To check the water volume and flow rate
Minimum water volume
Check that the total water volume in the installation is minimum
10 litre for RHBH/X04+08 and 20 litre for RHBH/X11+16, the internal
water volume of the indoor unit NOT included.
NOTICE
Tilt the bottom side of the front panel upwards and remove it.
When circulation in each space heating loop is controlled
by remotely controlled valves, it is important that the
minimum water volume is guaranteed, even if all of the
valves are closed.
Minimum flow rate
Check that the minimum flow rate (required during defrost/backup
heater operation) in the installation is guaranteed in all conditions.
NOTICE
3
When circulation in each or certain space heating loop is
controlled by remotely controlled valves, it is important that
the minimum flow rate is guaranteed, even if all valves are
closed. In case the minimum flow rate cannot be reached,
a flow error 7H will be generated (no heating/operation).
Remove the accessories.

Connecting the water piping
4.4.1
To connect the water piping
NOTICE
Do NOT use excessive force when connecting the piping.
Deformation of the piping can cause malfunctioning of the
unit.
To facilitate service and maintenance, 2 shut­off valves are provided.
Mount the valves on the water inlet and on the water outlet. Mind
their position. Orientation of the integrated drain valves is important
for servicing.
1
Install the shut­off valves on the water pipes.
4
Fill the circuit with water until the manometer indicates a
pressure of ±2.0 bar.
5
Purge as much air as possible from the water circuit.
6
Close the drain and fill valve.
7
Disconnect the water supply hose from the drain and fill valve.
4.4.3
To fill the domestic hot water tank
For installation instructions, see the installation manual of the
domestic hot water tank.
4.4.4
To insulate the water piping
The piping in the complete water circuit MUST be insulated to
prevent condensation during cooling operation and reduction of the
heating and cooling capacity.
If the temperature is higher than 30°C and the humidity is higher
than RH 80%, the thickness of the sealing materials should be at
least 20 mm to prevent condensation on the surface of the sealing.

harmonic currents produced by equipment connected to
public low­voltage systems with input current >16 A and
≤75 A per phase.).
This equipment complies with EN/IEC 61000­3­11
(European/International Technical Standard setting the
limits for voltage changes, voltage fluctuations and flicker in
public low­voltage supply systems for equipment with rated
current ≤75 A) provided that the system impedance Zsys is
less than or equal to Zmax at the interface point between the
user's supply and the public system. It is the responsibility
of the installer or user of the equipment to ensure, by
consultation with the distribution network operator if
necessary, that the equipment is connected only to a
supply with a system impedance Zsys less than or equal to
Zmax.

During connection of the backup heater, miswiring is possible. To
detect possible miswiring, it is highly recommended to measure the
resistance value of the heater elements. Depending on the different
backup heater types, following resistance values (see table below)
should be measured. ALWAYS measure the resistance on the
contactor clamps K1M, K2M, and K5M.

If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if the leaving
water temperature control on the unit's user interface is
turned ON.
▪ 1 (Normally closed): The alarm
output will NOT be powered when an
alarm occurs. This installer setting
allows distinction between detection
of an alarm and detection of a power
failure to the unit.

Description
There is a risk of space heating (cooling) capacity
shortage/comfort problem (in case of frequent domestic hot
water operation, frequent and long space heating/cooling
interruption will happen) when selecting [6­0D]=0 ([A.4.1]
Domestic hot water Type=Reheat only) in case of a
domestic hot water tank without an internal booster heater.
Leaving water temperature modulation:
▪ 0 (No): Disabled
▪ 1 (Yes): Enabled. The leaving water
temperature is calculated according
to the difference between desired
and actual room temperature.
This allows better matching of the
heat pump capacity to actual
required capacity and results in less
start/stop cycles of the heat pump
and more economic operation.

▪ 2­way valve test
Hand­over to the user
Once the test run is finished and the unit operates properly, please
make sure the following is clear for the user:
▪ 3­way valve test
▪ Bottom plate heater test
▪ Fill in the installer setting table (in the operation manual) with the
actual settings.
▪ Bivalent signal test
▪ Alarm output test
▪ Make sure that the user has the printed documentation and ask
him/her to keep it for future reference. Inform the user that he can
find the complete documentation on the url as earlier described in
this manual.
▪ Cooling/heating signal test
▪ Quick heat­up test
▪ Circulation pump test

▪ Explain the user how to properly operate the system and what he/
she has to do in case of problems.
Checklist before leaving the
installation site
The minimum flow rate during backup heater/defrost
operation is guaranteed in all conditions. See "To check
the water volume and flow rate" in "3.1 Preparing water
piping" on page 4.
▪ Show the user what he/she has to do in relation to maintaining the
unit.
▪ Explain the user about energy saving tips as described in the
operation manual.
Recommended procedure
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 "6.4 To perform an
actuator test run" on page 18).
4
Go to [6.1.8]: > Information > Sensor information > Flow rate
to check the flow rate. During pump test run operation, the unit
can operate below this minimum required flow rate during
defrost/backup heater operation.
Bypass valve foreseen?
Yes
No
Modify the bypass valve setting
to reach the minimum required
flow rate + 2 l/min
In case the actual flow rate is
below the minimum flow rate
(required during defrost/backup
heater operation), modifications
at hydraulic configuration are
required. Increase the space
heating loops that can NOT be
closed or install a pressure
controlled bypass valve.
6.6
To perform an underfloor heating
screed dryout
Prerequisite: Make sure there is ONLY 1 user interface connected
to your system to perform an underfloor heating screed dryout.
Prerequisite: Make sure the user interface shows the home screens
