Description
ANALOG VALUES
Occupancy
Temperature
Setpoint
(AV1 to AV6)
General Interaction Rules
Denes the Space Temperature Heating and Cooling
Setpoints for different occupancy modes. See Effective
Occupancy Modes and Space Temperature Setpoint
Methods.
The Occupancy Temperature Setpoints must be kept in
ascending order as follows:
AV6 <= AV5 <= AV4 <= AV1 <= AV2 <= AV3
Occupied Cooling
Setpoint
AV:1 W
cpOccupied_
Cool_Setpt
50 to 95ºF
10 to 35ºC
Default:
75ºF / 23.88ºC
Y
Denes the Space Temperature Setpoint for the Occupied
Cooling Setpoint.
Interaction Rules
3
• AV1 > (AV4 + AV10)
• AV1 <= AV30
• AV1 >= AV31
Standby Cool Setpoint AV:2 W
cpStandby_
Cool_Setpt
50 to 95ºF
10 to 35ºC
Default:
77ºF / 25ºC
Y
Denes the Space Temperature Setpoint for the Standby
Cool Setpoint.
Interaction Rules
3
• AV2 > (AV5 + AV10)
• AV2 <= AV30
• AV2 >= AV31
Unoccupied Cool
Setpoint
AV:3 W
cpUnoccupied_
Cool_Setpt
50 to 95ºF
10 to 35ºC
Default:
85ºF / 29.44ºC
Y
Denes the Space Temperature Setpoint for the
Unoccupied Cool Setpoint.
Interaction Rules
3
:
• AV3 > (AV6 + AV17)
• AV3 <= AV30
• AV3 >= AV31
Occupied Heat Setpoint AV:4 W
cpOccupied_
Heat_Setpt
50 to 95ºF
10 to 35ºC
Default:
70ºF / 21.11ºC
Y
Denes the Space Temperature Setpoint for the Occupied
Heat Setpoint.
Interaction Rules
3
• AV4 < (AV1 – AV10)
• AV4 <= AV32
• AV4 >= AV33
Standby Heat Setpoint AV:5 W cpStandby_
50 to 95ºF
10 to 35ºC
Default:
66ºF / 18.88ºC
Y
Denes the Space Temperature Setpoint for the Standby
Heat Setpoint.
Interaction Rules
3
• AV5 < (AV2 – AV10)
• AV5 <= AV32
• AV5 >= AV33
Unoccupied Heat
Setpoint
AV:6 W
cpUnoccupied_
Heat_Setpt
50 to 95ºF
10 to 35ºC
Default:
60ºF / 15.55ºC
Y
Denes the Space Temperature Setpoint for the
Unoccupied Heat Setpoint.
Interaction Rules
3
:
• AV6 < (AV3 – AV17)
• AV6 <= AV32
• AV6 >= AV33
Local Bypass Time
Setpoint
AV:7 W cpBypassTime
0, 30 to 120 min
Default: 120 min
Y
Denes the amount of time that the unit can be in the
bypass mode initiated by the Timed Override button.
Pressing the Timed Override button 4-9 seconds sets the
bypass timer to the maximum AV7 value. The value of 0
disables this feature.
Cooling Interstage
Timer
AV:8 W cpCoolIntStgTmr
0 to 1200 sec
Default: 300 sec
Y
A countdown timer that denes the minimum period of time
between turn on of the cooling stages.
Brownout Reference
Setpoint
AV:9 W cpBrownoutRef
25 to 1023
counts
Default: 400
Y
AV9 is used to detect a unit controller brownout condition.
Brownout condition occurs when AI8 < 80% of AV9, and
clears when AI8 > 90% of AV9.
Note: Only perform the calibration procedure if the unit
controller 24VAC voltage is within normal operating
parameters. A password of 1023 is required.
Occupied Setpoint
Differential
AV:10 W cpOccDiff
1 to 5°F
0.55 to 2.78°C
Default:
1ºF / 0.55ºC
Y
This value represents the Occupied and Standby Setpoint
hysteresis to determine the Effective OFF setpoints.
