Installer Setup
Dual Fuel Changeover Delay (Setup Step 54) - (0 - 90) Specifies the number of
seconds the heat pump is allowed to continue running after a fossil fuel heat source
has been engaged.
Dual Fuel Changeover on Outdoor Temp (Setup Step 52) - ON, the change from Heat
Pump to a fossil fuel source of heat will be based on outdoor temperature. OFF, Heat
Pump heating will be terminated when there is a demand for third stage heat.
Dual Fuel Balance Point (Setup Step 53) - (5 - 60 ) Specifies the outdoor temperature
at which the heat pump will cease operating and a fossil fuel source of heat is used.
Dual Fuel (Cont.)
NONE - Scrolling display shows ‘FAULT’ when a fault signal is active.
Dual Fuel Safety Timer (Setup Step 51) - On/Off When this feature is set to ON, the
room temperature must rise 1 degree within 60 minutes after a switch to fossil fuel has
been made. If the room temperature does not rise, the fossil fuel system will cease
operating and the heat pump will be restarted.
Setup steps 51-54 will only appear if step 50 is set to ON.
