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.
Wiring your AURATON 3021
To connect the wiring, remove the enclosure as described below:
Wiring terminals are located in the controller back wall, under
the plastic cover.

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.
!
15
5. After connecting the conductors, they must be
secured with the cable tie clamps and reinstall
protective covers of the receiver.
To fasten the RTH receiver to the wall:
1) Remove protective covers from the lower and upper part of the regulator.
(See chapter: “Fastening the RTH receiver”).
2) On the wall, mark the location of holes for fastening screws.
3) In marked places, drill holes of a diameter corresponding to the bundled
wall plugs (5 mm).
4) Insert wall plugs into the drilled holes.
5) Screw in the RTH receiver to the wall with screws, making sure they hold
the receiver securely.
Fastening the RTH receiver to the wall
WARNING !
Cables supplied with the regulator are designed for conducting maximal
load of 2.5 A. If devices to be connected require more power, the cables need
to be replaced with cables of the appropriate cross-sectional area.
