Energy return hysteresis -
Option available only for schemes 5, 11. When the energy return threshold
temperature is reached, the valve switches to the CH boiler return circulation. The valve will switch again after
the tank cools down by the value of the energy return hysteresis.
•
Solar pump energy return -
Option available only for schemes 5, 11. Schemes 5 and 11 enable the user to
deactivate the solar pump, e.g. to cool down the tank using the auxiliary pump.
•
Heating deactivation -
Option available only for scheme 10. In this configuration the tank is heated with a dual
function boiler. Heating deactivation concerns the threshold temperature which the tank can reach while heating
–
if the tank temperature exceeds this value, heating with the use of dual function boiler is deactivated (valve
switching).
•
Activation delta (return)
- Option available only for scheme 11. This parameter determines the maximum
difference between the tank temperature and the CH boiler return circulation temperature at which the valve
switches to heating the CH boiler return.
•
Deactivation delta (return)
- Option available only for scheme 11. This parameter determines the minimum
difference between the tank temperature and the boiler return circulation temperature at which the valve
switches to standard boiler circulation (without heating).
•
Valve delta
–
In this configuration the regulator controls the switching valve. If the temperature of the upper
tank sensor is higher than the valve temperature plus the value of the valve delta, the valve switches the
circulation to the bottom part of the tank. The circulation will be switched to the upper part again when these
temperatures become equal.

ALARM SOUND
This function enables the user to activate/deactivate the sound signal after an alarm occurs
.

FACTORY SETTINGS
The controller is pre-configured for operation. However, the settings should be customized to the user's needs. Return to
factory settings is possible at any time. Once the factory settings option is activated, all customized settings of the solar
installation controller (saved in the user's menu) are lost and replaced with the manufacturer's settings. Then, the
parameters may be customized anew. Return to factory settings results in activating the default installation scheme.

EDIT SERVICE CODE
It is possible to edit service menu code. Go to this submenu, enter the code and confirm the settings.
