control module;
1.
In case the burner
is mounted to hot
water boiler and
the
room
temperature is low
Low assigned
temperature of the
room thermostat (if

correct working order of the system burner-
appliance and its eventual re-adjustment of
the operation parameters – to be performed
by specialist. After cooling of the consuming
appliance and removal of the failure the
emergency thermostat has to be deactivated
(unscrew the protection cover, press the
