The Timeguard TRT033N thermostat does not have programmable heating on and off times. Instead, it operates by maintaining a set temperature, which can be adjusted using the +/- buttons. The thermostat will automatically turn the heating on and off as the room temperature approaches the set temperature. Additionally, the night set-back function allows the temperature to be reduced by 4°C for 1-9 hours.
