VisionPRO IAQ

The VisionPRO IAQ has a feature in the installation menu, menu # 346,that is a “Duel Fuel Heat Pump Upstage to Furnace Timer”.  This feature allows you to enter a time from 30 minutes to 75 minutes that you want the heat pump to run before brining on the auxiliary heat.  This feature is only available when you choose Fossil fuel back up in choice #200 and thermostat controls backup heat choice # 210.
This means that we will not have the option to time the upstage from the heat pump to the furnace when using our zone boards in dual fuel applications.
