7.6 Installation and commissioning certificate
Note!
The installation and commissioning certificate can be found at the end
of the operating manual.
8 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
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.
8.2 Variomat switching points
The "P
0
" 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
0
" minimum operating pressure.
The "P
0
" minimum operating pressure is calculated as follows:
P
0
= P
st
+ P
D
+ 0.2 bar*
Enter the calculated value in the start routine
of the controller, 8.3 "Modifying the
controller's start routine", 40.

= 0.0 bar for safety temperatures ≤ 100 °C

*Addition of 0.2 bar recommended, no addition in extreme cases
Note!
Avoid dropping below the "P
0
"minimum operating pressure. Vacuum,
vaporisation and cavitation are thus excluded.
8.3 Modifying the controller's start routine
Note!
For handling the operator panel
10.1 "Operator panel", 43
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.

The system automatically displays the first page of the start routine when you
switch on the device for the first time:
1. Press "OK“.
– The start routine moves to the next page.
2. Select the required language and conform your entry with "OK".
