2. Safety Precautions
THOROUGHLYREAD THE FOLLOWINGSAFETY PRECAUTIONS BEFORE EACH USE OF THIS PRODUCT (THE “DEVICE”).
WARNING – INCORRECT HANDLING MAY RESULT IN INJURY, MALFUNCTION AND / OR DAMAGE TO DEVICE
• Do not expose the device to or immerse the device in water. Doing so could lead to electrical shock, device malfunction or damage.
• Do not install the device in a bathroom, kitchen, or any room where steam could form. Condensation could develop on or around the device and
cause electrical shock, device malfunction or damage.
• Do not install the device in a location where a gas leak could occur.
• Do not expose the device to heat or radiation, including direct sunlight, or install the device in a location where the temperature could be greater
than 40°C (104°F) or less than 0°C (32°F). Doing any of these things could result in device deformation or malfunction.
• Always ensure the device is installed in an area without exposure to high frequency noise.
• Power generators, inverters, and high-frequency or radio communication equipment may interfere with the operation of this device.
• All electrical work should be performed by a qualified technician and in accordance with applicable laws and the instructions outlined in this
manual.
• Use standard wiring with the proper current capacity to avoid current leak, excessive heat, and fire.
• Use only specified cables and wiring; securely connect each so that the terminals do not bear any weight.
• Include slack in the power supply wiring. Tension in the wiring may cause it to excessively heat up and break, which could result in a fire.
• Improperly connected or short-circuited cables or wiring may produce heat and cause device malfunction, device damage, and fire.
• Capacity shortage to the power supply circuit or improper installation may result in electrical shock or fire.
• Do not modify or alter this device or cable in any manner whatsoever.
3. Installation
Thermostat may be configured to operate in conventional or heat pump modes. Use 18 AWG thermostat wire for all connections.
• Wire connection terminals support 20-30VAC.
• G1, G2, G3 Thermostat fan signals are not supported.
• The default fan speed can be set to high, medium, low and quiet speeds using dipswitches. While in FAN mode (only G signal active) the Mitsubishi
Electric indoor unit wireless remote controller can be used to adjust the fan speed from the initial default setting to any other fan speed. The RMF-
CA200 will retain the new settings until the unit is power cycled at which point it will resume with default dipswitch speed setting.
• The default vane position can be set by using dipswitches. The default vane position can be changed by using the Mitsubishi Electric indoor unit
wireless remote controller to any other desired vane. The RMF-CA200 will retain the new vane position until the unit is power cycled at which
point it will resume with default dipswitch vane setting.
• Convection auxiliary heater control is provided by CN24 connector on indoor units PC Board. The CN24 connector outputs 12VDC at 80mA. If
system does not provide CN24 connector, connect auxiliary heat control directly from thermostat to auxiliary heat source. Any connection to an
auxiliary heat source is outside the scope of Mitsubishi Electric products. Please consult a licensed technician to ensure proper set-up and safety of
auxiliary heat source in accordance with auxiliary heat source product documentation and local building codes.
• The device provides two mounting holes to mechanically affix the case to a solid 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 per Canadian Electrical Code, Canadian building code and local codes compliance, and manufacturer’s installation
instructions.
• Connect the RMF-CA200-V1 cable to the connector CN105 on the indoor unit control board.
STEP 1: Select 1 or 2 stage thermostat operation using dipswitch 1-1:
OFF position (default) Configured for 2 stage heating and cooling thermostats (Y1, Y2 & W1, W2)
ON position Configured for use with single stage heating / cooling thermostats (Y1, W1)
