Mitsubishi Heavy Industries Air Conditioning Eco Touch Introduction

The Mitsubishi Heavy Industries air conditioning RC-EX1A Eco Touch is a touch screen wired controller providing full function control and more than 90 function settings for your air conditioning system. Using the wired remote control system, users can run and stop the unit, switch operations, adjust the temperature, fan speed and air flow direction (up or down), and control timer operations. Compatible with Mitsubishi Heavy Industries air conditioning systems FD Series split Systems, Multi Systems, and KX Systems. The Mitsubishi Heavy Industries Air Conditioning Eco Touch Data In Operation Mode: The Eco-Touch wired remote controllers have some excellent features giving the user and the air conditioning installation engineer the ability to show operational data that can be collated for commissioning purposes. The data available through the "operation data" menu includes: Refrigerant pressure, outdoor air temperatures, compressor speed, compressor  running current, compressor Hz, discharge pipe temperature, indoor unit operating hours, outdoor unit heat exchanger temperature, indoor unit heat exchanger temperature, fan speed, set temperature, remote control temperature and return air temperature. Standard password is 9999 to access the various menus. Useful data for service engineers. In addition, the Eco Touch wired controllers show Error Codes using the CHECK button.
