Air purging heat emitters or collectors
We recommend to purge air with the unit's air purge function (see
above). However, if you purge air from the heat emitters or
collectors, mind the following:
WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if an error
or is displayed on the home pages of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to
purge air is sufficiently ventilated. Reason: Refrigerant
might leak into the water circuit, and subsequently into
the room when you purge air from the heat emitters or
collectors.
7.2.2 To perform a test run
Prerequisite: Make sure that the leaving water temperature home
page, room temperature home page, and domestic hot water home
page are turned OFF.

INFORMATION
In case of third-party gas boiler:
When starting up the system in a cold climate, 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.
7.2.3 To perform an actuator test run
Perform an actuator test run to confirm the operation of the different
actuators. For example, when you select
Pump , a test run of the
pump will start.
Prerequisite: Make sure that the leaving water temperature home
page, room temperature home page, and domestic hot water home
page are turned OFF.
1 Set the user permission level to Installer. See "To set the user
permission level to Installer" [ 4 21].
2 Go to [A.7.4]: > Installer settings > Commissioning >
Actuator test run .
3 Select an actuator and press . Example: Pump .
4 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
▪ 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.
▪ 3-way valve test
▪ Bottom plate heater test
▪ Bivalent signal test (in case of third-party gas boiler)
▪ Circulation pump test
▪ Gas boiler test (in case of *HY32AA gas boiler)
INFORMATION
The setpoint during a boiler test run is 40°C. Keep in mind
the 5°C overshoot that is possible during boiler operation,
especially in combination with floor heating loops.
7.2.4 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 that the leaving water temperature home
page, room temperature home page, and domestic hot water home
page are turned OFF.
1 Go to [A.7.2]: > Installer settings > Commissioning >
UFH screed dryout .
2 Set a dryout program.
3 Select Start dryout and press .
4 Select OK and press .
Result: The underfloor heating screed dryout starts. It stops
automatically when done. To stop it manually, press , select OK
and press .
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 "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.
NOTICE
For the underfloor heating screed dryout to be able to start,
make sure the following settings are met:
▪ [4‑00]=1
▪ [D‑01]=0
▪ [4‑08]=0
▪ [4‑01]≠1
