7 Cooling with room tem-
perature/humidity probe
Description of the Cooling Installation
Cooling via the mixed heating cycle
(surface heating cycle )
If the heat pump is to be used for cooling, then this
must be possible via the heating cycle. The
hydraulic connection is identical to the connection
for the heating cycle. If the mixed cycle is used for
heating or cooling, it will be connected as shown in
Fig. 42 and Fig. 41. The probes S12 and S11
measure the inlet and return flow temperatures, if a
heating/cooling buffer is used. Dew-point moni-
toring is required for this.
Dew point regulation via room temperature/
humidity probe
If cooling via the surface heating is also required in
summer, this can only be activated in conjunction
with the Smart-Control Touch and the appropriate
room temperature/humidity probe. Only with the
use of the REMKO room temperature/humidity
probe it is possible to use a cooling curve in order
not to fall below the dew point. The remote control
of the Smart-Control Touch regulation does not
have its own humidity probe, therefore the room
temperature/humidity probe must always be used if
surface cooling is required.
As of software version 4.24, the mixing valves can
mix at different inlet temperatures.
The water temperature in the pipes is main-
tained above the nominal dewpoint temperature
by the controller, in order to prevent the forma-
tion of condensation on the exposed pipes as
well as those concealed under the plaster.
It is also recommended to install a 230 V dewpoint
monitor with the associated pipe temperature sen-
sors to the feed pipes outside the heat pump. The
location should be selected so that it does not
favour the temperature falling below the dewpoint.
The dewpoint monitor is wired so that it divides the
connector in the feed line to the utility company
switch to the controller (inlet S16) or the external
heating cycle pump in order to switch off the heat
pump.
Cooling via a parallel buffer tank as a system
limit
If the system is operated using a parallel buffer
tank that acts as a system limit on the consumer
circuit, no probe must be installed in the living
room if the regulation of the consuming cooling cir-
cuit is operated via a third-party controller.
NOTICE!
Minimum water volume
If the system/water volume in the cooling circuit
provided by the customer is less than the min.
water volume, an additional buffer tank is rec-
ommended to increase the volume. This can be
incorporated as a serial buffer in the return flow
or as a hydraulic compensator. The KPS series
buffer tank can be supplied by REMKO for this.
