IMPORTANT! READ THIS FIRST BEFORE COMMENCING INSTALLATION
MULTI-MAGIC AMBIENT SENSOR INSTALLATION
This sensor measures the external air temperature and relative humidity.
It is intended for use with a compatible CW-80 or CW-H cooler.
One sensor can be connected per cooler.
Recommended Cable Specification
The sensor requires 24VDC power and 2 signal wires.
- Instrumentation Cable
- 4x 0.5mm2 (AWG 20) conductors;
- 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.
Note! 24VDC power can be supplied by the cooler (as shown) or a separate power supply (not included).

CONNECTING
After installation, use the LEFT/RIGHT buttons to navigate to the SENSORS
screen on the cooler PLC screen.
Select the ENABLED/DISABLED field under the AMBIENT sensor and set to ENABLED.
Check the Temperature and R/H values on cooler PLC screen are present and
correct.
Units can be changed between oC and oF in the PLC settings.

AMBIENT CONDITIONING MONITORING
Ambient Conditioning Monitoring is a special operating mode exclusive to the
Multi-Magic Wall Controller. It uses advanced logic to predict the cooler
supply air temperature based upon measured external ambient temperature and
relative humidity
conditions.
When the Wall Controller detects that the predicted supply air temperature is
higher than the current internal room temperature it stops the connected
coolers, even if the room temperature is higher than the set point.
For systems with more than one cooler, one ambient sensor can be connected per
cooler, allowing multiple sensors inputs to be averaged together.
EXAMPLE SETUP
EXAMPLE
FUNCTION
Room Temperature (RT) = 18.0 °C
Wall Controller Set Point (SP) = 17.0 °C
Cooling is requested as RT > SP
Installed Cooler(s) = CW-H15
Ambient Conditions as measured by Sensor = 38 C and 20% RH Predicted Supply
Temperature (PST) = 19.5 oC
Coolers are disabled as PST > RT This mode is particularly suitable for
applications which require room temperatures less than 20 oC
Coolers will automatically resume running when either;
- Ambient Conditions change, allowing predicted supply temperature to be lower than room temperature.
- Room Temperature rises above predicted supply temperature.
If the coolers have been stopped due to Ambient Conditioning Monitoring, a warning triangle and the predicted supply temperature appears on the Wall Controller main **page. NOTE! Ambient
Conditioning Monitoring is not compatible with the Multi-Magic Wall Controller
Minimum/Maximum Fan Speed limit function. See Wall Controller manual for more
information.
