3 = Null (no switch present)
System Mode Switch
(Heat/Cool/Auto) Status
MSI:3 R HeatCoolAuto 1 to 5 N
Displays the room sensor System Mode switch
(Heat/Cool/Auto) position.

MULTI-STATE VALUES
Compressor Enable
Input
MSV:1 C ComprEnable
1 to 3
Default: 3
N
Species if the compressor(s) are allowed to operate, which
can be based on proof of loop uid ow. The loop pump
must be running to provide adequate ow through the
WSHP. 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 1 to 16 N
Displays the current highest priority active alarm.
1 = No Alarms
2 = Low Voltage Brownout
3 = Comp#1 High Pressure
4 = Comp#2 High Pressure
5 = Comp#1 Low Pressure
6 = Comp#2 Low Pressure
7 = Comp#1 Suctn Temp Snsr Fail
8 = Comp#2 Suctn Temp Snsr Fail
9 = Comp#1 Low Suction Temp
10 = Comp#2 Low Suction Temp
11= Room Temp Sensor Fail
12 = Entering Water Temp Sensor Fail
13 = Condensate Overow
14 = Serial EEPROM Corrupted
15 = Invalid Conguration
16 = Low Entering Water Temp
Fan Speed Output MSV:3 R Fan Speed 1 to 5 N
Displays the commanded fan speed.
1 = Off
2 = Low
3 = Medium
4 = High
5 = On
McQuay WSHP Status MSV:4 R McQWSHPStatus 1 to 10 N
Indicates the unit’s operating state.
1 = Off Alarm
2 = Off*
3 = Start
4 = Fan Only* (fan is allowed to operate)
5 = Prepare to Heat
6 = Heating
7 = Prepare to Cool
8 = Cooling
9 = Prepare to Dehumidify
10 = Dehumidication
*State Indications:
• Unit controller software v3.0 and newer:
MSV-4 always matches unit controller state
• Unit controller software v2.9 and older:
When fan is off, MSV-4 indicates Off state, but unit
controller is actually in Fan Only mode
