Under sengs, scroll down to Defrost Sengs (advanced
passcode required).
• Allow Fan De-Ice ON: Allows the unit to heat up the coil
without the fan rotang when defrosng, so that the
ice can melt o the fan and allow it to freely spin upon
defrost compleon.
Note: This is seldom required
• Evap Temp: This changes the acve Defrosng
temperature threshold to trigger a defrost cycle. Higher
setpoint temperatures result in the acve defrost
occurring more frequently.
Note: If more frequent acve defrosng is required, increase
the “Passive Temp” setpoint also.
• Passive Temp: This changes the passive Defrosng
temperature threshold to trigger a passive defrost. A
passive defrost doesn’t run the compressor, but instead
only uses the fan to pull air across the air coil.
Warning: This seng can aect how frequently an Acve
Defrost cycle may occur.

to “Hydronic Load” to circulate water and prevent the
need to engage electric heaters for the EME during the
defrost cycle.
Note: For the EMD, since no electric heaters are equipped,
this is the only source of heat to prevent the water from
freezing during a defrost cycle.
• Load Valve Open OFF: The HW tank will be used as
a source of heat instead to prevent the water from
freezing during a defrosng cycle.
