Relay output for Heating or Cooling
Offset Digital Out = Offset for relay output (K2 is pre-programmed by the factory )
The relay operating point deviates by the adjusted offset of the Setpoint of the ventilation (if
relay K2 not inverted, terminal „21“-„24“ bridged).
0.0 K set, i.e.
heating „ON“ when: actual value = Setpoint
During negative offset value
heating „ON“ when: actual value = Setpoint - offset
During positive offset value
heating „ON“ when: actual value = Se offset
The switching hysteresis of the relay is set to 1 K at factory Hyst. Digital Out.
Example 1
Temperature variation with factory setting 9 K in IO Setup e. g. for controlling a
Heating
If the ambient temperature is lower than the set operating point, the heating remains switched on. If the ambient
temperature exceeds the set operating point of the heating by 2 K, the heating is switched off. I.e., the release point is
situated at the hysteresis value over the operating point.
The activated heating is indicated over the fire symbol in the display
Example 2
Temperature variation with reprogramming to 10K in IO Setup, e.g., for activation of the
cooling
If the ambient temperature is higher than the set operating point, the cooling remains switched on.
If the ambient temperature falls below the set operating point of the cooling by 2 K, it is switched off. I.e., the OFF point
is situated at the hysteresis value under the ON point.
