Connection variant 3
When connecting a Backup-Heater with a heating ele-
ment the parameter [EKBU1C / EKBU3C), Function
Heating ]=2 must be set.
Fig. 4-35 Connection Backup-Heater with a heating element (EKBU1C
/ EKBU3C) (for legend see fig. 4-33)
Warning!
When contacting a damaged connec-
tion cable of the Backup-Heater this can
cause electrocution and thus cause life-
threatening injury and burns.
● Do not repair the connection cable of
the Backup-Heater.
Always replace the complete
Backup-Heater.
4.5.13 Connection of an external heat generator
For heating support or as an alternative to an electrical Backup-
Heater (see section 4.5.12) you can connect an external heat
generator (e.g. gas or oil boiler) to the Daikin Altherma EHS(X/H).
The heat supplied by the external heat generator must be added
to the unpressurised storage tank water in the Daikin Altherma
EHS(X/H) hot water storage tank.
● Carry out hydraulic connection in accordance with one of the
two following possibilities:
a)
unpressurised via connections (solar infeed and
solar return) of the hot water tank
or
b)
on unit types Daikin Altherma EHS(X/H) B, via the
integrated pressurised solar heat exchanger.
– Observe the instructions concerning hydraulic connections
(see chapter 2.4)
– Examples of hydraulic connection (see chapter 9).
Demand from an external heat generator is switched to the RTX-
EHS circuit board via a relay (see fig. 4-36). The electrical con-
nection to the Daikin Altherma EHS(X/H) is possible as follows;
a)
External heat generator has a potential-free switch
contact connection for heat demand:
– Connection to K3, if the external heat generator takes
over the hot water generation and heating support
(setting parameter [Function Heating ]=2)
or
– Connection to K1 and K3 if two external heat generators
are being used (setting parameter [Function Heating ]=3).
Here K1 switches the external heat generator (e.g. gas or
oil boiler) for heating support and K3 the external heat
generator (EKBUxx) for hot water generation.
or
– Connection on AUX connection A (see section 4.5.17)
b)
External heat generator can only be switched via the
mains power supply:
Connection (~230 V, maximum load 3000 W) at K1 and
K3.
Caution!
Risk of voltage arcing.
● The connections on the RTX-EHS
circuit board must not be used for
switching the mains voltage (~230 V)
and protective low voltage
(SELV = "Safety Extra Low Voltage")
at the same time.
● Suitable electrical connection from the relevant installation
instructions for the external heat generation.
● Connect external heat generation to the Daikin Altherma
EHS(X/H) (fig. 4-36).
Connection X1 is a screw terminal.
Isolated 6.3 x 0.8 mm push-on receptacles are required for
connections X2_1/2/3.
