Monitors the Condensate Overflow sensor input.
1 = Dry
1 to 3 N
2 = Wet
3 = Null (no sensor present)
Displays the room sensor fan On/Auto switch position.
1 = On
1 to 3 N
2 = Auto
3 = Null (no switch present)
Displays the room sensor System Mode switch
(Heat/Cool/Auto) position.

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
1 to 3
WSHP. The network override will revert back to its default
N
value upon unit controller reboot.
Default: 3
1 = Disabled
2 = Enabled
3 = Null (compressors are enabled)
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
1 to 16 N 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 Overflow
14 = Serial EEPROM Corrupted
15 = Invalid Configuration
16 = Low Entering Water Temp
Displays the commanded fan speed.
1 = Off
2 = Low
1 to 5 N
3 = Medium
4 = High
5 = On
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
1 to 10 N 9 = Prepare to Dehumidify
10 = Dehumidification
*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
