Screed Program - Daikin EHS157034 Operating Instructions Manual

3 x Operation
4. Execute the programme by briefly pressing on the rotary
switch.

The respective values are reset to the factory setting.
5. Select "Return" with the rotary switch.
6. Confirm the changes with a brief push of the rotary switch.
Possibility 3
If fundamental changes to the Daikin Altherma EHS(X/H)
equipment for the function within the RoCon system are nec-
essary, the Basic Configuration can be reset using Technician
access rights to the factory settings or can be redefined.
1. Enter the expert code (see section 3.6.1).

The "Setup" level is displayed after entering.
2. Select the "System Config" level with the rotary switch.
3. Confirm the changes with a brief push of the rotary switch.

An overview is displayed.
4. Select the programme "Delete" with the rotary switch.
5. Confirm the changes with a brief push of the rotary switch.

Restart of the Daikin Altherma EHS(X/H) is performed.

The message "No Basic " is displayed.
6. Place the rotary switch in the "Info"

The message "Basic Configuration " is displayed.
7. There is now the facility either to select manual mode for the
equipment individually (a) or to load the factory settings
automatically (b).
a) Press the rotary switch briefly.

A parameter overview is displayed at the level "Basic
Configuration" and the settings can performed manually
as desired according to tab. 6-14.
b) Turn the Daikin Altherma EHS(X/H) off and restart it.

After the has restarted the question will be Daikin
Altherma EHS(X/H)posed whether the standard configu-
ration should be used. If it is confirmed with "Yes", the
preset basic configuration is loaded. If the answer
given is "No" the settings must be performed manually,
see a).
More detailed explanations and possible setting values for this function can be seen
in chapter 6.12.
After a reset to the factory settings via option 2 or 3, the
system must be configured again by the heating tech-
nician to the installation environment and all the cus-
tomer-specific parameters reset.

3.6.13 Screed Program

The Screed Program is intended exclusively for specified drying
of newly created screed in underfloor heating systems. This op-
erates the heat generator for several days according to a prede-
fined temperature profile (the predefined temperature profile is
based on the recommendations of the Bundesverbandes
Flächenheizungen (Federal Association of Surface Heating
Systems) for heating to cure the floor).
The temperatures and the duration of the Screed Program can be
adjusted as required, after entering the expert code, in the rotary
switch setting "Configuration"
ration" in the parameter [Screed Program].
The Screed Program is a special function and is not interrupted
by any other operating mode. It can be activated only by the
heating expert for the direct heating circuit and/or the op-
tionally connected mixed heating circuits. Each heating circuit
must be separately activated.

Prior to start of the Screed Program, the parameters
[Interlink fct] and [Room thermostat] must have been
deactivated.
In the event of a brief power failure the system contin-
ues with a previously activated screed function in place
of shutting down.
After activation of the Screed Program (parameter [Screed] = On)
all the weather-controlled regulating functions of the relevant
heating circuit are switched off. The relevant heating circuit op-
erates independently of the operating mode (switching times) as
a constant temperature regulator.
An already started Screed Program can be deactivated at any
time. At the end of Screed Programs the screed function the pa-
rameter is automatically set to "Off" and the heating circuit once
again operates according to the currently set operating mode.
Function heating
Function heating verifies that the installation is fault-free for the
heating engineer. A pre-prepared heating up protocol for Daikin
underfloor heating can be found in the Daikin Internet portal.
In this case, function heating (identical with "Heating up" in
EN 1264, section 5.2) does not constitute a heating up process
for drying and curing. Normally you need to carry out separate
heating process to cure the floor and/or perform mechanical
drying.
Heating up should be carried out no earlier than after 21 days for
cement screed, and no earlier than after 7 days for anhydrite
screed in accordance with the details provided by the manufac-
turer. The first heating up starts at a feed temperature of 25 °C,
which must be maintained for a period of 3 days. Then heating is
carried out at the maximum flow temperature set for the heating
circuit (limited to max. 55 °C) and this is then held for a further
4 days.
After the heating up process described, there is no guarantee that
the screedhas achieved the moisture content required to cure the
floor.
You must determine the moisture content in the screed by meas-
urement before laying the floor covering.
Procedure in accordance with EN 1264 Part 4:
The heating circuits must be checked for leaks by a
water pressure test once the anhydrite and cement
screeds are completed. The absence of leaks must be
ensured immediately before and during screed laying.
The level of the test pressure is at least 1.3 times the
maximum permissible operating pressure.
If there is a danger of freezing up, you must take suita-
ble measures, e.g. the use of antifreeze or temperature
control in the building. If antifreeze is no longer required
for intended use of the installation, you must remove
the antifreeze by draining it out and flushing the instal-
lation with at least 3 changes of water.
