The best place for the thermostat is the room where you spend the most time, in many cases the living room or kitchen. Place the thermostat about one and a half metres above the floor, not in the sun and not on an outside wall.
If your thermostat has a dead band, your installation is, as it were, 'at rest'. The thermostat only switches on when, for example, the difference deviates more than 2˚C from the set room temperature.
Most people find that the ideal room temperature is between 19 and 22 degrees Celsius.
You can adjust the temperature on your Honeywell T4M thermostat by pressing the up or down arrow buttons located on the front panel. The display will show the current set temperature, and you can increase or decrease it to your desired level.
If the display on your Honeywell T4M thermostat is not turning on, first check if the thermostat is properly connected to a power source. Make sure it is securely plugged into the wall outlet or that the batteries are correctly installed. Also, verify that the circuit breaker for your HVAC system is in the ON position.
To program a schedule on your Honeywell T4M thermostat, press the MENU button on the front panel and navigate to the schedule settings. From there, you can set different temperature settings for various times of the day or days of the week. Use the arrow buttons to adjust and confirm your desired schedule.
If your Honeywell T4M thermostat displays an error code, it indicates a specific issue with the system. Refer to the user manual for a comprehensive list of error codes and their meanings. Each code will help you identify the problem, such as a wiring issue, sensor malfunction, or connectivity problems.
To switch your Honeywell T4M thermostat from heating to cooling mode (or vice versa), locate the mode button on the front panel. Press the mode button until you reach the desired mode: HEAT, COOL, or AUTO. The AUTO mode automatically switches between heating and cooling based on the temperature you set.

Number of questions: 1I can't change the time on the thermostat - apparently, the thermostat also controls the water temperature, which is annoying.
