Principle of operation
EVC 13 has an outdoor temperature controlled boiler
temperature which is why a shunt valve is not re-
quired. The outside temperature sensor is supplied.
The output is connected and disconnected with the
help of two contactors and two relays. EVC 13 has an
integrated circulation pump, expansion vessel, safety
valve, tapping valve, load monitor and an input for
centralised load control. Current regulations require
the heating installation to be inspected before it is
commissioned. The inspection must be carried out by
a suitably qualified person and should be document-
ed. The above applies to electric boilers with a closed
expansion vessel. The installation must be inspected
again if the boiler or the expansion vessel are re-
placed.
