Daikin Altherma low temperature monobloc

INFORMATION
▪ To purge air, use all air purge valves present in the
system. This includes the manual air purge valve of the
outdoor unit, as well as any field-supplied valves.
▪ If the system contains a backup heater, also use the air
purge valve of the backup heater.
▪ If the system contains valve kit EKMBHBP1, it is
required to – during the air purge – manually switch the
position of the valve kit's 3‑way valve by turning its
knob, this to prevent air from remaining in the bypass.
For more information, refer to the instruction sheet of
the valve kit.

Prerequisite:
Make sure there is ONLY 1 user interface connected
to your system to perform an underfloor heating screed dryout.

Make sure that the leaving water temperature home
page, room temperature home page, and domestic hot water home

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 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
