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 36 hours after the first power-on.
If the screed dryout still needs to be performed after the
first 36 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
▪ [C‑02]=0
▪ [D‑01]=0
▪ [4‑08]=0
▪ [4‑01]≠1
Resume after power failure
If power is restored after a power failure, underfloor heating screed
dryout automatically resumes its operation.
9 Hand-over to the user
Once the test run is finished and the unit operates properly, make
sure the following is clear for the user:
▪ Fill in the installer setting table (in the operation manual) with the
actual settings.
▪ 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 at the URL mentioned earlier in
this manual.
▪ Explain the user how to properly operate the system and what to
do in case of problems.
▪ Show the user what to do for the maintenance of the unit.
▪ Explain the user about energy saving tips as described in the
operation manual.
10 Maintenance and service
NOTICE
Maintenance MUST be done by an authorised installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000

▪ Pressure reducing valve of the domestic hot water tank kit
▪ Chemical disinfection
▪ Descaling
▪ Drain hose
▪ Fluid pressure of space heating and central water loop circuit
▪ Pressure relief valves (1 at central water loop side, 1 at space
heating side)

10.2.2 Yearly maintenance: instructions
Central water loop leakage
Open the front panels and carefully check if a leakage in the piping
from and to the central water loop is noticeable. See
"4.2.1 To open
the indoor unit" [ 4 6].
Temperature and pressure relief valve
Check for correct operation of the temperature and pressure relief
valve. Manually operate the temperature and pressure relief valve to
ensure free water flow through discharge pipe. Turn knob left.
Pressure reducing valve
Depending on local water conditions, annual inspection of the
integral line strainer, pressure reducing valve cartridge and seating
may be necessary.
