PHYSICAL DESCRIPTION & MOUNTING

WALL CONTROLLER DIMENSIONS AND SETUP NOTES

The Multi-Magic Wall Controller should be placed indoors, approximately 1.5 metres (5’) above the floor, 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 airflow 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.

PHYSICAL DESCRIPTION & MOUNTING

WALL CONTROLLER INSTALLATION INSTRUCTIONS

CONNECTING

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 first 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 fit the 120Ω resistor to coolers installed between the Wall Controller and the last cooler..
See Appendix for example wiring schematics

CONNECTING

POWER

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 off 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.
