REMKO KWL 130 H - Manual (Page 27)

Cabled remote control
(Accessories)
The cable remote control is used,
for example, for the querying,
programming or operation of
the unit from a remote location.
Use respective installation
instructions for this purpose.
(See section "Configuration exter-
nal enabling").
This enable is used for example to
realise standstill times at night or
for the activation/deactivation of
a building control system. Winter pressure controller
(Accessories)
It serves for the expansion of the
operating range in cooling mode
from +15 °C to -15 °C. The set
consists of crank case heating and
the pressure controller. Use respec-
tive installation instructions for this
purpose.
External enabling configuration
With the use of a normally open contact as an external contact a param-
eter of the controller must be reconfigured. The parameter CF 16 must
be switched from 0 to 1. If this does not happen, the controller does not
recognise the external contact as a normally closed contact. In the menu
item CF
the parameter CF 16 can be changed in Level 2. The following
program sequence must be programmed.
Configuration parameter CF 16
■ After the programming, "stand
by" mode is activated with the
contact open between terminals
2 and 3.
Display = OFF.
■ After the programming the
"cooling mode" is activated
with a closed contact between
terminals 2 and 3.

General fault signal
(Standard equipment)
The connection of a potential free
general fault signal, for exam-
ple, for signalling or for further
processing to a building control
system is possible as standard
equipment. Use the respec-
tive connection diagram for this
purpose and pay attention to the
maximum contact loads (Figure 8).

Compressor (standard/accessory)
The heating serves for the ex-
pansion of the operating range
in cooling mode from +15°C to
+5°C. For this purpose, use the
respective installation instructions.
For units with HP function this is
factory-installed. External operating mode contact
Cooling mode/heating mode
(units with HP-function)
By default, the unit is programmed
to be operated using the controller
or cable remote control. If a switch
from cooling or heating mode is
to be carried out over an external
potential free contact (intake),
(Figure 7)
, the CF 28 parameter
must be reprogrammed to 1 (pro-
gramming see section "Configura-
tion external enabling"). Only the
external enabling cooling/heating
mode can be used after switching.
