Signal Decoding

The 'package' of instructions sent to the RCM is decoded and read by the microprocessor chip on the RCM board. The first part of the 'package' sent by the control contains the channel identification code, which is then compared to the 'set ' channel number of the RCM.

Channel Recognition

Once the RCM board has recognized the transmitted 'package' as having the matching channel number, the rest of the information is allowed to pass to the microprocessor chip.If the transmitted channel number does not match the fans own number the rest of the 'package' instructions are ignored. This allows many different fans to be run in the same room (using different channels), all operated independently from their owm W-21 remote.

Channel Number Storage

The channel number assigned to an individual fan is contained in a NOVRAM chip on the RCM board and can be changed by the remote control using a special "start-up" procedure. The channel number is 'burnt' into the NOVRAM chip so that its memory is not lost when the power is turned off.

Auto-speed

In order for the auto-speed mode to operate and make changes to the fan speed the control signal is sent automatically whenever the temperature changes enough to require a speed increase or decrease.

NOTE: In auto-speed mode an increase or decrease in temperature of approximately 1.5°F will cause the fan to increase or decrease speed by one step

Normal Operation

When the fan is not set in the auto-speed mode the instruction 'package' is automatically sent every thirty minutes to keep the fan operating correctly. This feature is especially convenient if you have left the fan in the 'security mode' as it resets the fan to the pre-set operating setting even after a complete power failure!
