A room thermostat 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. So, a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs. Turning a programmable 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 programmable room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy.
The THR872CUK Wireless Programmable Thermostat is a wireless version of THR870 programmable thermostat. Programmable thermostats provide automatic time and temperature control of domestic heating or cooling systems. They have been designed for households with different heating needs for various times of the day and different days of the week to maximize energy efficiency. A mains powered relay box is installed by the boiler..
