Please read this manual completely before commissioning!
2. Assembly of the controller HR3
2.1 Wall mounting
Simple wall mounting of the base with a 2-point fixture by means
of fastening screws (4x6) and plugs (M6).
2.2 Electrical connection
The installation is to be performed according to VDE or to the
applicable local regulations by qualified specialist staff!
The connecting base is divided in extra-low voltage and line
voltage by a separation panel. The live supply lines are introduced
into the right base side and are fixed with the joined strain reliefs.
The probe and extra-low voltage lines are to be inserted into the
left side of the connection base.
The protective conductors of the supply main and the plugged
consumer are to be connected to the 3-pole earthing terminal
strip!
Then, the wires are to be laid on according to the plan of termi-
nal connections in the following order:
Left base side: Probe connection clamps (5V DC)
Kl. 1/4 temperature probe „S1“ -outside probe
Kl. 2/4 temperature probe „S2“ -flow probe
Kl. 3/4 temperature probe „S3“ -RT21/remote control (optional)
Kl. 5 remains unused
Right base side: mains supply clamps (230V AC 50Hz)
Kl. 7 relay output „R1“ for the heating pump
Kl. 8 relay output „R2“ for the heating mixer „Open“
Kl. 9 zero conductor N for heating pump and heating mixer
Kl.10 zero conductor N of the supply main and circulation pump
Kl.11 external conductor L of the supply main
Kl.12 relay output „R3“ for the heating mixer „closed“
The connection of all protective conductors PE is performed on
the 3-pole earthing terminal strip.
2.3 Cable installation
The temperature probe wires are to be laid separate from the
supply lines in order to prevent from interference impulses (e.g.
by induction). For the extra-low voltage wires the safety
regulations of the VDE 0100 part 410 for the protection of extra-
low voltage are to be followed. If required, the cables of the
temperature probes may be extended up to about 50 m e.g. by a
3 x 1.5 NYM cable without influencing the measuring accuracy.
In this case, please make absolutely sure that the clampling of
the extension has no transition resistancies.

3. Temperature probe with KTY81-210 sensors
A correct assembly and the right placing of the probe is decisive
for the total functioning of the installation. Make sure that the
temperature probe is really mounted to the area which is to be
measured and that the probe cable may be laid in a tube isolation
on a length of about 20 cm from the measuring point and that it
is in this way protected against cooling down.
4. Commissioning
Safety note: When working with the controller and the plugged
consumers, the mains tension is to be disconnected for all poles
as due to the electronic switching of the devices, residual current
might flow.
Caution: The controller does not replace safety technical
equipment in any case. Measures, such as antifreeze, protection
against scald, protection against overpressure, etc. are to be
performed for the installation if required. Plugging of the main
module to the wall base (idle!).
After switching on the the supply voltage, the controller is ready
for operation.
Course of the parametrizing for the specialist:
1. Change language if required (refer to 8.6)
2. Set clock (refer to 8.1)
3. Set operating times (refer to 8.3)
4. Perform setting of desired values (refer to 8.4)
5. Check mixer running time and set if requried (refer to 8.6)
6. Function test for manual operation (refer to 8.5)
7. Checking the temperature indication (refer to 8.2)
8. Save user settings (refer to 8.8)
9. If required interlocking of the manual settings (refer to 8.7)
Error messages caused by e.g. defective probes are shown by
flashing of the red LED. The error is also shown in the menu
service value as clear text.
In case of an error, the service values are to be logged in order
to allow the specialist staff a remote diagonstic by phone.
5. Notes for malfunctions
Before opening the device, switch off the line voltage!
The controller is protected by a fine-wire fuse 2AT. It may be
checked and replaced if necessary after switching off the current
and removing the pluggable module from the wall base as well
as after removing the back panel. The function of the temperature
probe may be controlled with an ohmmeter according to the table.
If a probe which is required is interrupted, the controller will switch
off the corresponding function.
