Description
MULTI-STATE VALUES
Compressor Enable
Input
MSV:1
C
ComprEnable
1 to 3
Default: 3
N
Specifies if the compressor(s) are allowed to operate, which
can be based on proof of loop fluid flow. The loop pump
must be running to provide adequate flow through the unit
so the compressor(s) can operate safely. The network
override will revert back to its default value upon unit
controller reboot.
1 = Disabled
2 = Enabled
3 = Null (compressors are enabled)
Current Alarm
MSV:2
R
CurrentAlarm
SmartSource
(Series2)
1 to 16
Enfinity Large
Two Compressor
(SS2C)
1 to 20
N
Displays the current highest priority active alarm
SmartSource (Series2) Alarms
1 = No Alarms
2 = IO Exp Communication Fail
3 = Invalid Configuration
4 = Low Voltage Brownout
5 = Comp High Pressure
6 = Comp Low Pressure
7 = Comp Suction Temp Snsr Fail
8 = Comp Low Suction Temp
9 = Freeze Fault Detect
10 = Room Temp Sensor Fail
11 = Enter Water Temp Snsr Fail

Fan ON/Auto Remote
Input
MSV:3
C
RemoteFanOnAuto
1 to 3
Default: 3
N
Overrides the local fan ON/Auto room sensor and
thermostat switch inputs. The local Fan ON/Auto Switch
is only used when MSV:3 is set to 3 (Null). The network
override will revert back to its default value upon unit
controller reboot.
1 = Fan Auto (forces cycling fan)
2 = Fan On (forces fan on)
3 = Null (no override)
McQuay WSHP Status
MSV:4
R
McQWSHPStatus
1 to 10
N
Indicates the unit’s operating state.
1 = Off Alarm
