1. FUNCTION
The electric built-in heaters are service and maintenance-free as the main heating unit for electrically heated hot
water tanks. Only in the case of heavily calciferous water it may be necessary to free the heating units from boiler
scale in certain intervals.
The desired temperature can be selected by the user on the control toggle. The heating is switched on automa-
tically by the temperature control, during the heating period determined by the relevant ESC, and off again when
the desired tank water temperature is reached. If the water temperature drops, e.g. by the withdrawal of water
or natural cooling-off, then the device heating switches on again until the pre-selected tank water temperature
is reached.
2. ENERGY SAVING
Low tank water temperatures prove to be particularly economical. Therefore, the progressively adjustable temperature
should only be selected as high as necessary for the actual hot water demand. This helps to save electricity and reduces
furring in the tank.
3. OPERATION AND TEMPERATURE SETTING
The tank water temperature can be set progressively using the temperature selector or by the four indicated main grades
in accordance with your hot water demand. This way, an energy-conscious operation of the built-in heater is possible:
As a setting aid, the toggle of the electric heater's temperature control has 4 indicated main stages, namely:
Position:
frost protection for the tank (up to 30 °C)
Position:
approx. 40°C, hand warm tank water
Position: ••
approx. 65°C, moderately hot tank water
This position is recommended to rule out unintentional scalding by excessively hot water.
The device operates particularly economically in this setting.
The heat losses are minor and the formation of boiler scale is largely avoided.
Low standby energy consumption.
Position: •••
approx. 75°C, hot storage water, (temperature controller up to 80°C optionally available)
Caution:
Control toggle at left limit stop does not result in an off position or shutdown of the device heating.
The temperature control should not be set higher than the position •• (approx. 65°C) when operated using day current.
Due to the hysteresis of the temperature control (± 7°K) and possible radiation losses (cooling-down of the pipelines), the
temperature specifications are subject to an accuracy of ± 10°K.
4. OPERATING REQUIREMENTS
The built-in heating must be used exclusively in accordance with the requirements (operating pressure, heating time, supply
voltage, etc.) specified on the rating plate. The power connection must be performed in accordance with the connection
diagram affixed to the inside of the protective cap.
In addition to the legally approved national regulations (ÖVE, VDE, ÖNORM or DIN, etc.), the connecting requirements of
the local power company and waterworks as well as the Assembly and Operating Instructions must also be complied with.
In the case of heavily calciferous water, we recommend the upstream integration of a customary antiliming device.
This built-in heater is particularly suitable for installation in enamelled free-standing tanks as well as double shell units.
Due to the special design, however, these units may also be installed in foreign makes with enamelled, plastic-coated or
hot-dip galvanised boilers. A combination with CrNi (NIRO) boilers is problematic and therefore not recommended (for
necessary measures see section 5.3).
For the purpose of installation in enamelled boilers, our built-in heaters, screw-mounted heating units and built-in finned
tube heat exchangers are designed using structurally isolated heating units in conjunction with a guard circuit shunt resistor
and are therefore in compliance with the state of the art, particularly with regard to the corrosion protection of enamelled
boilers. All heating installations are suitable for pressure-proof operation and the heating up of drinking or heating water up
to a maximum operating pressure of 10 bar.
This device is not designed to be used by persons (including children) with physical, sensory or mental disabilities or lacking
experience and/or lacking knowledge, unless these are supervised by a person who is responsible for their safety or have
received instructions on how to use this device from any such person. Children should be supervised in order to ensure
that they do not play with this device.
Built-in heating systems are not suitable for use in aggressive media (alcohol, glycol, oil, etc.)!
