Function
After the described heating process, it is not yet assured that the
screed has reached the required moisture content for workability of
the screed.
The moisture content in the screed must be checked by measure-
ment prior to laying the surface covering.
INFORMATION
Procedure in accordance with EN 1264 Part 4:
For anhydrite and cement screeds, the HCs must be leak
tested by a water pressure test after completion. The leak-
tightness must be ensured immediately before and during
the laying of the screed. The height of the test pressure is
at least 1.3x the maximum permitted operating pressure.
Suitable measures must be taken if there is a risk of freez-
ing, e.g. use of antifreeze agents or heating the building. If
antifreeze agents are no longer necessary for the intended
operation of the system, the antifreeze agent must be re-
moved by draining and rinsing the system with at least 3
changes of the water.

Screed curing heating
The drying process for the screed cannot be exactly predicted. If
there is a high degree of humidity, sometimes it can stop completely.
The drying process can be speeded up by activating the floor heat-
ing (screed curing heating) or measures such as mechanical drying.
Each screed curing heating must be ordered separately by the client
as an extra service in accordance with German construction contract
procedures (VOB). The workability of the screed is a prerequisite for
the top floor installer to start work so that he can produce defect free
work.
With standard settings, the combined function and screed curing
heating program can be activated to achieve the required residual
moisture in the screed for workability of the screed (see
However, the residual moisture of the screed must basically be
checked metrologically before the flooring can be laid.

Parameter Reset
[→ Main menu → Configuration → Parameter reset]
All customer-specific parameter settings can be reset to factory set-
tings in this menu. This can be useful if the Daikin Altherma EHS(X/

Info
[→ Main menu → Information ]
This menu displays all system temperatures, the heat generator
type, various software information and the operating states of all sys-
tem components. The number of displayed parameters depends on
which components are connected. No adjustments can be made to
these values.

third page shows the compressor, pump and heating rod in white if
they are inactive and blue if they are active. The current valve posi-
tion is shown for both mixing valves.
