Commissioning
Note!
Confirm that installation and start-up have been carried out correctly
using the installation and commissioning certificate. This action is a
prerequisite for the making of warranty claims.
–
Have the Reflex Customer Service carry out commissioning and
the annual maintenance.
8.1
Checking the requirements for commissioning
The device will be ready for initial commissioning when the tasks described in
the "Installation" chapter have been completed. The system designer or an
assigned expert is responsible for carrying out the commissioning (e.g. by
Reflex's Customer Service). Commission the pressurisation system according to
the information in the corresponding installation manual. Note the following
information on initial commissioning:
•
The control unit is connected to the primary tank and the secondary tanks,
if provided.
•
The water connections of the tanks to the facility system are established.
•
The tanks are not filled with water.
•
The valves for emptying the tanks are open.
•
The facility system is filled with water and gas-vented.
•
The electrical connection has been created according to applicable
national and local regulations.

Variomat switching points
The "P
" minimum operating pressure is determined by the location of the

pressurisation. The controller calculates the switching points for the solenoid
valve "PV" and the pump "PU" from the "P

The start routine is used to set the parameters for device commissioning. It
commences with the first switching on of the controller and can only be set
once. The following parameter changes or checks are carried out from the
customer menu, 10.3 "Configuring settings in the controller", 44.
A three-digit PM code is assigned to the setting options.
