Answer :

To stop the auxiliary heat from coming on a Honeywell thermostat, you can follow these steps:

Step 1: Check the current settings of the thermostat to ensure that it is not already set to use auxiliary heat. Look for the settings related to the thermostat's heating system and make sure that the "emergency" or "auxiliary" heat option is not turned on.

Step 2: Adjust the temperature settings. If the thermostat is set to a temperature that is too high, the auxiliary heat may automatically come on. Try lowering the temperature to see if that resolves the issue.

Step 3: Check the thermostat wiring. Make sure that the wires are connected properly and that there are no loose connections or damaged wires. If there is an issue with the wiring, this could cause the thermostat to activate the auxiliary heat unnecessarily.

Step 4: Check the air filter. If the air filter is dirty or clogged, it can restrict airflow and cause the system to activate the auxiliary heat. Replace the air filter if it is dirty to see if that resolves the issue.

Step 5: Check the system's outdoor unit. If the outdoor unit is dirty or blocked by debris, it can cause the system to activate the auxiliary heat. Clean the outdoor unit and remove any debris to see if that resolves the issue. If these steps do not resolve the issue, it may be necessary to call a professional HVAC technician to diagnose and repair the problem.

To stop the auxiliary heat from engaging on a Honeywell thermostat, install a programmable thermostat to minimize operation when not needed, adjust seasonal settings, understand the On-Off controller function, and utilize programmable alarms and set points to manage temperature effectively.

To stop auxiliary heat from coming on a Honeywell thermostat, you may need to adjust the thermostat settings. First, consider installing a programmable thermostat if you haven't already. These thermostats can be set to reduce the operation of the heater or air conditioner when it's not needed, such as when you're away from home or during certain times of the day. By programming the thermostat to use less energy, you can prevent the auxiliary heat from turning on unnecessarily.

Additionally, reducing heating and cooling energy use can be achieved by adjusting the thermostat settings seasonally. Increase the settings in the summer and reduce them in the winter to maintain comfort without over reliance on the auxiliary heat.

Understanding how thermostat controllers work can also help. An On-Off controller activates the heating mechanism when the temperature falls below the setpoint and turns it off when the temperature exceeds the set level. Adjusting the setpoint to a level that prevents frequent triggering of the auxiliary heat can avoid its unnecessary use.

Remember that the operation of your thermostat is not a totally closed system. It may be affected by external factors, such as how often the doors to the home are opened. However, proper programming can still effectively manage heating needs without overusing the auxiliary heat, which kicks in when the system detects a significant temperature difference that the regular heat pump cannot quickly reconcile.

Some thermostats also have features to program alarms to alert you when temperatures exceed critical set points, allowing for manual intervention before auxiliary heat is activated. These settings help to ensure that the temperature reaches 25°C, for example, before switching off the heating unit. Utilizing these alarms and setpoints can help manage the system more effectively.
