This configuration is very important and should be the first step when setting the
parameters for a system!
Assignment of digital input
Def.
A21 Functional access digital input
One of the following functions can be assigned to the digital input
here. The digital input must be connected to a corresponding poten-
tial-free switch contact.
The digital input of the regulator may only be connected
to a potential-free switch contact!!
Do not apply any external voltage - risk of destruction!!

0: deactivated
1: Remote start cooling
The cooling can be started from the OFF mode via the digital
input. No further parameters need to be set to use this function.
2: external temperature switching T1/T2 [P80=4]
The digital input is used to switch the target temperature. For
this, this option must also be activated in parameter [P80] = 4
3: external compressor lock (see section 7.7.2)
4: Freeze protection via low pressure switch (see section 7.7.3)
5: Compressor fault monitoring (see section 7.4)
6: Safety switch cover of the milk cooling vat
(Switch off the agitator when the lid is on) see section 7.5
