2.2 Operating mode
2.2.1 General
Function for setting and displaying all settings for current operating mode, i.e.
starting conditions, switch-o conditions and operating mode. The AHU can also
becontrolled via the control unit.
None.
None.
Configuration in Configuration 1 and Configuration 2 specifies various methods of
switching on the AHU.

Parameter Value Function
Current
– O
– On
– Damper motion
– Fire
– Stop
– Start-up
Operating mode:
– Switched o.
– Comfort mode.
– Fire damper test.
– Fire mode (depending on parameter setting for
fire mode).
– AHU stopped and blocked (regulator in start
phase, configuration not complete, alarm class
danger, emergency stop).
– AHU’s start-up procedure enabled.
Schedule – O
– Step 1…Step 3
Displays current control for timer control program
(only if Timer control prog. funct. = Step).
Go to the page for setting parameters of time
control program.
From BMS
– Auto.
– O
– Step 1
– Step 2
– Step 3
Displays control from BVMS (only if Time control
prog. funct. <> Step+Temp). The value can be set
via the control unit even when communication is
disabled.
– Auto mode: AHU can be switched in via time
control program, etc.
– AHU switched o.
– AHU operation in step 1 (uses setpoint value 1
for analogue outputs).
– AHU operation in step 2 (uses setpoint value 2
for analogue outputs).
– AHU operation in step 3 (uses setpoint value 3
for analogue outputs).
External control
– Auto.
– O
– Step 1
– Step 2
– Step 3
Displays current control from external control.
– Auto mode: AHU can be switched on via time
control program, timer, etc.
– AHU switched o.
– AHU operation in step 1 (uses setpoint value 1
for analogue outputs).
– AHU operation in step 2 (uses setpoint value 2
for analogue outputs).
– AHU operation in step 3 (uses setpoint value 3
for analogue outputs).
Power up delay 0…36000 [s] Delayed start after restart of regulator.
