Mitsubishi Thermostat Interface - PAC-US444CN-1

The Mitsubishi Thermostat Interface uses a patent pending algorithm to vary the INVERTER-driven compressor capacity and save energy. It can accomplish this by setting up and wiring a thermostat for a conventional system control with two stages of heating and cooling. Third party thermostats or input/output controllers can control the indoor units fan speed to three different levels: high, medium, and low.

• Auto recovery after power failure
• INVERTER operation settings: Optimized variable capacity (Preferred)
• Set fan speed in thermal off for heating mode
• Set Fan & CN24 operation during Defrost
• Static Pressure Adjustable Setting
• Fan Speed: Auto, Medium, High, and Custom Auto
• Delayed Off Adjustable Setting: 0, 5 (default), 10, or 30 minutes
• Connection: CN105 - IT Terminal
• Addressing: No addressing required
• Provides 3 input terminals to control fan speed control: High, Medium, and Low
• Indoor unit modes: Cool, Heat, Fan, and Off
• One Thermostat Interface per indoor unit
• Allows a HVAC Thermostat or I/O Controller to control a Mitsubishi Electric Cooling & Heating CITY MULTI or M-Series or P-Series indoor unit
