6.2 Controller operating principle
6.2.1 Pump operation
The solar system is operated fully-automatically all year round
without the need for manual intervention. The speed-controlled
pump operation is controlled by the Solaris R4 controller. The op-
erating and display elements are shown in fig. 6-1.
Criterion for actuation:
– Pump operation depends on the continuously measured tem-
perature difference between the solar panel (T
K
) and the
return flow temperature (T
R
) and a comparison with the set
value of the parameter "Delta T on".
The solar operating pump P
S
switches on if the temperature
difference (=T
K
– T
R
) exceeds the value set in the parameter
"Delta T on" (e.g. return temperature = 40 °C and "Delta T on"
= 15 K; solar panel temperature > 55 °C).
Criteria for switching off:
– The solar operating pump P
S
switches off if the temperature
difference falls below the value set in the parameter
"Delta T off".
1. Possibility: Normal switch-off if the "Filling time" (parame-
ter "Time P2") has expired and the temperature difference
between the flow and return temperatures achieves the
switch-off condition (T
V
– T
R
<"Delta T off").
2. Possibility: Rapid switch-off if the solar panel cools off too
quickly within the "Filling time" (parameter "time P2")
(T
K
– T
R
<"Delta T off").
1 Main switch with indicator light
2 Display of temperature and parameter dis-
play (energy saving function: Display illumi-
nation is switched off 10 minutes after the
last key actuation)
3 Light for collector temperature display
4 Light for solar flow temperature and flow
measurement (FLS)
5 Light for storage cylinder temperature dis-
play
6 Light for solar return flow temperature dis-
play
7 Operating status light for speed-controlled
solar operating pump P
S
(lights up when
pump running - flickers if the pump is run-
ning in a restricted condition)
8 Up arrow for moving the temperature or pa-
rameter display up by one setting/increas-
ing parameter settings
9 Down arrow for moving the temperature or
parameter display down by one setting/de-
creasing parameter settings

tion level (displays measured values, max-
imum values and calculated values) and
OK key for confirming and storing settings
in the setting menu

The Solaris R4 controller has been fitted with an update
function for optimum use of the solar system, based on
continuous improvements. Therefore, some functions
described in this chapter are applicable to specific
software versions only. These functions are indicated
separately by symbols.
Software updates for the Solaris R4 controller must
only be carried out only by the ROTEX service tech-
nician.
The mains switch completely separates the Solaris R4
controller from the mains power. Switching of the mains
switch takes more effort in pushing the button than is
required for actuating the operating buttons.
