CO2 sensor, 2 PID setpoints

4.8
Macro 112 "CO2 sensor, 2 PID setpoints"

ON/OFF and PID setpoint selection via DI0 or DI2

Set the fixed setpoint (50 % corresponding to the

CO2 equivalent 1000 ppm)
External alarm at DI1. The fan is stopped.

Error message: Digital output 0

 Status display: Digital output 2
 If DI0 and DI2 are active simultaneously, the
setpoints are added. The drive starts when one of
the inputs is in ON position.
