2.2 General notes
nA mains power line must be routed to the
indoor module.
nThe indoor module HTS 90 needs to have a
one-phase power supply from 230 V / 1~/50 Hz
and the indoor modules HTS 130/200/260
need to have a three-phase power supply from
400 V / 3~/50 Hz.
nThe electrical connection between outdoor-
and indoor modules by means of several con-
trol lines.
nA connection schematic along with corre-
sponding circuit diagrams can be found in the
'Connection diagram' chapter of this manual.
nIf an auxiliary electric booster heating is
needed in the indoor module one three-phase
power supply 400 V / 3~/50 Hz shall be pro-
vided.
nPower to the indoor module may not be discon-
nected by the power company when fitted with
an off-period circuit (anti-freeze protection).
nThe Smart-Control needs to know whether a
power-company release- or off-period is in
effect (contact S16). An electrically-isolated
switch must be installed for this purpose. (con-
tact closed signifies release, while contact
open signifies an off-period).
nSpecial rates for heat pumps may be offered
by the power-company (utility).
nAsk your local power company about the
details of any rates that might be available.
DANGER!
All electrical installation work must be done by
an electrician.
WARNING!
Always note the currently applicable VDE
guidelines and the notes in TAB 2007. The size
and type of the fuse are to be taken from the
technical data.
WARNING!
All cable sizes are to be selected according to
VDE 0100. Special attention should be given to
cable lengths, cable type and the kind of instal-
lation. The information in the connection dia-
gram and in the system overview are to be
seen as an acceptable installation possibility
only in a standard case!
NOTICE!
The electrical connection for the units must be
made at a separate feedpoint with a residual
current device in accordance with local regula-
tions and should be laid out by an electrician.
Check all plugged and clamped terminals to
verify that they are seated correctly and make
permanent contact. Tighten as required.

connection of the inner module.
1. Remove the cover from the indoor module by
pressing it upwards and pulling it forwards
out of the rear groove.
2. Guide the supply cable to the indoor module
through the cable openings, and also route
the control cable between indoor and outdoor
modules and the cables for external devices
and sensors into the indoor module. Note
that the cable openings are located at the
top.
3. Connect the mains power supply line and the
control line of the indoor module to the termi-
nals.
4. Connect all secondary consumers
(HGM,HGU, changeover valves etc.) to the
I/O module.
NOTICE!
Attach cables in accordance with the connec-
tion schematic and/or the circuit diagram in the
control box.
NOTICE!
Ensure correct polarity when connecting the
electrical leads, especially the control cable.
The number of lines and the sensors is
dependent on the configuration of the heating
system and the components.
At the site, avoid adding cable inlets.
NOTICE!
It is necessary to provide a separate RCD 100
mA, type B (universal current-sensitive) with a
contact load of 40 A for the heat pump.
2.4 Electrical connection - outdoor

nFollow the connection schematic and the circuit
diagrams ( Ä Chapter 2.6 ‘Terminal block / key’
on page 14).
nWhen connecting the control cable, make sure
that polarity is correct.
nIf the outdoor module is installed on a roof, it
and the supporting structure must be earthed
separately (connection to lightning conductors
or foundation earth/ground feature).
Temperature sensors
nThe number of sensors required can vary with
the type of system.
nObserve the pertinent notes for the sensor
position found in the hydraulic schematic.
nThe standard scope of delivery includes the
outdoor sensors (S10), an immersion sensor
(provided for use as a domestic hot water
sensor - (S08).
nWhen connecting up a solar system, use a
PT-1000 sensor (S01) as a collector sensor
and a PT-1000 sensor (S02) as the lower
storage tank sensor.
nAll sensors are to be connected to the indoor
module switch cabinet in accordance with the
terminal assignment diagram.
Contact sensor
Contact sensors can be mounted on the pipes, to
measure the heating-circuit temperatures, for
example.
nThe contact sensors are fastened to a pipe
with the accessories provided.
nClean the appropriate point. Subsequently a
thermal compound (A) is applied and the
sensor is fixed in position.
Fig. 4: Securing the inductive sensor (figure sim-
ilar)
If the sensor cables are too short, they can be
extended up to a maximum of 100m with wire
having a cross-section of 1.5 mm².
11

Outdoor sensor
The connection of an outdoor sensor is always
required for Smart Control.
nMount the outdoor sensor pointing skyward, in
a north-easterly direction, about 2.5 metres
above the ground. It may not be subjected to
direct sunlight and is to be protected against
excessive wind. Installation above windows or
air ducts is to be avoided.
nIn order to carry out the installation, remove the
cover and secure the sensor with the screw
