Zone Systems

Forced Air - Zone Dampers - WarmFlo/Electro-Mate is the answer for zone duct systems. Controlling the amount of heat energy based upon the outlet temperature removes any concern related to reduced airflow, variable back pressure on blower, etc. Order the EM-WU series with the correct furnace interface module and appropriate program chip code. We suggest using the simplest zone damper controller (all standard 4-wire stats, zone controller 4-wire output, etc.) with a basic WF-EZ3 interface. Our experience indicates using heat pump zone damper controller with heat pump stats is an overcomplication and not required with the WarmFlo controller.
