  • Page 57 Control management When power supply is reset When a unit is powered up, depending on its Auto Start configuration, it will start up with its last operating parameters, or OFF Mode. The EEPROM is available for saving the operating environment of the control in the event of a power-reset condition. If not configured for auto start, at the power up the system will remain in OFF Mode.

  • Page 58: Operating Mode Selection

    Control management Operating mode selection The operating mode is selected based on the command chosen by the remote control. OAT: Outdoor Temperature Cooling Mode WSP: Water Set Point Depending by the system configuration and when the operating mode is cool, the system could operate as follows: With Comfort NUI (CS1).
