PNI CT25PW is a programmable built-in thermostat for underfloor heating with water, which turns the heating system on and off depending on the set temperature. You can set different temperatures for different time periods and days.
The thermostat can work and display the temperature in 3 ways:
How quickly the air in the room heats up does not depend on the settings of the thermostat but on the size and the design of the heating system.
The thermostat has a non-energized relay output that sends an On/Off command to the boiler or other water heating systems.
As the product must be connected to a 230V mains supply and to heating equipment, the installation must be performed only by qualified personnel, in order to avoid irreparable damage to the product or to the heating equipment to which it is connected, defects which are not subject to warranty.
For the first configuration of the thermostat, we recommend that you call a specialist.
Note: Make sure you have your mobile phone connected to the 2.4GHz WiFi network and the GPS location enabled. For a quick setup, make sure the phone and thermostat are as close to each other as possible (1-3 m).
WARNING:
Make sure you have a 2.4 GHz wireless network available and that you have connected your phone to it. The new generation routers and phones also come equipped with a 5 GHz wireless network activated, and the devices connect automatically on this frequency. The thermostat cannot be connected to the 5 GHz wireless network because it only works on the 2.4 GHz frequency. To configure the router and the 2.4 GHz wireless network, call a specialist.
From the application, you can turn the thermostat on and off, you can change the operation mode of the thermostat (Manual, Eco, Auto) or you can set the weekly program.
