Adjustable range for setpoint offset output

Depending on the position of the setpoint wheel and manual switch of the wall module, the output voltage of the wall module will be in the range of 0…10 V. This voltage is the input of the wall module which translates this signal into the setpoint adjustment and the manual switch condition signals as shown in the next picture.

The setpoint offset is available at the output "ContrPtAdj" only for the operation modes day and automatic.

In these two modes the output will defined by the parameters CPA-01 for the minimum setpoint wheel position and CPA-02 for the maximum wheel position. In intermediate wheel positions the setpoint adjustment will be a linear function and will take the value „0“ in the neutral position of the setpoint wheel.
