CM Technologies developed a patented electronic system for remotely controlling the glass door of an evaporative cooler.
A remotely triggered module is installed in a roof-mounted electrical box, where the existing manual lock switch is replaced with new locks and an RF keychain remote.
Depending on circumstances, same remote control lock can be operated manually, e.g. with a cable.
In case of electricity shutdown, ICM remote control lock system has an internal battery for remotely opening/locking the ICM for an additional time of 12 hours.
In case of loss of keychain remote, the spare remote control unit can be identified and paired with the main control unit in few seconds.
