5 Commissioning the device for the first time
Danger
Risk of death by electrocution! Be sure to perform all the measures listed in section 4
before starting the first commissioning.
Notes
• After commissioning the controller for the first time, it is configured in such a man-
ner that it can be used in most applications without changes.
• After completing the first commissioning, later recommissioning is not necessary.
• The following steps must also be performed after the device has been reset to the
factory settings.

The first time the controller is switched on, the follow-
ing settings are made via a guided configuration process
(Fig. left):
• Time
• System (hydraulic variant)
• Type (Standard/high-efficiency pump) and minimum
speed of the connected pumps (not System 0.1)
• Functions
Values can be changed later within the guided configura-
tion process. The following applies:
• /ESC/ navigate blockwise forwards and back-
wards
(Fig. left:  = forwards; ESC/ = back).
• Navigation (with /ESC/) is always possible after
completion of a block.
• Later modification of a block is initiated using the
SET button.
