4.4.1 Display settings
[→ Main menu → Settings → Display]
This menu can be used to set the following parameters: Language,
date, time, LCD brightness and LCD illumination time.
Further explanations and possible settings for this menu can be
found in
Chap. 7.5 .
INFORMATION
Increasing the brightness of the LCD display beyond the
factory-set value will reduce the life of the display.
4.4.2 System
[→ Main menu → Settings → System]
This menu combines basic parameters of the heating system.
Further explanations and possible settings for this menu can be
found in
Chap. 7.5.2 .
4.4.3 Additional heat generators
[→ Main menu → Settings → Ext. source]
This menu can be used to configure the integration of an optional ex-
ternal heat source.
The heat supplied by an alternative WEZ must be fed to the unpres-
surised storage tank water in the Daikin Altherma ETS(X/H) hot wa-
ter storage tank.
▪ On use of the optional EKBUxx backup heater, this is carried out
due to the design installation situation.
▪ If an alternative WEZ (e.g. gas- or oil-fired boiler) is used, this can
be hydraulically integrated
▪ unpressurised via the connections (solar feed and solar return)
of the hot water storage tank or
▪ in the case of Daikin Altherma ETS(X/H) ...B device types, via
the integrated pressurised solar system heat exchanger
The setting of the [Config. ext. heat source] parameter is used to
define if any additional heat generator (WEZ) is available for do-
mestic hot water preparation and heating support, and which.
▪ No external heat source
▪ Optional backup heater
▪ Ext. heat sources HW and HZU: Alternative WEZ provide do-
mestic hot water preparation and backup heating. To request the
WEZ, relay K3 on PCB RTX-EHS is switched.
▪ Ext. heat source HW or HZU: Alternative WEZ 1 (optional backup
heater EKBUxx) undertakes domestic hot water preparation and
alternative WEZ 2 undertakes heating support. To request WEZ 1,
relay K3, and to request WEZ 2, relay K1, on PCB RTX-EHS are
switched respectively. Heed warning notice! The operation of an
additional alternative WEZ is also influenced by the settings of the
[Bivalence function] and [Bivalence temperature] parameters.
Further explanations and possible settings for this menu can be
found in
Chap. 7.5.3 .
4.4.4 Inputs/Outputs
[→ Main menu → Settings → Inputs/Outputs]
This menu can be used to adjust parameter for inputs and outputs of
the controller PCB to optimise the system controller individually.
Smart grid
WARNING
There is a danger of scalds at hot water target temperat-
ures over 65 °C. This is possible because the utility com-
pany (EVU) is entitled to control current draw optimised ac-
cording to supply and demand in the definitions for Smart
Grid.
Due to such forced charging, the hot water target temper-
ature in the hot water storage tank can exceed 65 °C.
This storage tank charging is carried out even when the
[Standby] operating mode is set.
▪ Install scald protection in the hot water distribution line.
To use this function, a special electricity meter with SG receiver to
which the Daikin Altherma ETS(X/H) must be connected is required.
As soon as the function is activated by the [Smart grid] parameter,
the heat pump is set to an operating mode as per
Tab. 4-4 depend-
ing on the utility company signal.

AUX switching function
Setting the [AUX switching function] parameter selects the switching
conditions for the potential-free AUX switching contact (toggle switch
output A). This switching contact can be used to control an external
heat generator, for example.
If one of the switching conditions is fulfilled, the potential-free switch-
ing contact is switched after the time set in the [AUX wait time] para-
meter.
AUX switching contact (toggle switch output A ) is not switched if
setting is deactivated.
