9.4 Switching DHW comfort function on and o
It is possible to switch on and o the DHW comfort function
from an OpenTherm room thermostat (provided the
thermostat supports this function). To do this, the boiler must
be set at the ‘eco’ setting and the parameter P074 must be
set to 0. The self-learning character of the control is therefore
switched o. (See section §8.4 for further options).

The maximum central heating output is factory-set. If this
needs to be adjusted to suit the requirements of the property,
then the output can be modified via parameter P010.
See the table below:
Setting central heating output.
The Xclusive boiler has an ErP pump that modulates based on
the central heating output demand. The minimum and
maximum output of the pump can be adjusted with the
parameters P031 and P032. See section §9.3.
The set value of parameter P031 (max. pump setting) is a
percentage of the maximum pump capacity and is linked to
parameter P010 maximum central heating system output.
The set value of parameter P032 (min. pump setting) is linked
to the minimum central heating output.
The pump capacity must be set so that the temperature
dierencial (t) between the flow and return is correct for the
system design criteria.
If the central heating load modulates between the minimum
and maximum value, the pump capacity will modulate
proportionately with it.
