1.1 Mounting
The unit must only be located in dry interior locations. It
is not suitable for installation in hazardous locations and
should not be placed close to any electromagnetic fields. The
controller must additionally be supplied from a double-pole
switch with contact gap of at least 0.12". Please pay atten-
tion to separate routing of sensor cables and mains cables.
1. Open the front cover by pushing it. Unscrew the cross-
head screw from the cover and remove it along with the
front cover from the housing.
2. Mark the upper fastening point on the wall and drill and
fasten the enclosed wall plug and screw leaving the head
protruding.
3. Hang the housing from the upper fastening point and
mark the lower fastening point through the hole in the
terminal box (centres 5.3"). Drill and insert the lower
wall plug.
4. Hang the housing from the upper fastening point and
attach with the lower screw.
5. Carry out connection in accordance with the terminal
allocation.
6. Insert cover and attach with the cross-head screw. Close
the front cover properly.

The controller is equipped with 13 sensor inputs in total.
The ground connection for the sensors has to be carried
out via the ground terminal block (GND).
• Temperature sensors have to be connected to the
terminals S1 ... S10 and GND (either polarity).
• The irradiation sensor (CS10) is to be connected
to the terminals CS10 and GND with correct polarity.
Connect the terminal GND of the sensor to the terminal
GND of the controller (ground terminal block), and the
terminal CS of the sensor to the terminal CS10 of the
controller.
• A flowmeter can be connected to the terminals Imp and
GND (either polarity).
• An external message signal can be connected to the
digital input Din. When the signal contact closes the
input Din, the message “!message ext.” is generated.
This signal is treated like an error, which means that the
control lamp flashes red and the message relay is possibly
energized.
1.2.5 Power supply
The power supply to the controller must be carried out
via an external power switch (last step!) and the supply
voltage must be 115 V~ (50 ... 60 Hz). Flexible cables must
be attached to the housing with the enclosed strain relief
and the corresponding screws or be run into the controller
housing in a cable conduit or trunking.

3.3 Menu structure
Adjustment and control of the controller are carried out
via the menu. When the controller is commissioned, the
display level is in the status menu. In the first line of each
submenu you will find the option “back”, by means of which
it is possible to get to the former menu level. In the follow-
ing diagrams you will find the complete menu contents;
since some of the menu points depend on the system, op-
tion or message, in some cases not all of the shown text
lines are indicated.

Adjust the minimum runtime of the filter pump, in hours.
The pump will be switched on every day for this period of
time. This adjustment value is variable and has to be passed
through until the reference point (07:00 p.m.).
Example: When the filter runtime is adjusted to 5 hours,
the filter pump has to start at 02:00 p.m. and
continuously run until 07:00. p.m.
The minimum filter runtime will also be maintained in the
case of a sensor fault.

When the solar thermal system has been off for 1 hour, it

ming pool circulates through the pipes; this allows the pool
temperature to be detected during system standstill). If the
flow emergency shutdown is active, the circualtion function
is suppressed.

Expert/Adj. values/DTAH. Solar
adjustment range: 0.3 ... 20.0 K
factory setting: 1.0 K
The function starts when the pool is being loaded. Solar loa-
ding means that pool loading is only carried out for energy
supply and not for cooling purposes etc.
Backup heating is suppressed when the temperature diffe-
rence between flow and pool (AH solar on) is reached. If the
temperature difference falls below the value “AH solar off”,
the optimisation function switches off.
The adjustable minimum difference between switch-on tem-
perature and switch-off temperture (hysteresis) avoids that
the controller switches on and off again at too low tempe-
rature differences.

Extra filter runtime
Expert/Options/Extra circ.
and adjust:
Expert/Adj. values/Extra circ.
adjustment range: 1 ... 20 h
factory setting: 2 h
This option is used for switching on an extra runtime of the
filter pump (in h) if necessary (e.g. in the case of polluted
pool water).
As soon as a contact is detected at the Din input, the filter
pump starts and remains switched-on for the adjusted period
of time (extra runtime). The filter minimum runtime will not
be influenced by this function.
External release
Expert/Options/Ext. on/off
The external release function is used for releasing the pump
for solar loading (e.g. for preventing the controller from
switching on the pump during pump maintenance.) The
Din input must be closed to deblock the controller (solar
loading, afterheating).
Pool cooling function
Expert/Options/Pool cool.
and adjust:
Expert/Adj. values/DT-Cool.
adjustment range: 0.5 ... 10.0 K
factory setting: 2.0 K
Expert/Adj. values/ DT Cool on
adjustment range: 1.8 ... 10.0 K
factory setting: 3.0 K
Expert/Adj. values/ DT Cool off
adjustment range: 0.3 ... 9.7 K
factory setting: 1.5 K
If the maximum pool temperature is exceeded by the
adjusted value (DT-Cool), heat is diverted, provided that
the absorber is by at least DTCool on colder than the
pool. Cooling is switched off when the value DTCool Off
is reached.
Filter pump monitoring
Expert/Options/Pump monitor
selection “Yes” or “No”
When flowmeter is used and when the the filter pump is
switched on, this option monitors whether there is a flow
rate in the solar circuit. If the controller does not receive
any pulse after 2 minutes, the filter pump will be switched-
off and an error message will be generated.
Adjust the sensor type for the solar irradiation sensor
(A to E).
Sensors:
Expert/Sensors
Expert/Sensors/CS-type
Adjust the sensor offset.
An offset (-5K ... +5K, in 0.1 K steps) can be allocated to
each sensor in order to match the sensors with each other.
Expert/Sensors/CS adjust
Expert/Sensors/CS offset
Expert/Sensors/Sensor 1 etc.
The adjustable minimum difference between switch-on
temperature and switch-off temperture (hysteresis) avoids
that the controller switches on and off again at too low
temperature differences.
Operating relay:
Expert/Options/Operat. relay
selection: “Yes” or “No”.
The operating relay option can be selected. If the operating
relay is selected (“Yes”), it is energised when the pool is
being loaded.

6. Messages
In the case of a sensor fault, an error message is generated:
Sensor defective.
Furthermore, the defective sensor will be recognised (ab-
sorber sensor, pool sensor or flow temperature sensor).
Sensor fault
! Sensor faulty
> Absorber
Signal relay (error message)
Expert/Options/Signal relay
This function is switched on (option WMZ), when the
controller detects a fault. In this case, the signal relay is
energized (e.g. for signal lights).
These errors are:
• sensor defective
• pump defective
• real-time-clock (RTC) defective
• storage module (EEPROM) defective
Please note that a message caused by one of the plausibility
controls does not activate the relay.

Reset:
Expert/Options/Reset
selection: “Yes” or “No”.
The reset option can be selected. When the reset option is
selected (“Yes”), the controller settings are set back to the
factory settings.
