We set up the controller’s digital outputs by keying in which
module and point on this module each one of these has been con-
nected to.
We furthermore select for each output whether the load is to be
active when the output is in pos. ON or OFF.
(Functions with relay:
A relay connection was reserved for each function when the
number of functions was defined. Keep the 0-0 setting for those
functions that are not going to use a relay connection. The line is
removed automatically when set up of the function continues).
The following displays will depend on the earlier definitions. The
displays will show which connections the earlier settings will
require. The tables are the same as shown earlier.
• Digital outputs
• Digital inputs
• Analog inputs
We set up the controller’s digital input functions by keying in which
module and point on this module each one of these has been con-
nected to.
We furthermore select for each output whether the function is to be
active when the output is in pos. Closed or Open.
All inputs are shown as DI1, DI2, etc.
We will change this name to the respective functions.
As such, DI1 will become Vtw (DI1), and
DI2 will become Vhr (DI2).

The possible functions are
the following:
Alarm, high priority
Alarm, all priority
Thermostat 1 - 5
Pressostat 1 - 5
Voltage input 1 - 5
4 - Digital inputs
Alarm mute:
Only shown if an alarm
relay has been defined and
it needs to be fitted with
a switch function (pulse
pressure).
DI 1- 16:
Definition of on/off inputs.
Synchronisation signal:
Only shown if a pulse
reading with related syn-
chronisation is defied. A
synchronisation signal can
be connected to the pulse
module.
Pulse reading:
Here pulse measurements
can be connected in ac-
cordance with DIN 43864.
Relay outlets are not used in our example.
