Built-in WiFi thermostat PNI CT25B in black design
Code: PNI-CT25BProduct detailed description
PNI CT25B is a recessed smart thermostat with WiFi in black design. It turns the heating system on and off via a no-voltage relay output that functions as a dry contact. You can operate it on-site or remotely via the Tuya Smart app from anywhere with an internet connection. You can thus start or stop heating, select the operating mode, choose a program, or adjust certain parameters.
The thermostat is suitable for underfloor water heating systems of any brand, water pumps, and apartment gas boilers. It can be mounted in a modular box or PNI frame.
Main Features
- local control and remote control via the Tuya Smart (Smart Life) app
- no-voltage relay output with a maximum load of 16 A (DC/AC)
- input for an additional floor sensor, available separately
- weekly program with 4 time slots per day or manual mode
- adjustable hysteresis from 0.5 °C to 5 °C
- screen brightness setting and child lock
- ABS and glass housing, black color
Operating Modes
You can create an operating schedule for each day of the week separately, always with 4 time slots. If you do not need a schedule, choose manual mode: the heating system will then try to maintain the set temperature for the full 24 hours. The thermostat also allows for hourly and daily programming.
Floor Sensor
In addition to the built-in air sensor, the thermostat has an input for an external cable sensor that measures the temperature at floor level and sends it to the central unit. The display shows the air temperature in the room by default. The floor sensor is optional and must be purchased separately. With it, the thermostat can operate in two ways: according to the air sensor or according to the floor sensor.
