Commissioning
NOTICE
NEVER operate the unit without thermistors and/or
pressure sensors/switches. Burning of the compressor
might result.
INFORMATION
The software is equipped with an "installer-on-site" mode
([9.G]:
Disable protections
), that disables automatic
operation by the unit. At first installation, setting
Disable
protections
is by default set to
Yes
, meaning automatic
operation is disabled. All protective functions are then
disabled. If the user interface home pages are off, the unit
will NOT operate automatically. To enable automatic
operation and the protective functions, set
Disable
protections
to
No
.
36 hours after the first power-on, the unit will automatically
set
Disable protections
to
No
, ending "installer-on-site"
mode and enabling the protective functions. If – after first
installation – the installer returns to the site, the installer
has to set
Disable protections
to
Yes
manually.
6.1
Checklist before commissioning
After the installation of the unit, first check the following items. Once
all below checks are fulfilled, the unit MUST be closed, ONLY then
can the unit be powered up.

applicable)
The system is properly
earthed
and the earth terminals
are tightened.
The
fuses
or locally installed protection devices are

or
squeezed
pipes
on the inside of the indoor and outdoor units.

water leak
inside the indoor unit.
The
shut-off valves
are properly installed and fully open.
The

The
air purge
valve is open (at least 2 turns).
The
pressure relief valve
purges water when opened.
The
domestic hot water tank
is filled completely.
6.2
Checklist during commissioning
The
minimum flow rate
during backup heater/defrost
operation is guaranteed in all conditions. See "To check
the water volume and flow rate" in
To perform an
air purge
.
To perform a
test run
.
To perform an
actuator test run
.
Underfloor screed dryout function
The underfloor screed dryout function is started (if
necessary).
6.2.1
To check the minimum flow rate
Mandatory procedure for the additional zone
1
Confirm according to the hydraulic configuration
which space heating loops can be closed due to
mechanical, electronic, or other valves.
—
2
Close all space heating loops that can be closed
(see previous step).
—
3
Start the pump test run operation (see
perform an actuator test run" on page 25
—
4
During pump test run operation, go to
Sensors
.
5
Select the flow rate information. During test run
operation, the unit can operate below the minimum
required flow rate.
6
Modify the bypass valve setting to reach the
minimum required flow rate + 2 l/min.
—
Recommended procedure for the main zone
INFORMATION
The pump of the additional zone ensures that the minimum
flow rate for correct operation of the unit is guaranteed.
1
Confirm according to the hydraulic configuration
which space heating loops can be closed due to
mechanical, electronic, or other valves.
—
2
Close all space heating loops that can be closed
(see previous step).
—
3
Create a thermo request on the main zone only.
—
4
Wait 1 minute until the unit is stabilized.
—
5
If the additional pump is still assisting (the green
LED on the right hand sided pump is ON) increase
the flow until the additional pump is not assisting
anymore (LED is OFF).
—
6
Go to [8.4.A]:
