ANALOG VALUES
Receive Heartbeat AV:20 W cpRcvHrtBt
0 to 6553.4 sec
Default: 0
(Disabled)
Y
Specifies 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.
6
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). 6 See Space Temperature Setpoint
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
configured 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
configured 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
configured 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
configured 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

50 to 95ºF
10 to 35ºC
Default:
95ºF / 35ºC
Y
Maximum value of all the Occupancy Heating Setpoints.
It also specifies 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
