surface. Double-sided tape may be used to affix the device. When using tape, ensure that the tape is approved for use within the
anticipated operating temperature ranges.
Install the transformer, as necessary, per building code and manufacturer's installation instructions.

Connect the RMF-CA100 cable to the connector CN105 on the indoor unit control board.
3.
Connect RMF-CA100 terminals using 18 AWG wire.

Device Configuration
Initial settings can be configured via the dipswitches on the circuit board, SW1 and SW2 (not used). The circuit board can be accessed by
unfastening the four screws on the back of the case.
Additional request codes not addressed by the thermostat interface may be configured by temporarily connecting an MA remote controller.
Grouping
The connection of more than one RMF-CA100 to a single thermostat is not supported.
Temperature Sensing
The RMF-CA100 relies upon both the dry-contact thermostat and the indoor unit's thermistors in order to monitor room temperature. The
thermostat senses room temperature and establishes set temp. The Mitsubishi Electric indoor unit's return air thermistor is used for cooling
and heating calculation.
