2 INSTRUCTIONS FOR THE END USER
11
2.1 Controlling the device and heating system
Use the device and heating system in accordance with this manual and instructions for use
of the heat pump which explains the use off the device and heating system.
2.2 Maintaining the device and heating system
The device must be visually inspected once a year. The electrical and hardware installation
of the device have to be inspected. In the case of detected irregularities, contact the
authorised technician.
CAUTION
The servicing and maintenance of the device can only be performed by a person
authorised by the manufacturer. In case of a malfunction, first contact the installer
who installed the device.
NOTE
Cleaning of water filters on the return into the device is advised to be performed at
least once yearly.
CAUTION
A blocked water purifying component and magnetic filter can lead to a malfunction
of the device or incorrect functioning of the device. In case the display displays a
warning of flow malfunction (”Caution, flow!”).
NOTE
Periodically, once yearly, check the water temperature in the heating system.
NOTE
In case the pressure falls (i.e. Leakage of the system) the display displays a
warning of flow malfunction (”Caution, flow!”).
2.2.1 OPERATION MALFUNCTIONS
In case of a malfunction during the operation of the device, the display of the
TERMOTRONIC controller displays the warning “Caution, malfunction”.
Find the malfunction description in the “Owner’s manual”. For error correction call the
installer who installed the device.
2.2.1.1 Resetting the thermal protection of the built-in electrical
heater
The thermal protection of the electrical heater is an additional safeguard protecting the
device in the following cases:
12
The electrical contactor which turns on the electrical flow heater can be
permanently short-circuited.
At commission, air is in the system, which causes heating without heat extraction.
The easiest way to determine whether the thermal protection of the electrical heater is
turned off is to turn on the operation of the auxiliary source on the TERMOTRONIC control
unit. If the electric heater is operational, the water temperature in the heating system will
start to rise.
In case the electrical heater does not work because of one of the before mentioned
reasons, the safety thermostat has to be reset after the problem is resolved. It is reset by
pushing the red button. If the reset is successful, you will hear a “CLICK”.
