temperature controller with additional functions: Relay ouput 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 of temperature variation with factory setting 9 K in IO Setup e. g. for controling a
Heating
The activated heating is indicated over the fire symbol in the display
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.
Example of 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.
