Fig. 1 — TEMP System Thermostat Functions
System Displays —
The TEMP system thermostat has
a display window which is used to show system information
and for programming mode. See Fig. 1.
SET POINT DISPLAY — The heating and cooling set points
are shown in the display window during the normal display
mode. The heating and cooling set points are used to deter-
mine the range of temperatures that are maintained in the
zone.
The cooling set point buttons are located on the left side
of the display screen. The heating set point buttons are lo-
cated on the right side of the display screen.
MODE DISPLAY — When the system fan is energized, the
word FAN appears on the display screen.
When the cooling mode is energized, the word COOL ap-
pears on the display screen. The system fan will also be en-
ergized.
When the heating mode is energized, the word HEAT ap-
pears on the display screen. The system fan will also be en-
ergized, unless it is configured not to run during heating mode.
If the system enters IAQ (Indoor Air Quality) mode, the
word IA9 appears on the display screen.
ALTERNATE DISPLAY — By pressing both cooling or heat-
ing set point buttons simultaneously, the alternate informa-
tion display is activated. The TEMP system thermostat will
display the current zone temperature and then the time of
day. If the Alternate Display function has been configured to
ON, the TEMP system thermostat will show more detailed
zone information. The display will then return to normal.
Adjustment of Set Points —
ing set points are configured through the set point buttons.
The heating set point buttons are located on the right side
of the display screen. Press the upper button to raise the heat-
ing set point temperature. Press the lower button to lower
the heating set point temperature. The heating set point is
limited to a range of 66 to 80 F by the TEMP system.
The cooling set point buttons are located on the left side
of the display screen. Press the upper button to raise the cool-
ing set point temperature. Press the lower button to lower
the cooling set point temperature. The cooling set point is
limited to a range of 66 to 80 F by the TEMP system.
NOTE: The heating and cooling set point ranges can be con-
figured to smaller ranges.
The heating and cooling set points may be set for the same
temperature, but the thermostat will not allow the cooling
set point to be adjusted lower than the heating set point, or
the heating set point to be adjusted higher than the cooling
set point.
Operating Modes —
3 operating modes: occupied mode, unoccupied mode, and
unoccupied override. Occupied mode is the mode used when
the area is normally occupied. Unoccupied mode is used to
conserve energy and is used when the area is normally un-
occupied. Unoccupied Override is used to temporarily over-
ride unoccupied mode when an area is in use during the un-
occupied schedule time. The user can manually activate
unoccupied override. Set points can be adjusted during both
occupied and unoccupied override modes.
The occupied schedule controls when the zone is in oc-
cupied or unoccupied mode. The schedule can be sent from
a device over the network, or it can be programmed at the
TEMP system thermostat.
UNOCCUPIED OVERRIDE — Unoccupied override is used
to temporarily change the system set points to the occupied
mode set points. An example of unoccupied override would
be a worker staying past 6:00 PM to finish a job when the
scheduled unoccupied time is 6:00 PM.
To override unoccupied mode, press a set point button.
The unoccupied display will be replaced with the occupied
mode display. The TEMP system thermostat will automati-
cally return to unoccupied mode when the override timer
expires.
