The circulation pump in SHK 200S / SHK 200S-6 is
controlled by frequency, and is automatically regulat-
ed via control and based on the heating demand.

Later regulation, venting
Initially, air is removed from hot water, and venting may
be necessary. If gurgling can be heard in the heating
system, the entire system needs additional venting.
The installation is vented through vents. When venting,
SHK 200S / SHK 200S-6 must be switched off.

IMPORTANT
There must be water in the climate system be-fore the
switch is set to „
I ”.
The fi rst time the installation is started a start guide is
started. The start guide instructions state what needs
to carried out at the fi rst start together with a run
through of the installation’s basic settings.
The start guide ensures that start-up is carried out
correctly and cannot be bypassed. The start guide
can be started later in menu 5.7.
During the start-up guide, the reversing valves and
the shunt are run back and forth to help vent the heat
pump.

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.

ler's start-up wizard or start the start-up wizard in
