Connecting the temperature sensor hot water
charging
The water sensor (BT6) and immersion heater sensor (BT19)
are located on HE 30/HEV 300/HEV 500 and are connected
using a cable between HBS 16 (terminal block AA22-X4)
and HE 30/HEV 300/HEV 500 (terminal block X101). Use
a 4 core cable of at least 0.5 mm2 cable area.

Connecting the current limiter
NOTE
Only applies to 3X400V.
When many power consumers are connected in the
property at the same time as the electric addition is oper-
ating, there is a risk of the property's main fuse tripping.
HBS 16 is equipped with an integrated current limiter that
controls the electrical steps and the compressor. If neces-
sary, the electrical steps are disengaged and/or the com-
pressor frequency is reduced.
A current sensor should be installed on each incoming
phase conductor in to the distribution box to measure the
current. The distribution box is an appropriate installation
point.
Connect the current sensors to a multi-core cable in an
enclosure next to the distribution box. Use unscreened
multi-core cable of at least 0.50 mm
2 , from the enclosure
to HBS 16.
In HBS 16 connect the cable to the current limiter board
(AA22) on terminal X1:8–11.
L1 connects on X1:8 and X1:11.
L2 connects on X1:9 and X1:11.
L3 connects on X1:10 and X1:11.
X1:11 is the common terminal block for the three current
sensors.

The size of the property's main fuse is set using the knob
(R24) on the circuit limiter board, (AA22). The setting can
be read in menu 8.3.1.
Connection of centralised load control/tariff
In those cases centralised load control or tariff control is
used this can be connected to the terminal block (X1) on
the EBV card (AA22), which is positioned behind the front
cover.
Tariff A, the electrical addition is disconnected. Connect a
potential free contact function to terminal X1:5 and X1:7.
Tariff B, the compressor in AMS 10 is disconnected. Con-
nect a potential free contact function to terminal X1:6 and
X1:7.
Tariff A and Tariff B can be combined.
A closed contact results in the electrical output being dis-
connected.
Connecting external contacts
RG 10, sensor for changing the room temperature
An external sensor (BT50) can be connected to HBS 16 to
change the flow temperature and with that set the room
temperature, for example, a room sensor (RG 10, access-
ory). Connect the sensor to the terminal block from X4:1
to X4:3 on the current limiter board (AA22) according to
wiring diagram.
Activated in menu 9.3.6.
The difference between the room temperature and the
set room temperature affects the flow temperature. The
required room temperature is set using the knob on RG
10 and is shown in menu 6.3.
Contact for changing the room temperature
Climate system 1:
An external contact function can be connected to HBS 16
to change the flow temperature and in doing so change
the room temperature, for example, a room thermostat
or a timer. The contact must be potential free and non-
locking and connected to terminal block X1:3 and X1:4
on the current limiter board (AA22).
When the contact is closed, the heating curve offset is
changed by the number of steps shown here. The value is
adjustable between -10 and +10. The value for the change
is set in menu 2.4, "External adjustment".
