5.5.1.1 Changing the value of the K
t
coefficient
When the weather function is active (outside temperature sensor is connected), while changing parameter values in the C.H.
setting, the value of the K
t
parameter is displayed instead of temperature. For example, displaying 5.2 without C
5.5.1.2 Changing the ECO factor
If the boiler is equipped with an adjustable speed pump, you can change the value of the ECO factor. (section 2.4.5),
In WINTER operation mode, hold the + / - button for 2 seconds. The symbol ‘Ec’ will appear flashing on the left side while the
ECO factor value (e.g., 0.5) will appear flashing on the right side. Use the + / - buttons to change the ECO factor parameter
value. Exit of “parameter change mode” happens automatically after 3 seconds of inactivity or after pushing the reset button.
5.5.2 Temperature settings in the DHW circuit
1.
Briefly press the b / - to enter the DHW mode. The DHW temperature will be flashing on the left side of the
display.
2.
Use the b/- to adjust the DHW parameter values
3.
The DHW mode will exit automatically after 5 seconds of inactivity or after pressing the reset button.
NOTE!
1.
Reducing the set parameter values for heating water in the DHW circuit to a value less than that indicated on the display
by symbol ”MIN” will stop the water heating process in the tank. On the left field of the controller display, the symbol “—”
will be seen. To resume water heating in the tank, ensure the DHW settings are at the minimum values or higher.
2.
When the controller is in STANDBY mode, service function mode, or in the emergency lock out state, the C.H. or DHW
settings cannot be changed.
