Dual zone heating systems work with a thermostat to produce different temperature levels in different areas of a house. The dual zone system uses baffling in the ductwork to open or close ducts in order to adjust heat. Using the system enables you to produce more heat in some areas of the house and less heat in others. For example, following on the principle that heat rises, you may want to reduce the upstairs temperature zone while holding the downstairs zone at a warmer level. All adjustments are made at the wall thermostat for the system.
Raise the hinged cover on the wall thermostat to expose the control panel.
Press the "Heat Run 1" or "HR 1" button to set the heating for Zone 1. The precise labeling on the thermostat may vary slightly by brand and model.
Press the up or down arrow key to set the temperature in Zone 1 to the desired level. The selection appears on the thermostat's digital display. Press the "Set" button if your model has one. Otherwise, the new setting takes effect automatically after a few seconds.
Press the timer select buttons to choose the on and off times for the Zone 1 heat cycle if your thermostat is equipped with this feature. Programming the zone to activate the heater during certain times of the day. For example, you may not want to heat downstairs rooms until 5 p.m. as people get home from work.
Press the "Heat Run 2" or "HR 2" button to set the heating for Zone 2. Again, the exact wording on the thermostat varies with the brand of equipment. Select the desired temperature and on/off times in the same way as setting the Zone 1 selections. Use the thermostat display to verify the temperature settings.
Tips & Warnings
- Dual zone thermostats typically use an LED below each zone control to blink once per second, indicating the zone is in operation. This is normal.
