Technical features and dimensions
ENGLISH
The panel board of the XC-K boiler automatically switches the
burner off when the temperature in the boiler reaches the value
set on the heating controller.
It also manages the pump to fill a storage tank for DHW
production.
The heating systems are managed automatically based on the
data detected by the boiler, external, ambient and flow probes.
The high temperature zone system pump is made ready for ope-
ration by the control switch pos. 20, and will only switch off when
the temperature set on the heating controller has been reached.
The low temperature zone system pump is made ready for ope-
ration by the control switch pos. 21, and will only switch off when
the temperature set on the heating controller has been reached.
The storage tank charge pump for DHW production switches on
automatically and will only switch off when the temperature set
on the heating controller has been reached.
The panel is set up to manage the modulating burners.
With this system configuration, the heat controller is capable
of regulating:
- direct zone system; the control unit commands the
system pump. The room temperature is controlled by
the programming curves set in the heating controller;
- one zone system with motorised mixer valve: the flow
probe (downstream the mixer valve) must be fitted; the
control unit commands the system pump and the mixer
valve. The room temperature is controlled by the
programming curves set in the heating controller;
- DHW production through storage tank;
- anti-legionella function with increase of water
temperature in storage tank (function not enabled in
factory, but can be enabled by customer)
