4Holes for temperature and humidity measurement
The Multi-Magic Wall Controller should be placed indoors, approximately 1.5 metres (5’) above the
oor, in the same zone in which cooling is required. Placement is critical for correct functioning of
the temperature and humidity sensors inside the Controller.
The following points must be taken into consideration:
• Avoid direct sunlight exposure.
• Avoid mounting on external walls.
• Avoid mounting the wall controller near heat sources such as stoves and televisions.
• Do not locate in the direct airow of the duct outlets.
• Do not locate in strong drafts or in dead spots such as cupboards/drawers.
• Always seal the wall cable entry hole.
• Avoid blocking or restricting the vent holes located on the underside of the Wall Controller, as
this is where the sensors are located. Important! Drafts within the wall cavity can impact the
temperature and humidity reading of the wall control. We recommend that the cable access
hole be sealed, but in such a way that the cable can still retreat into the wall cavity.
• The Wall Controller shall be mounted vertically.

COMMUNICATION CABLE SPECIFICATION
• Suitable for Modbus RS 485 applications
• Minimum 1 twisted pair (TP) and a third conductor
• Copper Conductors
• 0.5 mm2/ AWG 20
• Braided Shield with Drain Wire
• Characteristic impedance 120Ω
• Nominal capacity between conductors 89 pF/m
• Nominal capacity between conductors and shielding 161 pF/m
Use the twisted pair for the ‘+’ and ‘-‘ signal terminals. Use the 3rd conductor for the signal GND
terminals. Attach the braided shield / drain wire to the EARTH terminal at one end only.

WIRING REQUIREMENTS
• Communication wiring must be kept separate from AC power wiring.
• Always route communication cables at least 300mm (12”) away from high voltage cables and
high-power machines.
• Crossover high power cables at right angles.
• Maximum cable length to the rst cooler is 100m.
• Maximum cable length between each cooler is 100m.
Note: Non-shielded cables are not protected against electromagnet interference which can cause
signal degradation.
Attach the 120Ω resistor (supplied with Wall Controller) between the "+" and "-" terminals of
the Wall Controller
Attach the 120Ω resistor (supplied with Multi-Magic coolers) between the "+" and "-"
terminals of the last cooler on the RS 485 Modbus network.
Do not t the 120Ω resistor to coolers installed between the Wall Controller and the last cooler..
See Appendix for example wiring schematics

POWER
Characteristic Specication
Power supply 24 V AC/DC +/-10 %
Power consumption 3.2 VA 1.3 W max
Fuse Recommendation (not included) Type T 500mA
The Multi-Magic Wall Controller can be powered by either a cooler on the network or a dedicated
power supply.
Note: Should a networked cooler be used for providing power, turning power o the cooler will
prevent the Wall Controller from controlling the remaining coolers on the network.
Use proper wire sizes to meet voltage and current requirements and use copper conductors.
If using a dedicated power supply, it must be rated Safety Extra Low Voltage (SELV) according to
IEC 61140. These sources of power are isolated between the electrical input and output circuits of
the power supply as well as simple separation from ground (earth), PELV, and other SELV systems.
