Controller Installation and Commissioning

Mounting
NOTE! Any electrical connections must be made by duly authorised and qualified persons
after power supply has been disconnected!
1. Hang the controller on the fitting bolt (using the opening at the back of the housing).
2. Remove the connection cover and fix the controller to the wall with additional bolts.
3. Connect the panel temperature sensor to terminals 1,2. Place the sensor bit in the
measuring point in the collector.
4. Connect the tank sensors to appropriate terminals as shown in the diagram. Place
the sensor bits in relevant temperature measuring points.
5. Ensure good thermal contact between the sensor and the sleeve. If necessary, use
thermal grease.
6. Connect P1 pump to terminals 15,16.
7. Connect P2 pump to terminals 13,14. Connect the electric heating coil via an
additional contactor whose coil will be supplied from terminals 13, 14.
8. Connect the earth wires using the controller's bottom terminal strip.
9. Replace the controller cover.

Tank loading
If the temperature difference between the solar panel and the tank (T1-T2) exceeds
, the controller will switch on the tank loading pump (pump symbol displayed) at full
speed. If the temperature difference drops below the set parameter, the controller will
reduce the pump's speed. If, despite the reduced speed, T1-T2 temperature difference
drops below , the pump will be switched off. It can be switched on again only after
the temperature difference (T1-T2) exceeds
The loading of the tank stops when tank temperature T2 exceeds
temperature difference between the panel and the tank (T1-T2) is big enough for the pump
to run.
Basic settings
Set temperature of DHW tank. If the tank temperature (T2 or T3)
exceeds this value, the loading stops.
T1-T2 difference; when exceeded, the tank loading pump is switched
on.
If T1-T2 difference drops below this value, the tank loading pump will
switch off.
Enabling of a sound alarm.
0 – sound alarm disabled, 1 – sound alarm enabled.
