Setting; Settings For Absolute Humidity Difference Control - Helios FU Comfort Sinus Manuel De Montage Et D'utilisation

Installation and Operating Specification FU Comfort Sinus
Fast modulation:
•
Sensor output 0 - 50 g/kg.
•
A control range of 5 corresponds to an output of 100 % output frequency.
•
Thus 0 - 5 g/kg corresponds to control from 0 - 100 % output frequency.
•
From 5 g/kg the maximum modulation is achieved at 100 % output frequency.
•
To achieve an output value of 100 % output frequency, the difference must be 5 g/kg.
Alternative to power output 0 - 100 % output frequency, control with on/off signal via relay
As an alternative to the power output with 0 - 100 % output frequency, an on/off signal can be used to
control a fan via a relay in the FU-C.
To boost the power of the FU-C relay, a contactor corresponding to the fan current must be selected.
If there is a difference, which means venting for drying is worthwhile, the relay is switched on. The fan
is switched on accordingly.
Forced ventilation independent of control
Independently of the difference control, a digital input on the FU-C, e.g. a light switch to be set by the
customer, can be used to activate forced ventilation mode.

Value Meaning
0 g/kg Setpoint 1 = Initial value
(suggestion) No control takes place at a variation of 0. If the variation
is >0 control starts.
100% = 10 V output depends on the set control range.
To compensate for tolerances in the measurement
chain, the initial value can be set to e.g. 0.5 instead of
0. Control thus begins from 0.5 g/kg.
