Nibe EVC 13 User Manual

System description
General
EVC 13 has outdoor temperature controlled boiler temper-
ature, which is why a shunt valve is not needed. Outdoor
temperature sensor supplied. The power is connected and
disconnected using two contactors and two relays.
EVC 13 has an integrated circulation pump, expansion
vessel, safety valve, drain valve, load monitoring 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 documented.
The above applies to electric boilers with a closed expan-
sion vessel. If the boiler or the expansion vessel is replaced,
the installation must be inspected again.
