7 Commissioning
Note!
Confirm that installation and start
-up have been carried out correctly using the installation, start-up and maintenance
certificate. This action is a prerequisite for the
making of warranty claims.
Have the Reflex Customer Service carry out commissioning and the annual maintenance.
7.1 Requirements for initial commissioning
The device will be ready for commissioning when the tasks described in the "Installation" chapter have been completed.
• The device is fully connected to the facility.
– Fillcontrol Auto 2P
• Make-up line to the system
– Fillcontrol Auto 2PS
• Make-up and degassing lines to the facility system.
• Water make-up supply from the fresh-water system is created.
• The connection lines of the device have been flushed and cleaned of welding residue and dirt, if required, before commissioning.
• The facility system is filled with water and roughly gas-vented.
– The circulation through the ensure facility system is ensured.
• The electrical connection has been created according to applicable national and local regulations.
7.2 Determining the P
0
minimum operating pressure for the controller
Calculate the "P
0
“ minimum operating pressure. During the start routine of the controller, enter the value for the minimum operating
pressure. The controller uses the minimum operating pressure to calculate the required filling pressure for water make-up into the
facility system.
The value for the minimum operating pressure depends on the hydrostatic pressure "p
st
“ and the static height in the facility system. The
static height "h
st
" is the difference (in metres) from the highest point of the facility system to the connection of the diaphragm expansion
tank.
Value examples:
• Heating system: Static height h
st
= 18 m, flow temperature 70 °C, safety temperature 100 °C.
• Boiling pressure p
D
= 0 bar (at a safety temperature of 100 °C
– For safety temperatures 110 °C p
D
= 0.5 bar
• *Addition of 0.2 bar recommended, no addition in extreme cases
Calculating the "P
0
" minimum operating pressure:
1. Calculate the hydrostatic pressure "p
st
" from the static height "h
st
of the facility system.
p
st
=
ℎ
10
=
18
10
= 1.8 bar
2. Use the hydrostatic pressure to calculate the minimum operating pressure "P
0
" for the facility system.
P
0
= p
st
+ p
D
+ 0.2 bar*
P
0
= 1.8 bar + 0 bar + 0.2 bar = 2.0 bar
3. During the start routine of the controller, enter the value for the minimum operating pressure "P
0
“, see chapter 7.4 "Modifying the
controller's start routine" on page 31 .
