the Tuya Smart app and you can take complete control of your home's heating/cooling system. View the room temperature, set the desired ambient temperature, schedule daily operating times, activate timer operation, and more.

Open window detection function

When the “open window” detection mode (OWD) is activated from the advanced settings, the system will automatically stop heating if a sudden temperature drop is registered (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 button press within the 30 minute period will stop the function, bringing the system to the programmed operating mode.

Daily programming for 4 time periods

For maximum convenience, you can program 4 time periods every day from Monday to Sunday. This way, you can have different programs each day, depending on the time you leave or arrive home.
Example of 4 time periods in one day:
06:00 - 23 degrees
08:00 - 22 degrees
5:00 PM - 23 degrees
11:00 PM - 21 degrees

The function is available both from the thermostat and from the dedicated application on your mobile phone.
