POWER
Characteristic Specification
Power supply 24 Vdc +/-10 %
Power consumption 3.2 VA 1.3 W max
Fuse Recommendation (not included) Type T 500mA
The Climate Wizard Wall Controller can be powered via either a CW-H cooler on the network or a
dedicated power supply
Note: Should the CW-H cooler used for providing power be turned off the Wall Controller will be un -
able to control the remaining coolers on the network.
Use proper wire sizes to meet voltage and current requirements and 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.
