PNI CT25PW WIFI Smart Thermostat User Manual

Smart thermostat User manual

Introduction

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:

• according to the floor sensor
• according to the built-in air sensor
• according to both sensors

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.
