External enabling contact
Operation/Standby
In addition to being operated
with the controller or the cabled
remote control, the unit can be
switched on (normal operation)
and switched off (Stand-By) via
an external potential-free contact
(normally-closed).
The contact is equipped with
a wire jumper in the factory.
The unit is enabled in this
condition.
If the contact is opened, the unit
is disabled and OFF is shown
in the display.
Changeover
cooling/heating mode
This changeover contact enables
the unit to be switched to cooling
mode or heating mode from
a remote location.
The changeover of operating
mode must be implemented
both through the connection/
disconnection of the external
changeover contact and through
the setting in the controller display.
If the contact is open and
the unit is switched to cooling
mode (snowflake) via the setting
in the controller display, the unit
operates in cooling mode.

The connection of a general
alarm signal, for example, for
signalling or for further processing
to a building control system
is possible as standard equipment.

this contact during normal unit
operation. As soon as a fault is
diagnosed on the unit, 230V
is present on the respective
terminals of the alarm contact.
