Pre runtime Time from the heating relay is picked up until heating is physically supplied (flush
time)
Adjust heaters 0-10V
Heater min. voltage At heating requirement, the analogue voltage will never be lower than Minimum
voltage.
Heater max. voltage The heating shunt works at maximum output at this voltage
11.1.2 Central exhaust
11.1.2.1 Setting of exhaustion (MultiStep)
MultiStep is a method for controlling one or more exhaust units in steps, so that the exhaust output becomes
stepless.
The controller controls one or two exhaust units stepless from zero to 100 %, while the rest of the exhaust units
are switched on in steps as required. The controller can regulate up to 8 MultiStep units. The two stepless ex-
haust units can be connected in parallel or sequentially.
Every exhaust unit is equipped with a DA 74C swivel shutter motor, which can open and close the swivel shut-
ter.
The DA 74CV is used for the stepless exhaust unit(s). The internal fan speed controller in the climate controller
or an external fan speed controller controls the fan revolutions. The fan must always be single-phase, or else an
external DOL 31 must be used.
The DA 74CO ON/OFF is used for the other exhaust units. When the shutters open, the fans start via an inte-
grated switch. These fans will then run at their maximum. The fans can be single-phase or three-phase. If three-
phase fans are used, the DA 74CO ON/OFF winch motors must be equipped with contactors, which are con-
trolled by an integrated switch.
The system can also handle an air-operated shutter (wall fan).
