Relay Test - Daikin EHSX04P30D Manuel D'utilisation

Relay Test

[→ Main menu → Configuration → Addition → Relay test]
This program allows testing of internal switching relays. This may be
necessary in the event of malfunctions, error messages or as part of
annual maintenance. When the menu is opened, all relays are deac-
tivated. Selecting one or more relays activates them. When the
menu is exited, all relay tests are terminated.
The relay test menu is operated in the same way as list entries (see
Chap. 3.3.3). However, several relays can be activated in parallel in
the relay list for testing. To do this, select the corresponding relay
with "OK". Activated relays are indicated by a tick.
Floor screed dryout
[→ Main menu → Configuration → Addition → Screed]
The screed drying is started in the menu according to the settings in
[Screed Program]. The program is used exclusively for the pre-
scribed drying of newly created screed for floor heating systems.
The first day of the screed program begins after activation of the pro-
gram at the change of day at 00:00.
Screed drying is a special function and is not interrupted by any
other operating mode. It can only be activated by the heating expert
for the direct HC and/or optionally connected mixed HCs. It must be
activated separately for each HC.
INFORMATION
Before starting the screed drying, the [Room thermostat]
and [Interlink function] parameters must be deactivated.
During a short-term power failure, a previously activated
screed drying is continued at the point of the interruption.
After activation of the screed drying, all weather-compensated con-
trol functions of the respective HC are switched off. The respective
HC works as a constant temperature control regardless of the oper-
ating mode and switching times.
Already activated screed drying can be deactivated at any time. After
ending the screed drying, the parameter is automatically set to "Off"
and the HC works according to the currently set operating mode
again.
Floor screed program
[→ Main menu → Configuration → Addition → Program]
This menu allows the individual adjustment of the factory settings for
the duration and feed target temperatures of the screed drying.
Changes can only be made after entering the specialist code.
Changing the screed program
A separate feed target temperature can be set for each day for a
maximum duration of 28 days. The end of the screed program is
defined by the first day without a preset feed target temperature.

Example: Increase the feed temperature of the 3rd day to 40 °C and
stop the program on the 8th day [→ Main menu → Configuration
→ Addition → Program]:
1 Turn the rotary button clockwise until the day selection is set to
3.
2 Briefly press the rotary button to confirm ("OK").
è The temperature field is displayed in blue.
3 Turn the rotary button clockwise until the temperature selection
is 40 °C.
4 Briefly press the rotary button to confirm ("OK").
è Temperature selection of the next day is shown in blue
5 Briefly press the rotary button several times until the day selec-
tion is set to 8.
6 Turn the rotary button anticlockwise until the temperature selec-
tion is set to "Off".
7 Briefly press the rotary button to confirm ("OK").
è Day 8 to day 28 are set to "Off", Confirm icon is shown in
blue
8 Briefly press the rotary button to confirm ("OK").
è The programming is saved and the menu is exited.
Typical screed programs
Function heating
The function heating serves as proof of the production of defect free
work for the heating engineer. A prefabricated heating protocol relat-
ing to floor heating systems can be found on the manufacturer's In-
ternet portal.
In this sense, the function heating (identical with "Heating" in
EN 1264, section 5.2) is not considered as a heating process to
achieve workability of the screed. Generally, a special screed curing
heating and/or mechanical drying is required for this.
The heating of cement screeds should be carried out after 21 days
at the earliest and of anhydrite screeds after 7 days at the earliest in
accordance with the specifications of the manufacturer. The first
heating begins with a feed temperature of 25 °C that must be main-
tained for 3 days. Afterwards, the heating is carried out with the max-
imum set feed temperature for the HC (limited to max. 55 °C), which
must be maintained for a further 4 days.
Due to the insulating effect of the DUO heating pipe for System 70,
the screed function must be carried out at higher temperatures. The
temperature profile must be adapted in the [Screed Program] para-
meter for this use case. For System 70, the heating begins at a tem-
perature of 38 °C that is maintained for 3 days. The set maximum
HC temperature (limited to 70 °C) is then maintained for 4 days.
