3 x Set-up and installation
Demand from an external heat generator is switched to the RTX-
EHS circuit board via a relay (see
fig. 3-28). 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 Rod]=2)
or
Connection to K1 and K3 if two external heat generators
are bei
ng used (setting parameter [Function Heating
Rod]=3). Here K1 switches the external heat generator
(e.g. gas or oil boiler) for heating support and K3 the exter-
nal heat generator (EKBUxx) for hot water generation.
or
Connection on AUX connection A (see section 3.4.19)
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 =
"Sa
fety Extra Low Voltage") at the same time.
Suitable electrical connection from the relevant installation
instructions for the external heat generation.
