9. Mode Functional Description
• Cool Mode
• Select the Cool function from the menu by touching the
MODE
icon on the main screen (see Figure 1)
• Select
FAN SPEED
from the menu by touching the
FAN
SPEED
icon on the main screen then selecting High,
Medium, Low, or Auto (see Figure 2)
• The unit will run according to the default settings in Table 3 if
the user has not altered any settings
•
Temporary Override:
The user can change the temperature
setting temporarily by touching the “+” or “-” icon on the
main screen to get the expected temperature settings. The
“+” and “-” icons appear after the user touches the screen.
The temporary override setting will be effective once the user
has not touched the screen for more than 3-seconds;
(Figure 3)
• The temporary override setting will only apply to the time
period between the input and the next temperature pre-
loaded in the programmed weekly schedule.
• The
Temporary Override
will be shown on the screen, to
indicate the new setting is different with the setting that
set in the weekly schedule; and will not disappear until the
applicable time period has passed
• The color of the temperature value and temporary override
text will be white when the setting is equal to the ambient
temperature, it will be blue when the setting is lower than
the ambient temperature, and it will be orange when the new
setting is higher than the ambient temperature
• Temperature Range: 51°F to 91°F

* To set various dip switch status to get suitable functions as below Table 2.
Notes:
J1: If the unit has any heating function, then J1=ON; J1=OFF in cooling only
applications.
J2: If the user does not want “7-day programing function,” then J2=OFF. With J2=OFF,
the thermostat functions like a simple thermostat.
J3: The thermostat needs to know what type of heating is present. If the unit is using
hydronic heating coil for the heating function (such as PTAC with hydronic heating
coil or Hydronic WSHP), then J3=ON.
J4: For 2-speed fan operation J4=ON; for 3-speed fan applications J4=OFF.
J5: Refer to Table 5 for details.
J6: J6=ON is the default. J6=OFF is a test/service function option.
J7: There are two ambient temperature sensors in total, one is inside the
thermostat A, the other is inside the unit. This switch is to set which sensor the
customer is going to use.
