Alternative to 0-10 V control output, signal relay to control a fan

In addition to or as an alternative to the power output, a signal relay (see Electrical installation, relay
outputs chapter) can be used to control a fan (fan on/off).
Note:
The signal relay controls an optional contactor, dimensioned for the fan current.

Forced ventilation/Party

Information
If ventilation even without a difference (diff = 0) is required, a control contact / light switch can be used
to activate 100% ventilation.

L-BAL-E304-GB 2004
5 g/kg The full modulation (analog output) of 10 V is achieved
at 5 g/kg.
(suggestion)
0 - 10 V = 0 - 5 g/kg. > 5 g/kg always means 100 %
modulation with a 10 V output.
Modulation of the 0 - 10 V analog output. 0 % = 0 V,
100 % = 10 V
Value Meaning
1K Operating indication (default)
4K Limit modulation for fan control on/off
Value Meaning
OFF no message
5.0 Hz Value of max. control range at which the relay K2 shuts
off again.
For example, with 5 g/kg as the control range, the relay
shuts off again at 0.5 g/kg.
25 Hz Value of max. control range at which the relay K2
switches on.
For example, with 5 g/kg as the control range, the relay
switches on at 2.5 g/kg.
0 sec 0 = Immediate response without delay
Value Meaning
11D Max. speed setting is activated
