nent. Name can be up to 29 characters. Name can

HP Heating
Lockout
Time
The HP could not get a zone to progress 0.5 de-
grees towards the set point in 120 minutes (Alert
Code 40 - Minor alert). System will switch to sec-
ondary heat source. (Electric heat or furnace in
dual fuel applications). Transition back to Heat
Pump normal operation when termination setting
times out.
Range is 60 to 240 minutes. Default is 120 min-
utes. Adjustments are in increments of 30 min-
utes.
Zone 1
through 4
Continuous
Blower
CFM
Minimum and maximum CFM will be dependent
on system component congurations. These pa-
rameter values are automatically adjusted to the
specic hardware conguration. See iHarmony
zoning system installation instruction for minimum
CFMs for specic indoor units.
Zones requesting the fan ON are only allowed
while no other zone demand is present. The ther-
mostat will sum all the zone continuous blower
CFM requirements and send the command only
after positioning the dampers and waiting for the
damper close delay period to expire (30 seconds)
Continuous blower demands are the lowest prior-
ity demands, all other conditioning demands will
over-ride the continuous blower demand.
Range is 5 CFM to maximum of indoor unit. De-
fault is dependent on tonnage of indoor unit. Ad-
justments are in increments of 5 CFM .
Zone 1
through
4 Cooling
CFM
Minimum and maximum CFM will be dependent
on system component congurations. These pa-
rameter values are automatically adjusted to the
specic hardware conguration. See iHarmony
zoning system installation instruction for minimum
CFMs for specic indoor units.
Target cooling CFM for a specic zone. Range is 5
CFM to maximum of indoor unit. Default is depen-
dent on tonnage of indoor unit. Adjustments are in
increments of 5 CFM.
