  • Page 13: Fan Speed Modes

    8.3.1 Automatic Fan Speed Mode EasyTouch has three automatic fan speeds available: High, Medium and Low. While in the On Mode, Automatic Fan Speed Mode allows the EasyTouch to determine the required fan speed based upon the set point temperature differential. This permits a balance between the most efficient temperature control and slower, quieter fan speeds.

    FAMU systems therefore must incorporate both cooling and electric heating. EasyTouch supports FAMU operation for both DX and CW systems using the FX2 Control Board, rev J and newer. Please refer to the FX2 Control Board User Manual for further details on how to wire the FX2 control board to a FAMU system (available on the Micro-Air website at this link).

    10. FAULTS There are a total of six different faults that the EasyTouch can declare. Only one applies during CW operation and all six apply during DX operation. When a fault is declared, it is displayed in the Status Area of the Home, Main, FAMU, and System Status screens.

  • Page 20: Low Ac Fault (Dx & Famu Dx Only, No Lockout)

    “LOST AC” Fault History Display: The Lost AC Fault occurs whenever the EasyTouch detects that the AC line voltage has been lost during compressor operation (i.e. a brownout condition). Brownout conditions can cause compressors to stall very quickly (<50ms), so this detection protects the compressor by shutting down the compressor relay output and waiting for the normal fault recovery delay before attempting a compressor restart.

  • Page 21: Easystart Fault (Dx & Famu Dx Only, Contributes To Lockout Count)

    When power is restored, the control resumes operation as last programmed. The EasyTouch also has a battery to supply power to the real-time clock. If the battery has completely discharged or has been removed, only the time and date settings will be lost and will require resetting upon the next power up.
