important to:
• clean the outside of the front plate and the inside of
the back plate with a dry cloth
• verify the tension of all wires and cables each time
you service the controller
Disposal
The Waste Electrical and Electronic Equipment
(WEEE) Directive sets regulations for the recycling and
disposal of products. The WEEE 2002/96/EG Directive
applies to stand-alone products that can function on
their own and are not a part of another system or piece
of equipment. For this reason, Johnson Controls®
products are exempt from the WEEE Directive.
Nevertheless, they are marked with the WEEE symbol,
indicating the devices are not disposed with municipal
waste.
Dispose of products at the end of their useful life
according to local regulations and the WEEE Directive.
