Dual Fuel Kit Sequence of Operation in Heating OUTDOOR TEMPERATURE ABOVE OUTDOOR THERMOSTAT SETPOINT 2 Heat / 1 Cool When the space thermostat calls for heating and the outside temperature is above the setpoint of the outdoor thermostat, the heat pump will operate as first stage heat. If there is a call for second stage heat, or if the thermostat is placed in the emergency heat mode, the Smart Kit™ will automatically terminate the heat pump operation and start the furnace. 3 Heat / 2 Cool When the space thermostat calls for heating and the outside temperature is above the setpoint of the outdoor thermostat, the heat pump will operate as first stage heat. If there is a call for second stage heat, the second stage compressor will be energized. If there is a call for third stage heat, or if the thermostat is placed in the emergency heat mode, the Smart Kit™ will automatically terminate heat pump operation and start the furnace.
OUTDOOR TEMPERATURE BELOW OUTDOOR THERMOSTAT SETPOINT When the space thermostat calls for heating and the outside temperature is below the setpoint of the outdoor thermostat, the heat pump will be locked out and the furnace will become first stage heat. The furnace will remain first stage heat until the call is satisfied.
BLOWER CONTROL The Smart Kit™ will stop the blower anytime it switches between heat pump and furnace operation and the blower will restart at the proper speed.
DFK-DAT DEFROST CYCLE AIR TEMPERING An optional DFK-DAT discharge air thermostat can be connected to the ‘D’ and ‘D’ terminals on the Smart Kit™ board to bring on the furnace and temper the air during defrost. The sensor setpoint should be set at 90° F. IMPORTANT NOTE: Make sure that furnace control board is compatible for defrost cycle air tempering whereby Y and W can be energized at the same time.
DFK-ODT SPECIFICATIONS The DFK-ODT is a SPDT bi-metal outdoor rated thermostat. Temperature range is 0° F - 110° F with a 2° F heating and 3 F° cooling differential. The device is UL Listed and CSA Certified.
