7| Fan| Fan speed adjustment . The fan speed is set up in grades by the controller . By pressing the Fan button, the grades can be selected  clockwise in a cyclical way . The current grade selected manually is  indicated by the highlighted bar on the display .
8| Mode| Energy mode selection . The 3 energy modes are Auto, Comfort and Economy . By pressing the Mode button, the user can switch HMI- SG between the 3 modes in a cyclical way . The current mode manually selected is indicated by relevant symbol on the display .

Mounting Considerations

Mounting considerations:

• The device is suitable for semi-flush mounting with a recessed conduit box .
• The unit should not be mounted in recesses, shelving, behind curtains or doors or above or near direct heat sources .
• Avoid direct sun and draught .
• The conduit must be sealed on the device side, as currents of air in the conduit can affect the sensor reading.
• Local installation regulations must be observed .
  Use a flathead screwdriver to gently pry the front covering to access the terminals shown in Figure 2 .

Maintenance

Wipe the display as needed with a damp water only cotton cloth . Do not use any type of cleaner as it may damage the buttons or scratch the display . Do not paint .

Terminations
Daikin Applied recommends using a twisted shielded pair of at least 22AWG for the power wire connections . The shield should be earth grounded only at the power source . Larger gauge wire may be required for long runs .

All wiring must comply with the National Electric Code (NEC) and local codes. Do NOT run any of this device’s wiring in the same conduit as other AC power wiring . Tests show that fluctuating and inaccurate signal levels are possible when AC power wiring is  present in the same conduit as the signal lines .
If you are experiencing any of these difficulties, please contact your Daikin Applied representative .

Adjusting the setpoint
Temporary Setpoint adjustment is performed by pressing the minus (-) and plus (+) buttons and Effective Occupancy must also be set to OCCUPIED or BYPASS .
NOTE: Temporary Setpoint adjustment will not function if the thermostat is in the Program Mode or if the Effective Occupancy is set to STANDBY or UNOCCUPIED .
Pressing the minus (-) or plus (+) buttons will make Area 1 display the current active setpoint value along with the corresponding cooling or heating icon . Area 2 will change from displaying the time to “STPT” .
Subsequent presses of the minus (-) or plus (+) buttons will adjust the setpoint value up or down and will increment by 0 .5 degrees .
Pressing the OK button after changing the setpoint value will confirm the setpoint change.

• If the OK button is not pressed within 10 seconds of the last press of the minus (-) or plus (+) buttons, the change will be discarded and the display will exit the setpoint adjustment state .

Pressing the OK button will then switch the display to the other setpoint value along with the corresponding heating or cooling icon, and allow the user to adjust this setpoint .

Occupancy Indicator

When the Effective Occupancy is set to OCCUPED or BYPASS, then the Comfort Mode Active icon (Area 8) will display .
When the Effective Occupancy is set to STANDBY or UNOCCUPED, then the Economy Mode Active icon (Area 7) will display .

Fan Status & Speed Indicators
NOTE: See Figure 4 to view display references .
The status bar in Area 3 indicates fan speed . Fan speed can be adjusted only on units configured for constant air volume control .

• A single bar indicates the Supply Fan Minimum Speed value .
• Each added bar represents an increase in supply fan speed value . The value is calculated as: Supply Fan Maximum Speed – Supply Fan Minimum Speed / 5 .
• Six bars indicates the Supply Fan Maximum Speed value.

Pressing the FAN button will cause the fan bars to start blinking, indicating that the user is allowed to adjust the fan speed . Each FAN button press will then cycle through the fan speed values .

Press the OK button to confirm fan speed selection.
NOTE: If the OK button is not pressed within 10 seconds of the last press of the FAN button, the change will be discarded and fan speed state will be exited .
