Load monitor
EcoEl has a load monitor. If the supplied current sensor is fitted, the house’s main fuses
are continuously monitored to ensure they are not overloaded. If the fuses are overload-
ed, an electrical step is disconnected from EcoEl. The heat pump can be limited where
high heating requirement levels are combined with (for example) single phase engine
heaters, cookers, washing machines or tumble dryers. This can result in inadequate
heating or hot water temperatures.
If the heat pump is limited,
High electrical output, reduced electri-
cal power (X A)
is displayed in text in the display.
Consult an electrician to determine whether the fuse size is correct.
Air problem
If a chafing sound is heard from the heat pump, check that it is fully bled. Turn the
boiler safety valve so that any air can be evacuated. Add water where required, so that
the correct pressure is achieved. If this occurs repeatedly, call a technician to check the
system.
!
Do not forgot that
the radiators may
also need to be bled.
