DischTempCoolDB (AV80)
This variable is used to calculate if a cooling stage must be stopped. If the discharge temperature is
below DischTempCoolSP(AV79) – DischTempCoolDB(AV80), a cooling stage is stopped.
ID Units Valid Range Default Value
Analog Value 80 Delta-Degrees-Celsius (∆°C) 1 to 5∆°K 3∆°K
DischTempHeatSP (AV81)
This variable is used to calculate if another heating stage is required to heat the space. When the
space temperature is requiring heating, heating stages will be turned on only if the discharge tempera-
ture is below DischTempHeatSP(AV81).
ID Units Valid Range Default Value
Analog Value 81 Degrees-Celsius (°C) 26,5 to 65,5°C 32°C
DischTempHeatDB (AV82)
This variable is used to calculate if a heating stage must be stopped. If the discharge temperature is
above DischTempHeatSP(AV81) + DischTempHeatDB(AV82), a heating stage is stopped.
ID Units Valid Range Default Value
Analog Value 82 Delta-Degrees-Celsius (∆°C) 1 to 16,5∆°K 8 ∆°K
ExhaustStartSP (AV83)
This variable is used to configure the damper position above which the power exhaust is started.
ID Units Valid Range Default Value
Analog Value 83 Percent (%) 0 to 100% 50%
ExhaustStopSP (AV84)
This variable is used to configure the damper position below which the power exhaust is stopped..
ID Units Valid Range Default Value
Analog Value 84 Percent (%) 0 to 100% 25%
InitStartDelay (AV85)
This variable is used to configure the delay after a reboot of the controller before enabling the con-
troller.
ID Units Valid Range Default Value
Analog Value 85 Seconds N/A 120s
DischTempLowLimitSP (AV86)
This variable is used to calculate the LowLimitAlarm(BV17). When the fan is running and the dis-
charge temperature is lower than this value, the low limit alarm is set to alarm mode.
ID Units Valid Range Default Value
Analog Value 86 Degrees-Celsius (°C) 0 to 7°C 2°C
SpOffsetRange (AV87)
This variable is used to configure the setpoint offset range of either a remote control or the room sen-
sor.
