HP
Select the range that includes the desired compressor RPS for
inverter heating operation. See inverter manual for menu options
H
Maximum Compressor RPS for Heating Mode (inverter only)
Ht
Reset all heat pump heating settings to factory default.
Ht
Percentage of high stage heat pump heating airflow to run during
low stage operation. (default = 70%)
HtF
Heat Pump Indoor Airflow Trim (default = 0%)
HtH
High Heating Airflow Trim for Inverter Units. See inverter manual for
menu options and defaults
HtI
Intermediate Heating Airflow Trim for Inverter Units. See inverter
manual for menu options and defaults
HtL
Low Heating Airflow Trim for Inverter Units. See inverter manual for
menu options and defaults
LF
View 6 most recent fault codes and clear all fault codes if desired.
(furnace)
Ln
Restart communications between the indoor and outdoor unit.
D
Select the number of stages for the non-communicating outdoor
unit. Default = OFF meaning no outdoor unit.
PPd
Enable Pump Down Mode
Fd
Resets furnace settings to factory defaults.
Ct
Maximum Current Option (system will limit capacity to percentage
of maximum current) (default = 100%)
Control Shared Data Revision Number
t
Resets all outdoor unit settings to factory defaults.
t
System Verification Test (inverters only)
tn
Indoor Airflow for non-communicating outdoor units. (values based
on 400CFM per ton) (default = 3.0 Ton)
t
Select Outdoor Unit Elevation (SL=same level, OL = outdoor lower,
IL = indoor lower) Default = Outdoor Lower
CF
1 = system will try to satisfy the thermostat quickly.
5 (default) = system will try to satisfy the thermostat more slowly.
tgt
Menu is enabled if the
CF
menu is set to 6. Select the target time
the system will attempt to satisfy the thermostat.
UP
Menu is enabled if the
CF
menu is set to 6. Select the percentage
past the target time when the system will transition to gas furnace
operation during heat mode.
tt
Menu is enabled if the
CF
is set to 6. (the gas furnace will run
during the next heat call if the heat pump fails to satisfy the
custom target time for this number of consecutive cycles) (default
= 20 cycles)
Utt
Menu is enabled if the
CF
menu is set to 6. (if low stage gas heat
is able to consecutively satisfy the thermostat under the set target
time for this number of cycles, the system will transition to the
heat pump for primary heating)
dP
Menu is enabled if the
CF
menu is set to 6. (this percentage will
help determine when switching back to heat pump operation is
appropriate. Default = 20%. If target time = 20 minutes, low stage
furnace operation must satisfy the thermostat by less than 16
minutes. (target time - 20% default = 16 minutes).
