Commissioning and adjusting
Circulation pump
Pump speed
The circulation pump in HM 6Split / HM 12Split is fre-
quency-controlled and adjusts itself using control and
based on heating / hot water demand.
Pressure available, circulation pump GP12.
Post-adjustment, venting
Initially, air is released from the heating medium and
venting may be necessary. If gurgling sounds can be
heard from the climate system, the entire system will
require additional venting. The system is vented via the
vent valves. During venting, HM 6Split / HM 12Split
must be switched off.
Commissioning
CAUTION
Commissioning of the system must be carried out by
a person with appropriate authorizations and manufac-
turer’s authorization!
For commissioning of the heat pump:
1. Switch on the power supply to HM 6Split / HM
12Split making sure that the L Split unit is proper-
ly connected to the power supply.
2. Follow the instructions displayed in the controller
start guide or alternatively start the start guide in
menu 5.7.
Commissioning
Start Guide
CAUTION
The climate system must be filled with water and vented
before setting the switch to “I“.
The first time the system is started up, a start guide
is launched. The start guide instructions state what
needs to carried out at the first start-up together with
a run through of the system’s basic settings.
The start guide ensures that start-up is carried out
correctly; it cannot be bypassed. The start guide can
be started later in menu 5.7.
During the start guide, the reversing valves are opera-
tional in order to help vent the heat pump.
1. Set the switch (SF1) on the controller to “
I
”.
2. Follow the instructions in the display’s start
guide. If the start guide does not start when you
start the controller, start it manually in menu 5.7.
TIP
See page 35 for more in-depth information on the in-
stallation’s control system [1](operation, menus etc.).
NOTE
As long as the start guide is active, no function in the
controller will start automatically.
The guide will appear at each controller restart until it
is disabled on the last page.
NOTE
If starting up the system in low outdoor temperatures
and a low heating medium temperature in the central
heating system, the central heating system should be
warmed up first, using the additional heat, to a tem-
perature of about 20 -25 °C.
