Description
This accessory is an electronic wall-
mounted individual room controller for
temperature regulation of indoor units
for cooling and heating. It automatically
controls the three fan stages and the
opening and closing of the valves for
more convenient temperature control.
The temperature can be measured by
the internal temperature sensor or by
a separate temperature sensor. The inlet
temperature can also be processed. Due
to a large number of program options,
the controller is very versatile and can be
optimally adapted to the system.
The precision room temperature
controller serves for the operation of the
unit series KWK, KWK-ZW, KWD EC,
WLT-S and DKT-4 within closed rooms
from a remote location.

Temperature controller
With the temperature control knob,
the desired setpoint can be set within
the range 5 to 35°C in 1°C steps.
Setting limit
If a limitation of the setting range is to
be implemented on the control knob,
the tabs located in the connection area
within the controller must be inserted
into the corresponding holes and,
if necessary, fixed.
Operation
The remote control is operated using
the relevant switches and temperature
controllers. If necessary, also use the
operating instructions of the unit being
operated.
Mode selector switch
The key is used to switch off "O" of the
controller and to select the operating
mode "Heating " or "Cooling ".
Fan selector switch
The fan level can be changed by
actuating the selector switch. There
are 3 fixed settings ("I" = low,"II" =
medium and "III" = high) as well as an
automatic level ("AUTO"). In "AUTO"
level, a large temperature deviation from
the adjusted set point activates a high
level and in the case of a small deviation,
a low level.

Adjustable systems and
functions
Two-wire system with one valve for
cooling or heating (J1=B):
The controller can be used to control
a system with a heating/cooling valve
in a two-wire system: a system with
a valve-controlled, half-yearly generated
warm medium in winter, e.g. through
a boiler, and half-yearly generated
cold medium in summer, e.g. through
a chiller. But also unswitchable, e.g.
air-water or brine-water heat pumps can
feed a two-wire system.
A heat exchanger in the indoor unit can
then give off the heat or cold.
Only a valve connected to terminal 7-8
regulates the medium-side flow rate in
the heat exchanger of the indoor unit in
both operating modes.
The operating modes can be switched
manually at the controller by means
of the operating mode selector switch
or automatically by means of the inlet
temperature sensor SM.
A heating valve connected to terminal
7-8 and a cooling valve connected to
terminal 8-9 regulate the medium-side
flow rate into the heat exchanger of the
indoor unit in both operating modes.
The operating modes can be switched
manually at the controller by means
of the operating mode selector switch
or automatically by means of the inlet
temperature sensor SM.
Four-wire system with a valve for cooling
and a valve for heating (J1=A):
The controller can be used to control
a system with a cooling valve and
a further heating valve in a four-wire
system: a system with a valve-controlled,
half-yearly generated warm medium
in winter, e.g. through a boiler, and
a second system with half-yearly
generated cold medium in summer,
e.g. through a chiller.
A heat exchanger "cooling" and
a further heat exchanger "heating"
in the indoor unit can then give off the
respective heat or cold.
Two-wire system with a valve for cooling
and an electric heating element for
heating:
The controller can be used to control
a system with an electric heating
element for heating and a valve for
cooling in a two-wire system: an electric,
half-yearly heating element in winter,
and a second system with half-yearly
cold medium in summer, e.g. by a chiller.
A heat exchanger for cooling and
an electrical heating element for heating
in the indoor unit can then give off the
respective heat or cold. An electrical
heating element connected to terminal
7-8 and a cooling valve connected to
terminal 8-9 regulate the control of the
heating element and the medium flow
rate on the medium side in the heat
exchanger of the indoor unit.
The operating modes can be switched
manually at the controller by means
of the operating mode selector switch
or automatically by means of the inlet
temperature sensor SM.
If heating elements are used, it is
necessary to have the fan run on after
the heating element has been switched
off to suit the local conditions (to be
provided by the customer).

Mode of operation ON-OFF valve
Inlet temperature sensor SM, alternative
bimetallic thermostat BC (terminal 11-12)
The controller is equipped for use
with an SM inlet temperature sensor
(available as an accessory) or a BC
bimetallic thermostat.
When positioning the inlet temperature
sensor SM on the supply line to
the indoor unit, the controller can
automatically switch to the operating
mode corresponding to the measured
medium temperature (automatic
changeover).
In this case, the heating mode is
activated at a measured temperature
of >30°C and the cooling mode at
a measured temperature of <17°C.
Alternatively, a bimetallic thermostat
BC can be used at the same inlet for
positioning at the heat exchanger, which
releases the fan operation in heating
mode when a minimum temperature
is reached (see chapter "Minimum
temperature medium").
The maximum cable length of 25 m
must not be exceeded.
External room temperature probe SA
(terminal 13-14)
The controller has an internal
temperature probe (J4=A). If the
controller is not going to be located in
the room to be controlled, an optional
room temperature probe accessory can
determine the temperature (J4=B).
The maximum cable length of 25 m
must not be exceeded.
Measuring temperature
The controller measures the temperature
by means of the internal NTC probe
in the controller or on an external
room probe SA, which is available as
an accessory.
If the inlet temperature probe SM or
alternatively a bimetallic thermostat
BC is not used, a jumper between
terminals 11-12 must be provided!
NOTE
Minimum temperature, medium heating
When using a BC bimetallic thermostat,
the fan is only enabled when the bimetal
contact (contact 11-12) is closed. The
use of a inlet temperature probe is then
not possible.
When using an enabling contact
CF and bimetallic thermostat BC,
certain safety restrictions must
be observed. Please refer to the
corresponding chapter.
CAUTION!

General notes
The controller is suitable for controlling
three-stage fan convectors.
The fan stages are controlled by three
potential-free relay outputs at terminals
3 to 5.
The controller is designed for controlling
ON/OFF valves or an electric heating
element. Terminals 7-8 are for heating
output and terminals 8-9 for cooling
output.
External input
Enabling contact CF (terminal L-10)
The controller can be disabled or enabled
by an external potential-free contact.
Operation and temperature control are
not possible when disabled.
As long as the CF input is connected, the
controller cannot be operated.
Additional notes
1. The positioning of the inlet
temperature probe must be selected
in such a way that the temperature
can also be measured when the valve
is inactive.
2. Individual probes may not be used
for several controllers.
3. Only one temperature probe may be
used at the terminals.
4. All probes, bimetallic or enabling
contacts connected must be
insulated accordingly.
5. An all-pole disconnecting main
switch and a fuse must be provided.
6. The connection of all external
contacts, e.g. enabling contacts,
must be galvanically isolated from all
live and earthed parts of the system.
7. If persons can reach the hazardous
areas of external contacts, special
safety measures must be taken (e.g.
safety extra-low voltage).
8. The controller cover may only be
opened in de-energised state.
