ANALOG VALUES
Receive Heartbeat AV:20 W cpRcvHrtBt
0 to 6553.4 sec
Default: 0
(Disabled)
Y
Species the maximum amount of time the supported
overrides must be refreshed (i.e. written) before the unit
reverts back to the default value. Each point supported by
Receive Heartbeat has a separate timer associated with it.
Only use this feature in BACnet v3.3 software and newer.
The value of 0 disables this feature.
Supported Receive Heartbeat points:
• AV 18
• AV 35
• MSV 1
• MSV 8
• MSV 9
• MSV 10
• MSV 11
• MSV 12
Send Heartbeat AV:21 W cpSndHrtBt
0 to 6553.4 sec
Default: 0
(Disabled)
Y
The Send Heartbeat function is not supported by the
BACnet communication module. Use the Change of Value
(COV) feature as an alternative.
Effective Space
Temperature Output
AV:22 R EffectSpaceTemp
0 to 158°F
-17.78 to 70°C
Default
6
:
621.806ºF
327.67ºC
N
Monitors the space temperature that the unit controller
uses for control. AV22 uses the AI1 local sensor unless the
AV18 network override is a valid value.

Effective Setpoint
Output
AV:23 R EffectSetpt
50 to 95ºF
10 to 35ºC
Default
6
:
621.806ºF
327.67ºC
N
Effective Heating or Cooling Setpoint the unit controller is
attempting to maintain, which is dependent upon Effective
Occupancy (MSV6).

Methods.
Occupied Cooling
Setpoint Shift Output
AV:24 R Occupied_CoolShift
-3 to 3ºF
-1.67 to 1.67ºC
Default: 0ºF
N
Represents the local hardwired setpoint adjustment value
from the room sensor potentiometer. It is valid when
congured for Short Range Setpoint Adjust.
Standby Cooling
Setpoint Shift Output
AV:25 R Standby _CoolShift
-3 to 3ºF
-1.67 to 1.67ºC
Default: 0ºF
N
Represents the local hardwired setpoint adjustment value
from the room sensor potentiometer. It is valid when
congured for Short Range Setpoint Adjust.
Unoccupied Cooling
Setpoint Shift Output
AV:26 R
Unoccupied
_CoolShift
Default: 0ºF N
This value represents the Unoccupied Cooling Setpoint
Offset that is always 0°F.
Occupied Heating
Setpoint Shift Output
AV:27 R Occupied_HeatShift
-3 to 3ºF
-1.67 to 1.67ºC
Default: 0ºF
N
Represents the local hardwired setpoint adjustment value
from the room sensor potentiometer. It is valid when
congured for Short Range Setpoint Adjust.
Standby Heating
Setpoint Shift Output
AV:28 R Standby _HeatShift
-3 to 3ºF
-1.67 to 1.67ºC
Default: 0ºF
N
Represents the local hardwired setpoint adjustment value
from the room sensor potentiometer. It is valid when
congured for Short Range Setpoint Adjust.
Unoccupied Heating
Setpoint Shift Output
AV:29 R
Unoccupied
_HeatShift
Default: 0ºF N
This value represents the Unoccupied Heating Setpoint
offset that is always 0°F.
Cooling Setpoint High
Limit
AV:30 W cpClgSptHiLim
50 to 95ºF
10 to 35ºC
Default:
90ºF / 32.22ºC
Y
Maximum value of all the Occupancy Cooling Setpoints.
The AV30 value must be greater than AV31.
Cooling Setpoint Low
Limit
AV:31 W cpClgSptLoLim
50 to 95ºF
10 to 35ºC
Default:
55ºF / 12.78ºC
Y
Minimum value of all the Occupancy Cooling Setpoints.
It also species the minimum allowed AI5 Long Range
Setpoint adjustment value. The AV31 value must be less
than AV30.
Heating Setpoint High
Limit
AV:32 W cpHtgSptHiLim
50 to 95ºF
10 to 35ºC
Default:
95ºF / 35ºC
Y
Maximum value of all the Occupancy Heating Setpoints.
It also species the maximum allowed AI5 Long Range
Setpoint adjustment value. The AV32 value must be
greater than AV33.
Heating Setpoint Low
Limit
AV:33 W cpHtgSptLoLim
50 to 95ºF
10 to 35ºC
Default:
50ºF / 10ºC
Y
Minimum value of all the Occupancy Heating Setpoints.
The AV33 value must be less than AV32.
Compressor Low
Pressure Alarm Delay
AV:34 W cpLowPresAlmDly
0 to 120 sec*
Default: 30 sec
Y
Species the time delay between the Low Pressure Input
and alarm generation for compressors.
*Range for unit controller software v2.9 and older is 0 to 99
seconds.
