Standalone operation

In the case of a standalone module the energy recovery control output signal is controlled by the temperature difference between the outside air temperature (this can be the real OAT value from the inlet air temperature sensor or the smooth filtered OAT value from the macro "Filtered Temperature") and the return air temperature. The temperature difference is defined by parameters ERS-03 and ERS-04 with a minimum and maximum output signal defined by parameters ERS-01 and ERS-02, as shown in the next figure.


Attention: Set the input "ERCCtrlSig" to the constant value 999 for stand-alone operation.
