5.5.4 Temperatur deviation alarms
– For supply air deviation alarm, a supply air sensor must be available:
Main Index > Configuration > Configuration 1 > Supply tmp sensor = Yes.
– Deviation alarm tmp must be enabled:
Main Index > Configuration > Configuration 2 > Deviation alarm tmp<> No
– For room air deviation alarm, a room or return air sensor must be available:
Main Index > Configuration > Configuration 1 > Room tmp Sensor = Yes.
Setpoint/actual value monitoring of temperature: An alarm is triggered for the fol-
lowing cases when the temperature deviates from the setpoint during a certain pe-
riod:
– Actual value < Min limit.
– Actual value > Setpoint + maximum.
– Actual value < Setpoint – maximum.
– When setpoint – maximum < Min limit, min limit applies as the comparison value.
Main Index > Unit > Temp control > Tmp setpoints > Sply tmp dev alarm

5.5.5 Supply Minimum Maximum Controller
– Main Index > Configuration > Configuration 1 > Tmp control mode = Room oder
Exhaust
– Main Index > Configuration > Configuration 1 > Supply tmp sensor = Yes
Limits the supply air temperature for pure room or return air control to prevent dis-
charge temperatures that are too high or too low.

Functions
Function
Alarm state. Go to settings page for digital alarms. Set all
control-related settings such as alarm delay (default 3600
s).
An alarm is triggered below this temperature.
Maximum allowable deviation between setpoint and actual
value.
The function is activated after this period after a start.
Function
Present value for the minimum limit controller. Go to con-
troller settings page. This is where you enter all control-
related settings.
Present value for the maximum limit controller. Go to con-
troller settings page. This is where you enter all control-
related settings.
Lowest allowable supply air temperature for pure room
temperature or return air temperature control. A controlled
limiting of the cooling setpoint controller occurs for supply
