This is a programmable room thermostat. 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. it allows users to select  different temperatures in your home at different times of the day to meet particular user's needs and preferences. But thermostat to a higher temperature will not make the room heat up any faster. How quickly the room heats up depends on the design and size of the heating system. Similarly reducing the temperature setting does not affect how quickly the room cools down.
