Activating the solar function
If the REMKO RBW domestic hot water heat pump is operated in conjunction with a thermal solar plant,
please note the following:
n T
o operate the heat pump in conjunction with max.7.5 m² solar collector surface, once the hydraulic con-
nection is established, it is also necessary to connect the collector probe supplied as standard. To do so,
use the appropriate measuring point on your collector surface and connect the probe to the connection
(Fig. 40), terminal 4. The solar collector pump is installed on terminal 2.
n Then remove the resistor, with which this connection is already equipped. This resistor should remain
with the unit, to ensure emergency operation in the event of a potential malfunction. If the REMKO RBW
domestic hot water heat pump is operated without the probe or resistor, an error is shown on the display.
Once installation of the thermal solar plant is complete and the collector probe has been connected, the
system is ready for operation. T
o optimise the installed system, it is also necessary to adjust the following
parameters on your system.

To adjust the parameters, perform the steps already described for configuring and activating the legionella
function in the relevant parameter menus.
Solar changeover valve
In order to increase solar yield, you have the option to use a changeover valve to charge an additional
storage tank (see example
