4. Power supply and RS485 communication line
On wall controller AMR-OP70C/XX can be powered only by DC power supply.
Power supply must meet requirements listed in chapter 2. Technical
parameters.
The RS485 interface without galvanic isolation uses the common GND terminal
together with power supply. For proper working of RS485 is necessary to abide
the rules presented in Application Note AP0016 –Principles of using RS485
interface.

Each station on RS485 communication line must have properly set the line
termination. Configuration jumpers located near the connector are used for
connection termination. When jumpers are fitted, line termination is connected.
Line terminating stations must have the termination always connected,
intermediate stations –disconnected.

5. Mounting
On-wall controller is intended to be mounted in internal, dry environment.
Should be placed around 1.5 m above the floor, in an area with good and innate
air circulation. Controller should not be placed in area, where its temperature
can be affected by the wind, sunshine, heat radiation from the heater, or other
undesirable influences. If the inlet wires are led through the plastic pipe, it is
necessary to seal the pipe to avoid air flow.
Fig. 7 - On-wall controller mounting in vertical position (left), in horizontal
position (right)
On-wall controller is mounted according to Fig. 7 - left. Temperature sensor is
located in the bottom left corner.
On-wall controller is mounted according to Fig. 7 - right. Temperature sensor is
located in the bottom right corner.
Factory uploaded application requires vertical mount.
In case of incorrect mounting, temperature sensor is affected by the heat
radiated by the electronics of the controller, that results in incorrect temperature
readings.

5.1. Mounting procedure
1. Release the cover by pressing a latch on the on-wall controller's left side (for
example, with a screwdriver or a blunt-tip). Then take off on-wall controller
front part.
Fig. 8 - Place that must be pressed with blunt-tip
2. Mount rear cover on a selected location. There are two pairs of mounting
holes available.
3. Connect the communication and power supply wiring (according to chapter
4. Power supply and RS485 communication line).
4. Set the configuration jumpers (according to chapter 4. Power supply and
RS485 communication line).
5. Put the upper part on a rear cover and press gently until the latch clicks.
5.2. Installation rules
Use EMC filter on power supply input. This requirement can be revised based
on the environment nature, power source properties and wiring layout.
Cabling connected to the power supply and RS485 communication line
terminals must be shielded.
Connect negative power supply terminal (GND) and cable shielding to PE
terminal in one place, close to power supply.
It is necessary to perform connection of RS485 line according to
recommendations presented in Application Note AP0016 –Principles of using
RS485 interface.
All PE connections must be done with as lowest impedance as possible.
Technical parameters of on-wall controller are guaranteed only when these
wiring rules are applied.

6. Setup and operation of on-wall controller
On-wall controller has several working screens.
Basic is displayed all time.
User menu is displayed by touching on a particular area of
a display.
Configuration menu is displayed by touching continuously on a particular
area of a display.
Screen saver if allowed, it will be displayed after pre-set time of
controller inactivity.
6.1. Basic screen
The design of basic screen depends on application variant setting and on mode
of displaying measured values settings. Application variant is set by the service
organization, during on-wall controller instalation. Mode of displaying measured
values can be set in configuration menu. Part of the basic screen is same for all
variants, part depends on selected variant
