Installation
NOTICE
INSTALLATION
•
The system must be installed correctly by a qualified technician.
•
If replacing an existing Room Controller, label wires before removal of Controller.
•
Electronic controls are static sensitive devices. Discharge yourself correctly before
manipulating and installing Room Controller.
•
A short circuit or wrong wiring may permanently damage Room Controller or equipment.
•
All Room Controllers are designed for use as operating controls only and are not safety
devices. These instruments have undergone rigorous tests and verification prior to shipping
to ensure proper and reliable operation in the field. Whenever a control failure could lead to
personal injury and/or loss of property, it becomes the responsibility of the
user/installer/electrical system designer to incorporate safety devices (such as relays, flow
switch, thermal protections, etc.) and/or an alarm system to protect the entire system
against such catastrophic failures. Tampering with the devices or unintended application of
the devices will result in a void of warranty.
•
This device must be installed to provide a separation distance of at least 8in (20cm) from all
persons and must not be located or operating in conjunction with any other antenna or
transmitter.
•
Refer to the Room Controller User Interface Guide for information on how to configure the
Room Controller.
Failure to follow these instructions can result in equipment damage.
