Cnfg Ctl
(CVAHU configuration for control)
Figure 60: Parameter Cnfg Ctl Hp Type
HP TYPE:
Displays and allows modification of heat
pump type selection as; CON, GSHP, ASHP.
Default configuration:
CON
Configuration settings in program are as follows:
0 = CON (Conventional control)
1 = GSHP (Water Source Heat Pump, WSHP.
Heat Pump Control with water status enable signal)
255 = ASHP (Air Source Heat Pump, ASHP.
Heat pump control without water status enable signal)
Figure 61: Parameter Cnfg Ctl Clg Type
CLG TYPE:
Displays and allows modification of
number of cooling/heat pump stages as: NONE,
1STG, 2STG, 3STG, 4STG, ANA.
Default configuration:
2STG
Configuration settings in program are as follows:
0 = NONE, 1 = 1STG, 2 = 2STG, 3 = 3STG,
4 = 4STG, 10 = ANA
Figure 62: Parameter Cnfg Ctl Clg Tr
CLG TR:
Displays and allows modification of space
cooling PID control throttling range. Its value ranges
from 0 to 30
∆F.
Throttling Range (TR):
When TR is nonzero, this value of TR is used by the
space cooling PID control.
Auto Gain Selection:
When TR is 0,
shows the TR values are used
by the space cooling PID control.

Note:
1. Modulating cooling not compatible with
Econo_Type = 1 Packaged.
2. Modulating compressor is not supported
for heat pump control.
3. Automatic Gain Selection feature is
enabled when Throttling Range (TR) is 0.
Default TR is 0.
