PNI CT25PE Smart Thermostat

Introduction

PNI CT25PE is a programmable flush-mounted thermostat for electric underfloor heating, which turns the heating system on and off according to 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 direct 230V output for electric underfloor heating systems.
