Smart Kit<br />
Patent Pending<br />
Dual Fuel Kit Sequence of Operation<br />
Outdoor temperature above outdoor thermostat setpoint (High Balance Point)<br />
2 Heat / 1 Cool<br />
When the space thermostat calls for heating and the outside temperature is above the setpoint (High Balance Point) of<br />
the outdoor thermostat (DFK-ODT), the heat pump will operate as first stage heat. If there is a call for second stage<br />
heat, or if the thermostat is placed in the emergency heat mode, the Smart Kit will automatically de-energize ‘Y1’ and<br />
energize ‘W1’. The furnace will then be brought on and will remain on until the thermostat call is satisfied.<br />
3 Heat / 2 Cool<br />
When the space thermostat calls for heating and the outside temperature is above the setpoint (High Balance Point) of<br />
the outdoor thermostat (DFK-ODT), the heat pump will operate as first stage heat. If there is a call for second stage<br />
heat, the second stage compressor will be energized. If there is a call for auxiliary heat, or if the thermostat is placed in<br />
the emergency heat mode, the Smart Kit will automatically de-energize ‘Y1’ and ‘Y2’ to the heat pump outdoor unit<br />
and energize ‘W1’. The furnace will then be brought on and will remain on until the thermostat call is satisfied.<br />
Outdoor temperature below outdoor thermostat setpoint (Low Balance Point)<br />
When the space thermostat calls for heating and the outside temperature falls below the setpoint (Low Balance Point)<br />
of the outdoor thermostat, the heat pump will be locked out and the furnace will become first stage heat. The furnace<br />
will remain energized until the thermostat call is satisfied.<br />
Cooling Mode<br />
When the space thermostat calls for cooling, the outdoor balance point is bypassed regardless of the outdoor<br />
temperature and only the heat pump will be energized.<br />
Reversing Valve<br />
It is important that the reversing valve selector switch located on the Smart Kit be set in the proper position. For heat<br />
pumps that energize the reversing valve in the cooling mode, set the selector switch to ‘O’. For heat pumps that<br />
energize the reversing valve in the heating mode, set the selector switch to ‘B’. Heat pump thermostats should also be<br />
configured in the same manner.<br />
Blower control<br />
The Smart Kit will stop the blower anytime it switches between heat pump and furnace operation and the blower will<br />
restart at the proper speed.<br />
DFK-DAT Discharge Air Thermostat<br />
An optional DFK-DAT discharge air thermostat can be connected to the ‘D’ and ‘D’ terminals on the Smart Kit board<br />
to limit the discharge air temperature during defrost cycle. (Typically used with an oil furnace) The sensor setpoint<br />
should be set at 90° F.<br />
DFK-ODT Outdoor Thermostat Specifications<br />
The DFK-ODT Outdoor Thermostat is a SPDT bi-metal outdoor rated thermostat. Temperature range is 0° F - 100° F<br />
with a 2° F heating and 3° F cooling differential. The device is UL Listed and CSA Certified.<br />
