Typical applications for universal setpoint shift are:
Application
• Refrigeration: Shifting the flow temperature setpoint for the chilled ceiling
according to room enthalpy or surface temperature
• Ventilation: Shifting according to room humidity or surface temperature
9.10.3 Troubleshooting
When you leave the commissioning menu, the universal controller checks whether
a sensor is connected.
Sensor connected?
• If, at that time, a sensor is connected, but is missing later, a sensor error
message is delivered and presented on the display:
– "Xx ---" => sensor missing
– "Xx ooo" => short-circuit
• If, at that time, the sensor is not connected, setpoint compensation will be
deactivated
