Dual Fuel Changeover on Outdoor Temp (setup step 60) - ON: the change
from Heat Pump to a fossil fuel source of heat will be based on outdoor
temperature. (a local outdoor sensor is required for ‘ON’)
OFF: Heat Pump heating will be terminated when there is a demand for third
stage heat and a switch to fossil fuel will be made.
Dual Fuel Balance Point (setup step 61) - (0˚ - 60˚ ) Specifies the outdoor
temperature at which the heat pump will cease operating and a fossil fuel
source of heat is used.
Dual Fuel Changeover Delay (setup step 62) - (0 - 90) Specifies the number of
seconds the heat pump is allowed to continue running after a fossil fuel heat
source has been engaged.
