Safety instructions
All electrical work shall be carried out
exclusively by licensed electricians.
When installing or repairing electrical
equipment, always be sure that it is
completely isolated from the supply. Do
not work on live parts.
Install the controller in a dry room and
at a location where it is not exposed to
temperatures > 50°C.
Temperatures can reach as high as
90°C in the connected storage tanks.
As a result, boiling protection must be
provided for domestic hot water storage
tanks (
Heizungsanlagenverordnung
Section 8, Clause 2 (heating systems
directive).
The supplied wall-mount enclosure
shall only be used for a stationary in-
stallation.
Product description

Installation
The assembly and initial start-up
shall be done exclusively by author-
ized professionals who assume
responsibility for proper installation
and start-up.
Following initial startup, the opera-
tor will be given instructions regard-
ing user-related features of the con-
troller.
This training is the responsibility of
the authorized professional in-
staller.
