Description
ANALOG VALUES
Compressor Low
Suction Temp
Protection SP for Glycol
AV:11 W cpLowTempProtGL
0 to 50°F
-17.78 to 10°C
Default:
6.5ºF/-14.16ºC
Y
AV11 is enabled by the unit controller JP3 jumper in the
shorted position, which selects glycol loop uid.
Unit controller software v3.1 and newer
• Temperature at which a Compressor Low Suction
alarm occurs in the Heating mode when the loop uid
is glycol.
• AV11 does not apply to the Dehumidication and
Cooling modes, which use a xed 28ºF low temp
threshold regardless of the loop uid type.
Unit controller software v3.0 and older
• Temperature at which a compressor low suction
alarm occurs when the loop uid is glycol.
Compressor Low
Suction Temp
Protection SP for Water
AV:12 W cpLowTempProt
0 to 50°F
-17.78 to 10°C
Default:
28ºF / -2.22ºC
Y
AV12 is enabled by the unit controller JP3 jumper in the
open position, which selects water loop uid.
Unit controller software v3.1 and newer
• Temperature at which a Compressor Low Suction
alarm occurs in the Heating mode when the loop uid
is water.
• AV12 does not apply to the Dehumidication and
Cooling modes, which use a xed 28ºF low temp
threshold regardless of the loop uid type.
Unit controller software v3.0 and older
• Temperature at which a Compressor Low Suction
alarm occurs when the loop uid is water.
Compressor Low
Suction Temp
Protection Differential
AV:13 W cpLowTmpProtDif
2 to 15°F
1.11 to 8.34°C
Default:
8°F / 4.44°C
Y
AV13 is added to the selected Compressor Low Suction
Temperature SP (AV11 or AV12) to determine the setting at
which the alarm clears.
Heating Interstage
Timer
AV:14 W cpHeatIntStgTmr
0 to 1200 sec
Default: 300 sec
Y
A countdown timer that denes the minimum period of time
between turn on of the heating stages.
Compressor Minimum
OFF Timer
AV:15 W cpMinCompOffTmr
0 to 1200 sec
Default: 360 sec
(Unit Control
v3.1 & Newer)
Default: 180 sec
(Unit Control
v3.0 & Older)
Y
A countdown timer that denes the minimum period of time
compressors must remain OFF before it is allowed to turn
ON again.
Compressor Minimum
ON Timer
AV:16 W cpMinCompOnTmr
0 to 1200 sec
Default: 180 sec
Y
A countdown timer that denes the minimum period of time
compressors must remain ON before it is allowed to turn
OFF again.
Unoccupied Setpoint
Differential
AV:17 W cpUnoccDiff
2 to 10°F
1.11 to 5.56°C
Default:
2ºF / 1.11ºC
Y
Sets the Unoccupied hysteresis to determine the Effective
OFF setpoints.
Space Temperature
Input
AV:18 C
Network
SpaceTemp
14 to 122°F
-10 to 50°C
Default
6
621.806ºF
327.67ºC
N
Provides a space temperature value from the network
instead of using the local temperature sensor.
6,7
The
network override will revert back to its default value upon
unit controller reboot.
Temperature Setpoint
Input
AV:19 C Setpoint
50 to 95ºF
10 to 35ºC
Default
6
621.806ºF
327.67ºC
N
Allows the network to set the Reference Setpoint in
the Occupied and Standby Occupancy modes. Local
setpoint operation must be disabled by MSV14. AV19
always retains the last valid value after power-up.
6
The
network override will revert back to its default value upon
unit controller reboot. See Space Temperature Setpoint
Methods.
