CO2 sensor, 2 PID setpoints

7.8 CO2 sensor, 2 PID setpoints
● 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.
