Daikin Altherma EHS(X/H)
Daikin Solar tank with integrated interior heat pump unit
008.1420744 – 06/2015
3 x Set-up and installation
● Connect the exterior temperature sensor to a twin-core
sensor line (minimum diameter 1
mm
2
).
● Install the sensor line to the Daikin Altherma EHS(X/H).
● Connect the sensor line to the plug connection J8 on the
board RoCon BM1 (see fig. 3-23).
Fig. 3-23 Connection of the exterior temperature sensor RoCon OT1 to
the Daikin Altherma EHS(X/H) (operating as a single solution
or master in a data bus)
After connecting the exterior temperature sensor RoCon OT1 to
the regulator RoCon HP of the Daikin Altherma EHS(X/H), the
parameter [Outside Config] must be set to "On".
3.4.12 Connection of an external switching contact
By connecting an external switching contact (fig. 3-24) the oper-
ating mode of the Daikin Altherma
EHS(X/H) can be changed.
The current operating mode can be switched thanks to a
cha
nging resistance reading (tab. 3-1). Changing the operating
mode is only effective as long as the external switching contact is
clo
sed.
The operating mode has an effect on the direct circuit of the
Daikin Altherma EHS(X/H), and on all other heating circuits that
can be optionally connected to this device.
The operating mode shown in the controller display can deviate
from the operating mode activated in the rotary switch setting
.
An operating mode activated by an external switch contact is
shown on the controller by "EXT.", followed by the symbol of the
operating mode (see operating instructions for the controller).
If special functions, such as "Manual Operation" are activated,
the
input is not evaluated.
Fig. 3-24 Connection of the EXT switching contact
Operating mode Resistance R
V
Tolerance
Standby < 680 Ω
± 5 %
Heating 1200 Ω
Reducing 1800 Ω
Summer 2700 Ω
Automatic 1 4700 Ω
Automatic 2 8200 Ω
Tab. 3-1 Resistance values for the evaluation of the EXT signal
When the resistance readings are greater than the
value for "Automatic 2", the input will be ignored.
NOTE REGARDING THE CONNECTION OF A
DAIKIN SOLAR SYSTEM
By means of the function [HZU] integrated into the
RoCon HP integrated [HZU] control unit
(see operating manual for the control unit) it is not nec-
essary to connect the EXT connection with the con-
nection of the burner blocking contact of the Daikin
s
olar system.
3.4.13 External demand signal (EDS)
By connecting the EDS switch contact to the Daikin Altherma
EHS(X/H) (fig. 3-25) and through the corresponding parameteri-
sation in its RoCon HP control unit, a heating demand can be
generated via an external switch contact. If the switch contact is
closed, the Daikin Altherma EHS(X/H) switches to the heating
mode. The flow temperature is adjusted to the temperature that
is set in the parameters [T-Flow Day].
The EDS switching contact has preference of a request via the
ro
om thermostat.
In Cooling, Stand-by, Manual and Summer mode, the switching
contact is not evaluated. In addition, the heating limits are not
taken into consideration.
