Description of the RTH receiver (AURATON 3021 RTH)

The AURATON RTH receiver cooperates with the AURATON 3021R
wireless receiver. The receiver is installed on the heating or air
conditioning device and can operate under the load of 16 A.

The LED light’s green – the output device is off (the contacts

COM and NC are closed).

The LED light’s red – the output device is on (the contacts

COM and NO are closed).

The LED flashes green – the RTH receiver awaits the device
to be paired (chapter: “Pairing the wireless regulator and the

RTH receiver”).

The LED flashes red – the RTH receiver awaits the device
to be deregistered (chapter: “Deregistering the regulator

from the receiver”).

The LED flashes alternating red and green:

ALARM - the RTH receiver has lost connection with one of

the paired devices (chapter “Special situations”).

RESET - receiver deregisters all previously paired devices -

(chapter “Deregistering all devices paired with the
RTH receiver”).

Selecting proper location for temperature
controller

Controller location largely affects its proper operation. When located
in a place without air circulation or exposed to direct sunlight, the
controller may not control the temperature properly. The controller
should be located on an internal wall of a building (partition wall) in
a place with free air circulation. Avoid locations near sources of heat
(TV set, heater, refrigerator) or places exposed to direct sunlight.
Location near doors and the resultant vibration may cause the
controller to function improperly.

Battery installation / replacement

The battery socket is located inside the controller, at the front of the
enclosure. To install the batteries, remove the controller enclosure
as described in the "Wiring your AURATON 3021" section.

NOTE: We recommend using alkaline bateries to supply AURATON
controllers. Rechargeable batteries should not be used because
their rated voltage is too low.

To fix the AURATON 3021 controller to the wall:

1. Remove the enclosure (as described in the "Wiring your

AURATON 3021" section).

2. Drill 2 holes diameter 6 mm

in the wall (use the back of

the controller enclosure to set
the right spacing of the
holes).

5. Replace the controller enclosure.

NOTE: No expansion bolts are needed for wooden walls. Just drill holes

diameter 2.7 mm (instead of 6 mm) and screw the screws directly into
the wood.

Fastening the RTH receiver

cover

NOTE !

When installing the receiver its power
supply must be disconnected. It is
recommended that the installation is
performed by a qualified specialist.

The permanent electrical system of
a building must include a breaker and
an overcurrent protection.

!

1. Take off protective covers from the lower
and upper part of the receiver.

2. Take off cable tie clamps from the lower and

upper part of the receiver.

3. Connect the heating device to the control

connection terminals of the receiver.

Proceed in accordance with the service
manual of the heating device. Most
commonly, the COM (common) and NO
(normally open) terminals.

4. Connect power supply conductors to the

power supply terminals of the receiver,
observing safety rules.
