When the checks are completed:
- set the boiler to HOT WATER ONLY or HEATING AND HOT WATER
mode depending on the season
- regulate the heat request temperature values according to the customer's
needs.
IMPORTANT
The combustion analysis function is active for a time limit of 15 minutes;
the burner shuts down if an outlet temperature of 95° C is reached. It will
ignite again when the temperature falls below 75° C.
b
In case of a low temperature system we recommend carrying out the
efficiency test by taking hot water setting the boiler STATE to HOT
WATER ONLY, opening the hot water tap to full capacity and setting
the temperature of the domestic hot water to the maximum.
b
All controls must be carried out exclusively by the Technical
Assistance Centre.
