site)

Install EMERGENCY OFF switch

Austria: Firing systems for which a heating room is
required must be equipped with an EMERGENCY
OFF switch, which must not have an effect on the
room lighting. It must be situated immediately outside
the access door and labelled clearly and visibly. This
switch may also be located inside the heating rooms,
immediately next to the access doors, but only if the
heating rooms can be accessed from outdoors.

►

Integrate the emergency stop switch into the
safety chain of the boiler, connection

X6.1-X6.8

►

Connect other components integrated in the
safety chain in series ("loop through")

Pellet delivery system (A1:X14)

(these systems have a motor–thermal pro-

tection is integrated).

►

Use 3x1,5 mm² cable

►

Bridge the two TK terminals on the boiler power
element.

External boiler request (A1:X28)

Potential-free Relay output for switching an external
boiler, for example, an external boiler is controlled by
the SOLARFOCUS boiler control
