DC 5V or 12V is used at the contact points for the timer and switch so there is a load
of only approximately 1mA. Improper switch selection could cause improper operation.
Transit relay : This is used when installing the wiring in accordance with "6. Wiring Restrictions."
Electric wire : The length of the electrical wiring for the remote ON/OFF adaptor is 2 meters.
To extend this length, use sheathed vinyl cord or cable.
