up to 29 characters. Name can consist of letters, numbers, special
characters and spaces. Default name is subnet controller.
HP Heating
Lockout Time
The HP could not get a zone to progress 0.5 degrees towards the
set point in 120 minutes (Alert Code 40 - Minor alert). System will
switch to secondary 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 60 minutes. Adjustments are
in increments of 30 minutes.
Zone 1 through
4 Continuous
Blower CFM
The maximum airow CFM is the factory default value for each
particular unit.
The per zone CFM value is the equal division of the number of
zones into the maximum airow default CFM.
These values will be veried and/or adjusted in the procedure listed
on pages 9-10 “Mapping the System”.
Zones requesting the fan ON are only allowed while no other zone
demand is present. The thermostat 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 priority demands, all other conditioning demands will over-
ride the continuous blower demand.
The minimum CFM is 250 CFM for 3-ton, 380 for 4-ton or 450 CFM
for 5-ton to the maximum .
Adjustment are in 5 CFM increments.
Zone 1 through 4
Cooling CFM
The maximum airow CFM is the factory default value for each
particular unit.
The per zone CFM value is the equal division of the number of
zones into the maximum airow default CFM.
These values will be veried and/or adjusted in the procedure
starting in “Mapping the Design” on page 9.
The maximum airow and per zone CFM is achieved by selecting
adequate air volume to maintain the design DAT within the 7°
operating range of the target air temperature value and the proper
indoor blower power percentage during the test procedures “Sizing
the System” on page 10 and “Testing the Zones” on page
11.
iHarmony minimum CFM may exceed proper delta T operating
ranges.
The minimum CFM is 250 CFM for 3-ton, 380 for 4-ton or 450 CFM
for 5-ton to the maximum .
Adjustment are in 5 CFM increments.
