9.4.1.2 Example for two-position control independent of the ventilation nominal value
•
In installation menu “ Mode 1 ” = Two-position controller, heating input: “ 1 ” = “ E2 ”
•
Current heating value from sensor on input “ E2 ”

Heating Setpoint
Heater switch-on adjustable as a separate setpoint (i.e., in ° C)
Setting range: -10.0...+40.0 ° C
Factory setting: -2.0 ° C

if the temperature around the hysteresis is below the switch-on point.
Setting range: -10...+10 K
Factory setting: 0.5 K
Attention!
When setting a negative hysteresis, the function is inverted, i.e., “ Cooling function ”

9.4.2 Controlling the heating via the 0...10 V signal (linear)
Example for controlling the heating via the 0 - 10 V signal (mode 2 = proportional controller)
The heating, activated through the 0 - 10 V signal, is indicated in the display with the
fi re symbol as
soon as the activation exceeds “ 0 % ” .
The “ K2 ” heating relay is connected in parallel in order to activate, for example, a gas valve.
