Description
ANALOG VALUES
Occupancy Temperature Setpoints
(AV1 to AV6)
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 Rule
3
: AV1 > (AV4 + AV10)
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 Rule
3
: AV2 > (AV5 + AV10)
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 Rule
3
: AV3 > (AV6 + AV17)
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 Rule
3
: AV4 > (AV1 – AV10)
Standby Heat Setpoint AV:5 W
cpStandby_
Heat_Setpt
50 to 95ºF
10 to 35ºC
Default:
66ºF / 18.88ºC
Y
Denes the Space Temperature Setpoint for the Standby
Heat Setpoint.
Interaction Rule
3
: AV5 > (AV2 – AV10)
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 Rule
3
: AV6 > (AV3 – AV17)
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.
Interstage OFF Timer AV:8 W cpIntStgOffTmr
0 to 1200 sec
Default: 0
Y
A countdown timer that denes the minimum period of time
between turn-off of the subsequent heating and cooling
stages. The Interstage OFF Timer is not supported by unit
controller software.
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.
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
Sets the Occupied and Standby setpoint hysteresis that
determines the Effective OFF setpoints.
Compressor Low
Suction Temp
Protection SP for
Glycol
AV:11 W cpLowTempProtGL
0 to 50°F
-17.78 to 10°C
Default:
6.5ºF/-14.16ºC
Y
Temperature at which a Compressor Low Suction alarm
occurs in heating mode when the loop uid is glycol. AV11
is enabled by the unit controller JP3 jumper in the shorted
position, selecting glycol.
AV11 does not apply to the dehumidication and cooling
modes, which use a xed 28ºF low temp threshold
regardless of the loop uid type.
Compressor Low
Suction Temp
Protection SP for
Water
AV:12 W cpLowTempProt
0 to 50°F
-17.78 to 10°C
Default:
28ºF / -2.22ºC
Y
Temperature at which a Compressor Low Suction alarm
occurs in the heating mode when the loop uid is water.
AV12 is enabled by the unit controller JP3 jumper in the
open position, which selects water.
AV12 does not apply to the dehumidication and cooling
modes, which use a xed 28ºF low temp threshold
regardless of the loop uid type.
Compressor Low
Suction Temp
Protection Differential
AV:13 W cpLowTmpProtDif
2 to 15°F
1.11 to 8.34°C
Default:
8°F / 4.44°C
Y
AV13 is added to the selected Compressor Low Suction
Temperature SP (AV11 or AV12) to determine the setting at
which the alarm clears.
