4.3 Changeover summer/
winter mode
During the usual heating period (from around
October to the start of May of the following year),
the REMKO heat pump must provide constant heat
for the heating operation.
The heat pump, circulation pumps and heating sur-
faces are constantly in operation, in order to keep
all rooms at the desired temperature. However,
during the summertime warming up the heating
surfaces is not necessary.
So-called summer mode exists to prevent the heat
pump continuing to produce heat to warm the
building during the warmer months. With this
mode, the heat pump is controlled such that the
heating operation and circulation pumps for the
heating surfaces only go into operation if a certain
temperature limit is undershot at the external
probe.
The basic setting of the REMKO Smart-Control
Touch controller is 16 degrees if no adjustment has
been made to the desired room set temperature.
The adjustment of this summer/winter changeover
is described in the following steps.
Heating limit
The heating limit of the Smart-Control Touch con-
troller is coupled with the room set temperature via
the parameter "Difference from heating limit".
In the following diagram, the possible value setting
for the different building types is to be determined.
The information in the diagram pertains to a room
set temperature of 20 °C.
