Function

ATTENTION!
This device is not intended for use by persons, including children, with
restricted physical, sensory or mental abilities or who lack the necessary
knowledge or experience, except under the supervision of a person
responsible for their safety or unless they have been instructed by this
person as to how the device is to be used. Children must be supervised
to ensure that they do not play with the device.
The CTHK 630 to CTHK 636 screw-in heaters can be installed in
heating system buffer tanks and domestic hot water cylinders
(PWD according to the flow principle).
necessary when electronic screw-in heaters are used as main
heaters or for supplementary heating for (electrically) heated
cylinders. In the case of very hard water, periodic cleaning of the
heating elements to remove limescale is recommended.
The user can pre-select the desired maximum temperature on
the rotary controller. During the heat-up time (determined by the
utility company responsible), the heating is automatically
switched on and - after reaching the desired temperature in the
water cylinder - switched off again by the temperature controller
(or the controller of the heat generator). If the water temperature
drops, e.g. due to a heating request or natural cooling, the screw-
in heater will be switched on automatically until the pre-selected
water cylinder temperature is reached.

Energy saving

The lower the cylinder water temperature selected, the more
economical the heat generation. The infinitely adjustable
temperature should therefore only be set as high as is needed for
the actual hot water or cylinder water requirement. As a positive
side effect, this not only saves electrical energy, but can also
prevent the formation of limescale deposits inside the cylinder to
the greatest possible extent! In combination with the heat pump
manager (WPM) it is also possible to prevent unnecessary
switching-on of the screw-in heater by setting the limit
temperature (bivalence point).

Operation and
temperature setting
Depending on your water requirement, you can set the water
temperature inside the cylinder freely with the temperature
selector or by using the marked main heating levels. This
provides for an energy-efficient operation of the screw-in heater
according to need!
NOTE
When the screw-in heater is controlled via the heat pump manager, the
supplementary electric heating system must be set to the max.
permissible flow temperature of the heat pump using the rotary
controller!

As an adjustment aid, four main levels are marked on the
temperature control knob:
Position:
Frost protection for the cylinder
Position:
Approx. 40°C, hand-hot water from the cylinder (recommended
for heating living spaces with underfloor heating).
Position:
Approx. 60°C, moderately hot water from the cylinder. This
setting is recommended for heating living spaces with radiators
to prevent the water temperature in the cylinder from getting too
No maintenance is
high.
The device operates particularly efficiently at this setting. Heat
losses are low, and the formation of limescale is largely
prevented.
Low stand-by energy consumption!
Position:
Approx. 80°C, hot water from the cylinder (for older radiators with
high flow temperatures only).
The control knob being at the left end-stop does not mean "zero"
position, nor does it result in the device heating switching off.
If the system is operated with day current, we recommend setting
the temperature controller no higher than oo (approx. 60°C).

Screw-in heaters can only be used under the conditions listed on
the power rating plate (operating pressure, heating-up period,
connection voltage). The electrical connection must be made
according to the connection diagram attached to the inside of the
dust cap.
In addition to the national legal regulations (VDE and/or DIN EN,
etc.) the user must also comply with the connection requirements
of the local power and water supply companies and follow the
installation and operating instructions.
All screw-in heaters are suitable for pressure-resistant operation
and for the heating of heating water up to a maximum operating
pressure of 10 bar.
In the case of very hard water, it is recommend that a standard
decalcifying device is installed upstream in the circuit.
The screw-in heaters are suitable for integration into floor-
mounted cylinders and devices with dual cladding. Thanks to
their special design, the devices can also be installed in third-
party produced systems with enamelled, plastic-coated or hot-
dip galvanised boilers. A combination with CrNi (stainless steel)
boilers may cause problems and is therefore not recommended.
