REMKO
ELECTRIC BOOSTER HEATER WITH EMERGENCY
HEATING MODE FOR HEAT PUMP INDOOR UNITS
Operation
In order to operate the electric booster
heater in an economical and energy-
saving manner, you should set the supply
water temperatures as low as possible.
Only set the infinitely variable temperature
to the level you need for the actual water
temperature. This saves energy and reduces
the buildup of limescale in the container.
Depending on the water supply
temperature, the thermostat control can
be used to set the temperature to the
marked points on an infinitely variable
basis.
When operating with day current,
the temperature control should not
be set any higher than on setting
(approx. 65°C).
NOTE
! ATTENTION
The thermostat control's left stop
position does not represent a zero or
shutdown setting for the unit heater!
Due to the hysteresis of the temperature
control (±7°K) and possible radiation
losses (cooling down of the pipes),
the temperature data is subject to an
accuracy of ±10°K.
The temperatures are set using the
thermostat control on the heating coil
- Storage water at approx. 40°C,
warm to the touch
- Storage water at approx. 65°C,
moderately hot
In order to avoid scalding
with excessively hot water, this
setting is recommended
ajar. It causes the unit to
work particularly economically.
Heat losses are low, and the buildup
of limescale is largely avoided.
There is only a low standby
energy consumption.
- Storage water at approx. 85°C, hot

Scope of delivery
If the water temperature falls, e.g. due to
extremely low outside temperatures, then
the unit's heater switches back on until
the set water temperature is reached.
Thanks to the inclusion of an
“emergency switch”, an additional
3 kW can be activated manually, for
a total of 9 kW of heating power.
