5.2 LIMITING BOILER MAXIMUM OUTPUT

The boiler is supplied for operation on maximum heat output of 15kW. The output can be rated below this maximum to
match the heat load required. This rating is done by means of P03 parameter. See above”5.1 INSTALLATION

PARAMETERS”

WARNING

: ON INSTALLATIONS WHERE THE INCOMING POWER SUPPLY IS NOT CAPABLE OF

MAXIMUM LOAD THE BOILER CONTROL MUST BE RE-CONFIGURED TO LIMIT THE OUTPUT BEFORE SWITCHING
ON.
As the output for Domestic Hot Water will also be limited to the same level it is recommended to adjust to the highest
output possible so as to maintain the best hot water performance.

The boiler will not exceed this pre-set maximum but will still modulate in heating mode up to this level, adapting to demand
and ensuring economic operation.
Correct configuration for the selected output can be checked on the boiler display panel following the procedure shown in
7.4 CHECKING RATED HEAT OUTPUT.

CAUTION: It is essential to confirm the power output with the use of a clamp meter.
