Function
Heat is extracted from the outside air
at temperatures ranging from +30 °C
to –20 °C by the heat exchanger
on the air side (evaporator).
Heating water is heated in the
heat exchanger on the water side
(condenser) to levels set at the
control unit (from +15 °C to +60 °C)
by heat from the electrical power
used by the compressor. At air
temperatures below approx. +7 °C,
the humidity in the air precipitates as
hoarfrost on the evaporator fins. Any
hoarfrost is automatically defrosted.
water created from this defrosting
collects in the defrost pan and is
drained off via a hose. the fan is
switched oFF and the heat pump
circuit is reversed to activate the
defrost cycle. the energy required for
defrosting is drawn from the heating
system. the heat pump automatically
reverts to heating mode at the end of
the defrost cycle.
Appliance description WPL 10 A
Compact version for external
installation. the metal enclosure is
zinc-plated and finished in pearl-
white stove enamel. the heat
pump drive unit is equipped with
a hermetically sealed compressor
with crankcase heater, condenser,
evaporator, safety equipment such
as a high/low pressure limiter, and
a frost protection facility. Heating
water up to 75 °C can flow through
the heat pump in idle mode. the
refrigerant used is r407C. the heat
pump is controlled via a bUs cable.
