This function allows you to select a connected wiring
centre for the sensor and actuator test. The system con-
trol lists the actuators and sensors for the selected wiring
centre. If you confirm the selection of an actuator using
OK
, the system control activates the relay. The actuator's
function can now be checked. Only the activated actuator
is active, all other actuators are "deactivated" at this time.
For example, you can move a mixing valve in the "Open"
direction and check that it is connected the right way round
or activate a pump and check that it starts up. If you select
a sensor, the system control shows the measured value of
the selected sensor. For the selected component, read the
measured values from the sensors and check whether the
individual sensors are providing the expected values (tem-
perature, pressure, flow rate, etc.).

The display shows the current day and the target flow tem-

The day is always changed at 00:00, irrespective of when
the function starts.
After a mains Off/On, screed drying starts with the last active
day.
The function ends automatically when the last day of the
temperature profile has elapsed (day = 29) or if you set the
start day to 0 (day = 0).
