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 .

Layout

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 .

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 .
