ALHENA C
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the required temperature in the rooms. The boiler will adjust
the system water according to the required room temperature. For operation with remote timer
control, please refer to the relevant instruction manual.
ECO/COMFORT selection
The unit has a function that ensures a high domestic hot water delivery speed and maximum
comfort for the user. When the device is activated (COMFORT mode), the water contained in the
boiler is kept hot, therefore ensuring immediate availability of hot water on opening the faucet,
without waiting times.
The device can be deactivated by the user (ECO mode) by pressing the winter/summer/off but-
ton (detail 7 - fig. 1) for 5 seconds. In ECO mode the display activates the ECO symbol (detail 12
- fig. 1). To activate the COMFORT mode, press the winter/summer/off button again (detail 7 -
fig. 1) for 5 seconds.
Sliding Temperature
When the external probe (optional) is installed, the boiler adjustment system works with "Sliding
Temperature". In this mode, the heating system temperature is regulated according to weather
conditions, to ensure high comfort and energy efficiency throughout the year. In particular, as the
outside temperature increases the system flow temperature decreases according to a specific
"compensation curve".
With "Sliding Temperature", the temperature set using the heating buttons (details 3 and 4 -
fig. 1) becomes the maximum system flow temperature. It is advisable to set a maximum value to
allow system adjustment throughout its useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. However, the user
can make any further adjustments necessary to optimize comfort levels.
Compensation curve and curve offset
Press the reset button (detail 6 - fig. 1) for 5 seconds to access the "Sliding temperature" menu;
the display shows "CU" flashing.
Use the DHW buttons (detail 1 - fig. 1) to adjust the desired curve from 1 to 10 according to the
characteristic (fig. 13). By setting the curve to 0, the sliding temperature adjustment is disabled.
Press the heating buttons (detail 3 - fig. 1) to access parallel curve offset; the display shows "OF"
flashing. Use the DHW buttons (detail 1 - fig. 1) to adjust parallel curve offset according to the cha-
racteristic (fig. 14).
Press the heating buttons (detail 3 - fig. 1) to access the menu "shutdown for outside temperatu-
re"; the display shows "SH" flashing. Use the DHW buttons (detail 1 - fig. 1) to adjust the shutdown
outside temperature. If set to 0 the function is disabled; the range varies from 1 to 40°C. Lighting
occurs when the external probe temperature is 2°C lower than the set temperature.
Press the reset button again (detail 6 - fig. 1) for 5 seconds to exit the "Sliding Temperature" me-
nu.
