BOILER CONTROLLER - SERVICE MENU
Press the heating buttons (details 3 and 4 - fig. 151) to increase or decrease the power (Minimum=0%, Maximum=100%).
By pressing the DHW “-” button (detail 1 - fig. 151), boiler output is immediately adjusted to minimum (0%).
Wait about 1 minute for stabilisation.
By pressing the DHW “+” button (detail 2 - fig. 151), boiler output is immediately adjusted to maximum (100%).
If the TEST mode is activated and enough hot water is drawn to activate the DHW mode, the boiler remains in TEST mode but the 3-way valve goes to DHW.
To deactivate the TEST mode, press the heating buttons simultaneously (details 3 and 4 - fig. 151) for 5 seconds.
The TEST mode is automatically disabled in any case after 15 minutes or on stopping of hot water drawing (if enough hot water is drawn to activate DHW mode).
Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see “10.1 Adjustments” on page 67). Press the heating buttons detail 3 - fig. 151 to increase or decre-
ase the power (min. = 00 - max. = 100). Press the reset button within 5 seconds and the max. power will remain that just set. Exit TEST mode (see “10.1 Adjustments”
on page 67).
