About 3 months before the batteries are exhausted, the battery symbol appears on the display, but all functions will be fully maintained. When changing the batteries, the current data will be retained for a maximum of one minute.

The REV24 has a plastic housing with a large display and easily accessible operating elements. The controller is removed from its base by sliding it upward. It is thus possible to replace the two 1.5 V alkaline batteries type AA in the compartment at the rear of the controller.

The base can be fitted to most types of commercially available recessed conduit boxes or directly on the wall for wiring. The base only houses the terminals for the electrical connection between the controller and connected devices. The entire electronics (including the relay with a potentialfree changeover contact) are accommodated in the controller.
