Regulations for installation

•
A clearance of at least 10 mm must be provided on all sides of the controller,
enabling the unit to emit the amount of heat produced during its operation. The
space should not be accessible and no objects should be placed there.
•
The controller is designed for mounting in a boiler control panel. Power to the
controller may be supplied only after it is completely fitted in the cutout. If this is not
observed, there is a risk of electric shock near the terminals and through the
cooling slots.
•
If the controller shall be mounted directly on the wall, a housing must be used to
provide protection against electric shock hazard. The housing must have a
sufficient number of cooling slots at the bottom and the top, allowing the controller
to emit the heat it produces.
•
The controller has been designed based on the guidelines of safety class 2 and
must therefore be mounted in compliance with these regulations.
•
The controller may not be exposed to dripping water.
•
Permissible ambient temperature:
