DESCRIPTION OF INDICATOR SYMBOLS
–
during controller operation
- the current heat storage tank temperature is displayed
- the current collector temperature is displayed
- the pump is operating
- the pump is operating regardless of temperature
CONTROLLER OPERATION
The controller makes it possible to switch between two pump operation modes: automatic and
continuous. The default setting is the automatic mode. The user is able to manually switch on/off the
continuous mode of pump operation by pressing the
START
(
+
) and
STOP
(
-
) buttons.
1. automatic operation mode:
- the controller activates the pump at full capacity if the collector temperature is higher than the storage
tank temperature by the preset parameter
“activation delta” (
). If the difference in temperatures
decreases, the pump slows down its operation until it stops completely after reaching the preset
parameter
“inactivation delta” (
);
- the heat storage tank is heated until it reaches the temperature set by the user;
- when the pump is activated, the indicator light
is lit.
2. continuous operation mode:
- the pump operates regardless of the temperature (e.g. to check pump operation);
- the indicator light
is lit.
Note: After controller connection to the mains supply, the pump always operates in the automatic
mode.
The controller can protect the heat storage tank from overheating
–
STORAGE TANK PROTECTION
.
In this case, the controller activates the pump if the temperature of the heat storage tank exceeds the
preset temperature by the value of the
STORAGE TANK PROTECTION
parameter and the collector
is at least
10°C cooler than the storage tank.
The controller can activate the pump in the emergency procedur
e if the collector’s temperature
exceeds 99°C despite the preset temperature of the heat storage tank being exceeded –
STORAGE
TANK PROTECTION
from overheating.
CHANGE OF DISPLAYED TEMPERATURE
The controller makes it possible to monitor temperatures measured by both sensors. Switching between
displayed temperatures can be performed by pressing the
MENU
button. The
and
indicators
show which of the temperatures is currently displayed.
