## Overview

The Homexpert Heating Controls THR840DUK Digital Remote Thermostat is a sleek, easy-to-install device designed to optimize your heating system. With energy-saving features and a one-year guarantee, it ensures comfort and efficiency in your home.

## Description

Product Description          Heating and hot water use 84% of energy in a traditional home (source BERR UK). This is 28 times greater than the average electricity consumption used to light your house. Just as you would turn a light out when leaving a room, small changes to the way you heat your house can bring dramatic savings to your utility bills and significantly reduce your energy consumption. The homexpert by Honeywell range of heating controls is designed to reduce waste, reduce demand and use fuel more sparingly.  What is a thermostat? A thermostat switches the heating system on and off as necessary. It works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached. Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system, for example, the size of boiler and radiators.Neither does the setting affect how quickly the room cools down. Turning a room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy. The heating system will not work if a time switch or programmer has switched it off. The THR840DUK is a digital room thermostat that is more accurate than a mechanical room thermostat. Measurements from an electronic sensor are compared with your desired temperature and advanced control software is used to maintain the temperature in an energy efficient manner. It features System Control to manage domestic heating and cooling functions within a 5ºC to 35ºC set point range. It’s easy to use as it has an extra large LCD display screen. Precise Temperature Control ensures maximum comfort by keeping the temperature to within 0.5 degrees and the ECO button provides timed temperature setback to reduce energy demand. TPI (Time Proportional & Integral) control makes boilers operate more efficiently and provides close accurate control. It also has a self learning adaptive capability. The THR840DUK is easy to install with easily accessible wiring terminals and an installation guide included and its ideal for Combi boiliers             Box Contains          1 x Homexpert Heating Controls THR840DUK Digital Remote Thermostat2 x AA batteries1 x Instruction manual
