Duel-Fuel Operations
To use the EIM in dual-fuel mode, the following equipment combinations
and conguration is required.
Defrost Air Tempering Kit (67M41) will be required. The included DT1
discharge temperature probe is inserted in the furnace air outlet between
the furnace and the indoor coil to keep the furnace from overheating the
coil which would cause heat pump high pressure tripping during the defrost
cycling. The DT1 is only needed with non-communicating furnaces and is
not required for air handlers.
