General Comments
Take into account that all hot water taps are carefuly closed. The boiler
gives priority to hot water instead of the central heating. When there
is a leaking hot water tap, the boiler will switch off the central heating.
The frequency of maintenance
We advise that an inspection of the boiler is carried out every two years
and an overhaul every four years. When doing this the circumstances
of the boiler’s location and current gas safety regulations must be
taken into account. From this one can determine whether to deviate
from this advice.
i.e. Error indication (with a flashing number in the third and
fourth display position)
short-circuit of 24 volt circuit
no flame-forming
maximum supply temperature exceeded
Water pressure is too low (<1,0 bar), flashing FILL will be
altered with indication of water pressure, unit power of 50% is
possible. The installation needs to be topped up.
Water pressure is too low (<0,7 bar), FILL indication remains
continuously visible, the unit is taken out of operation. The
installation needs to be topped up.
Water pressure is too high (>3,5 bar), HIGH indication
remains continuously visible, the unit is taken out of opera-tion.
The installation pressure needs to be decreased by draining
water.
When detected, errors are indicated on the display. Some, of a
temporary nature, will not usually result in the boiler locking out. Whilst
the control system will try its utmost to prevent lockout, and may
temporarily switch off the unit, any fault which could potentially damage
the appliance will result in lockout. There are two categories - i.e.
Blocks and Errors.
