3
Select a test and press
.
Example:
Heating.
4
Select OK and press
.
Result:
The test run starts. It stops automatically when done
(±30 min). To stop it manually, press
, select OK and press
.
INFORMATION
When starting up the system in a cold climate, and NO
backup heater kit (EKMBUHCA3V3 or EKMBUHCA9W1)
was installed, it may be required to start up with a small
water volume. To do this, gradually open the heat emitters.
As a result, the water temperature will gradually rise.
Monitor the inlet water temperature ([6.1.6] in the menu
structure) and make sure it does NOT drop below 15°C.
INFORMATION
If 2 user interfaces are present, you can start a test run
from both user interfaces.
▪ The user interface used to start the test run displays a
status screen.
▪ The other user interface displays a "busy" screen. You
cannot use the user interface as long as the "busy"
screen is shown.
If the installation of the unit has been done correctly, the unit will
start up during test operation in the selected operation mode. During
the test mode, the correct operation of the unit can be checked by
monitoring leaving water temperature (heating/cooling mode) and
tank temperature (domestic hot water mode).
To monitor the temperature, go to [A.6] and select the information
you want to check.
9.4.4
To perform an actuator test run
Purpose of the actuator test run is to confirm the operation of the
different actuators (e.g., when you select pump operation, a test run
of the pump will start).
Prerequisite:
Make sure the user interface shows the home screens
and that the space heating and domestic hot water demands are
turned off.
1
Set the user permission level to Installer. See
"To set the user
permission level to Installer" on page 49
.
2
Make sure the room temperature control, the leaving water
temperature control and the domestic hot water control are
turned OFF via the user interface.

Go to [A.7.4]:
> Installer settings > Commissioning >
Actuator test run.
4
Select an actuator and press
.
Example:
Pump.
5
Select OK and press
.
Result:
The actuator test run starts. It automatically stops when
finished. To stop it manually, press
, select OK and press
.
Possible actuator test runs
▪ Booster heater test
▪ Backup heater (step 1) test
▪ Backup heater (step 2) test
▪ Pump test
INFORMATION
Make sure that all air is purged before executing the test
run. Also avoid disturbances in the water circuit during the
test run.
▪ 2-way valve test
▪ 3-way valve test
▪ Bivalent signal test
▪ Alarm output test
▪ Cooling/heating signal test
▪ Quick heat-up test
▪ Circulation pump test
9.4.5
Underfloor heating screed dryout
This function is used for drying out the screed of an underfloor
heating system very slowly during the construction of a house. It
allows the installer to program and execute this program.
Make sure the user interface shows the home screens and that the
space heating and domestic hot water demands are turned off.
If a backup heater kit is part of the system, this function can be
executed without finishing the outdoor installation. In this case, the
backup heater will perform the screed dryout and supply the leaving
water without heat pump operation.
INFORMATION
▪ If Emergency is set to Manual ([A.5.1.2]=0), and the
unit is triggered to start emergency operation, the user
interface will ask confirmation before starting. The
underfloor heating screed dryout function is active even
if the user does NOT confirm emergency operation.
▪ During underfloor heating screed dryout, pump speed
limitation [9‑0D] is NOT applicable.
NOTICE
The installer is responsible for:
▪ contacting the screed manufacturer for the initial
heating instructions to avoid cracking the screed,
▪ programming the underfloor heating screed dryout
schedule according to the above instruction of the
screed manufacturer,
▪ checking the proper functioning of the setup on a
regular basis,
▪ selecting the correct program complying with the type
of the used screed of the floor.
NOTICE
To perform an underfloor heating screed dryout, room frost
protection needs to be disabled ([2‑06]=0). By default, it is
enabled ([2‑06]=1). However, due to the "installer-on-site"
mode (see "Checklist before commissioning"), room frost
protection will be automatically disabled for 12 hours after
the first power-on.
If the screed dryout still needs to be performed after the
first 12 hours of power-on, manually disable room frost
protection by setting [2‑06] to "0", and KEEP it disabled
until the screed dryout has finished. Ignoring this notice will
result in cracking of the screed.
The installer can program up to 20 steps. For each step he needs to
enter:
1
the duration in hours, up to 72 hours,
2
the desired leaving water temperature.
