Do you have a question about the TRT033N and is the answer not in the manual?
Questions and answers
Just purchased a small Flat with two thermostats not sure how to set heating on off times?
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.
