INFORMATION
When starting up the system in a cold climate, and NO
backup heater kit 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.

9.4.5
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 that the leaving water temperature home page, room
temperature home page, and domestic hot water home page 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.6.C]=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.
