Initial settings can be configured via the dipswitches on the circuit board, additional request codes not addressed by RMF-CA200-V1 may
be configured by temporarily connecting an MA remote controller.
Grouping:
The connection of more than one RMF-CA200-V1 to a single thermostat is not supported.
Temperature Sensing:
The RMF-CA200-V1 relies upon both the dry-contact thermostat inputs and Mitsubishi Electric 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 setpoint calculation.
Operate the third-party thermostat per the manufacturer’s instructions. Simultaneous connection and use of RMF-CA200-V1 and Mitsubishi
remote controllers (e.g. MA/ME) is not supported as they will interfere with the correct RMF-CA200-V1 operation. Infrared Wireless remote
controllers may be used for setting fan speed while only G signal is active and setting vane position. RMF-CA200-V1 and thermostat
signals take precedence over Mitsubishi wireless remote controller signals other than fan and vane settings.
Notes:
1.
The indoor unit will limit the internal temperature control set point based on the indoor unit specification.
2.
Only fan speeds available on the Mitsubishi Electric indoor unit can be used by the Thermostat Interface.
3.
Fan and vane control can be set using the Mitsubishi Electric indoor unit’s infrared wireless remote control. Default is Automatic
setting.
4.
When all cooling and 2 hours after heating signals is disabled, energizing G will place the IDU into fan mode. Fan speed may be changed
from default settings using the wireless remote controller and new setting will remain until unit is powered off.
5.
Auto mode function is not supported on multi-zone (MXZ) systems
