In the course of the general annual maintenance of your heating system you
should also have the functions of the controller checked by a specialist and have
the settings optimised if necessary.
Performing maintenance:
- Check the date and time (see menu 3.1)
- Assess/check plausibility of statistics (see menu 2)
- Check the error memory (see menu 2.6)
- Verify/check plausibility of the current measurement values (see menu 1)
- Check the switch outputs/consumers in manual mode (see menu 4.2)
- Poss. optimise the parameter settings

If the controller detects a malfunction, the
red light fl ashes and the warning symbol also
appears in the display. If the error is no longer
present, the warning symbol changes to an
info symbol and the red light no longer fl ashes.
To obtain more detailed information on the
error, press the key under the warning or info

Do not try to deal with this
yourself. Consult a specialist in the
event of an error!
Notes for the specialist:
Means that either the sensor, the
sensor input at the controller or the
connecting cable is/was defective.
(Resistance table on page 7)
The maximum heat circuit temperature
set in menu 5.4 was exceeded.
Means that the controller was restar-
ted, for example due to a power failure.

USEFUL NOTES / TIPS AND TRICKS
- The service values (see menu 11.) include not only current measurement va-
lues and operating states, but also all of the settings for the controller.Write
the service values down just once after commissioning has been successfully
completed.
- In the event of uncertainty as to the control response or malfunctions
the service values are a proven and successful method for remote diagnosis.
Write the service values down (see menu 11.) at the time that the suspected
malfunction occurs. Send the service value table by fax or e-mail with a brief
description of the error to the specialist or manufacturer.
- To protect against loss of data, record any statistics and data that are
particularly important to you (see menu 2.) at regular intervals.
