Automatically turn outdoor lights on after dark and off at daybreak, conserving energy when lights are not needed. A time delay prevents false switches due to light flashes.

Wall-mount controls require a base (sold separately).

For protection in washdown conditions with splashing water, corrosive liquid, and dust, these controllers have a wall-mount housing that meets NEMA 4X. They’re ideal for systems with rapid, unpredictable, or complex temperature changes. They turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control. All work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting it. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. These controllers include a highly sensitive Type J thermocouple probe to take temperature readings in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. Use the keypad to adjust the actuation point, reset point, and other settings.

The controllers have mechanical relay outputs that actuate circuits directly. All are 3PST (triple pole, single throw) and turn three circuits from off to on (normally open). They also have two additional outputs to actuate alarms or other simple devices.

Turn the dial to control humidity equipment.

Install sockets for medium (standard household) screw-in base light bulbs.

Styles A-C mount to outlet boxes.

If you don't have your remote, you can still open and close automatic overhead doors with a private 4-digit PIN. Use these transmitters to operate one transmitter or receiver. The keypad is backlit for visibility in the dark.

Hardwire these switches to automatic door openers, electromagnetic locks, and electric strikes to open doors with the touch of a button or wave of a hand. Mount them to electrical boxes or surface-mount boxes (sold separately). Instant-open switches provide immediate access. Time-delay switches allow time to reach the door before it opens.

Style 1-7 switches operate with the touch of a button. Style 7 switches are 36 in. tall, so they’re easy to push with a foot, cane, crutch, or other device.

Style 8 switches operate with the wave of your hand to reduce the spread of germs. They have an indicator light that changes color when the switch is activated, a selectable unlock time of 1-63 seconds, and a secondary switch that releases doors in the event of a power failure.
