If all pins 1-
6 at S1 are simultaneously set to “ON”, the controller is set to “calibration mode”. This is only
necessary for troubleshooting. Each controller is delivered pre-calibrated and ready for operation, calibration
during commissioning is normally not necessary.
Setback mode
Optionally, a second, lower pressure level can be set for the set pressure level and activated externally, for
example by a timer.
Pin 1 at S2 must be set to “ON” to enable setback mode. The setpoint for setback mode is lowered by the
percentage value specified with switch S2, pins 2 to 4. The percentages of pins 2-4 at switch S2 are added
together.
The setback mode is activated by an external potential-
free closing contact at X3 “Reduc. Mode”.
If several exhaust fans are controlled via a timer, each exhaust fan requires a separate potential-
free NO contact to avoid reverse voltages.
Value range: OFF, reduction by 10-70%
Increments: 10%
Examples:
A: OFF
B: 50% reduction of the S1 setpoint
The test contacts are required for the production and in-house quality control of the pressure con-
trol. Under no circumstances must they be connected or short-circuited.
