WARNING ‐ INCORRECT HANDLING CAN RESULT IN ELECTRICAL INJURY, DEVICE MALFUNCTION AND DAMAGE
THOROUGHLY READ THE FOLLOWING SAFETY PRECAUTIONS BEFORE EACH USE OF THIS PRODUCT (THE "DEVICE").
Do not expose the device to, or immerse the device in, water. Doing so could lead to electrical shock to a person, device malfunction or
•
device 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 to a person, device malfunction and device 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 device 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 qualitied 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.
In Conventional or HEATPUMP mode,
•
connector on indoor units that have CN24 connector and is preferred method. The CN24 connector outputs 12VDC at 80mA. For
units without CN24 connector, Auxiliary convectional heater control is provided by RMF-CA200-V1 output signal O which outputs
24VAC when active.
SINGLE or 2 STAGE OPERATION MODE SELECTION
1. Select 1 or 2 stage thermostat operation using dipswitch 1-1:
OFF position (default)
ON position
2. Select Conventional or Heat Pump Mode using Dipswitch 1-2
