8.46 EST3 Installation and Service Manual
Signature series devices require a solid connection at their
terminals. If a wire can be wiggled, it will be subject to contact
resistance variations due to temperature changes, resulting in an
intermittent connection, which will affect communication
between the Signature devices and the control module. Use the
proper size screwdriver and tighten all connections securely.
