Controls

• WF-DFHP1 – provides a very simple dual fuel interface between a single stage air source heat pump and a gas or oil furnace. It allows the installer to use a conventional 4-wire heat/cool thermostat to control the system as well as interface to off-peak, demand control signals from the electric provider. Internal safeties can monitor duct temperature and run time, providing automatic switch to back-up if needed. Outdoor temperature sensor provides cold weather shutdown of the heat pump.
• WF-DHKIT – converts any electric furnace or air handler electric heat kit into a WarmFlo® controlled system. Simple connections provided for conventional 4-wire thermostat, single stage heat pump, and remote utility control signal. Internal safeties can monitor duct temperature and run time, providing automatic switch to back-up if needed. Outdoor temperature sensor provides cold weather shutdown of the heat pump.
