Connection of an external

enabling contact (optional)

Operation / standby

In addition to operation with the

controller or cabled remote con-

trol, the unit can be switched on

(standby) and off (normal opera-

tion) using an external ﬂoating

contact (programmed as an N.O.

contact) (Fig. 7).

A change in the function logic (as

N.C. contact) is not possible.

This enable is used, for example,

to implement downtimes at night

or an activation/deactivation of a

GLT.

Connection of the collective

fault

message notiﬁcation function

(standard equipment)

The connection of a ﬂoating col-

lective fault message notiﬁcation

function, for example, for signal-

ling or further processing on a GLT,

is possible in the standard version.

For this purpose, use the corre-

sponding connection diagram and

observe the maximum contact load

(Fig. 7).

Connection of an external

operating mode contact (op-

tional)

for cooling/heating mode

(units with heat pump func-

tion)

In the standard version, the unit

is programmed for operation with

the controller and/or cabled re-

mote control. If a switchover from

cooling or heating mode (Fig. 7)

should take place using an external

ﬂoating contact (input), parameter

SP 9 must be reprogrammed to

1 (for the programming, see the

"Conﬁguration of the switchover

between cooling and heating"

section). After the switchover, only

the external enable for cooling/

heating mode can be used.

Conﬁguration of the switchover between cooling and heating

(external contact)

The controller is programmed at the factory for the switchover between

cooling and heating on the controller. When an external contact is used

to switchover between cooling and heating, a regulation parameter must

be reconﬁgured. Parameter SP 9 must be switched over from 0 to 1. In

the SP menu item, the parameter SP 9 can be changed in level 1.

Factory setting for KWP...H heating:

Switchover between cooling and heating Parameter SP 9 = 0

"0" = operation on controller, "1" = operation through switchover con-

tact

The following program sequence must be programmed.

mode" is activated with an open contact between

terminals 2 and 6. Display =
