with a setpoint of 80 degrees, the effective setpoint is 82
degrees. This allows the occupant to have a small amount
of control over raising or lowering the temperature, but
the building owner can still set back setpoints during
standby and unoccupied periods. When the setpoint is in
Hold mode, pressing the icon again releases the hold and
immediately sets the setpoint offset back to 0.
When the TEC is in Min/Max mode (Setpoints/Occ
Setpoint Select are equal to Min and Max Setpoint), the
TEC rejects any attempts to change the present value
outside of the valid range. If the present value is outside
of the valid range (for example, if the Occ Setpoint Select
is switched from Setpoint Offset to Min and Max Setpoint),
the present value is reset to be in the center of the valid
range.
The four modes of setpoint operation are described in
Table 8.

Setpoint
Mode =
Individual
Setpoints
This is the default mode and the original
mode of operation that the TEC was
released with (the next three modes are
new). In this mode, the TEC has a heating
setpoint and a cooling setpoint. There is a
common Setpoint Offset (warmer/cooler
adjust) that applies to each setpoint
simultaneously. The range of setpoint
adjustment is two-fold:
• There are large constant ranges
bounding the individual heating and
cooling setpoints.
• There is also a smaller configurable
range limit set to the Setpoint Offset
point (Control Setup > General > Max
Setpoint Offset).

Setpoint
Mode =
Individual
Setpoints
In this mode, the TEC has a heating
setpoint and a cooling setpoint. Each
setpoint has a configurable range
(Setpoints > Temperature > Min Cooling
Setpoint, Max Cooling Setpoint, Min
Heating Setpoint, and Max Heating
Setpoint). The configurable range values
are bounded by the larger constant
bounds used in Setpoint Offset mode and
are constrained in the following manner:
Min must be below Max and Heating
must be below Cooling, so in order from
least to greatest, the values are: Min
Heating Setpoint, Max Heating Setpoint,
Min Cooling Setpoint, and Max Cooling
Setpoint.
Occ Setpoint
Select =
Setpoint
Offset and

Setpoint
Mode =
Common
Setpoint
In this mode, the TEC has one setpoint,
Common Setpoint, for heating and
cooling. There is also a common Setpoint
Offset (warmer/cooler adjust) that only
applies to Common Setpoint. Otherwise,
this setting works the same as when Occ
Setpoint Select = Setpoint Offset and Heat
Cool Setpoint Mode = Individual Setpoints.
Occ Setpoint
Select = Min
and Max
Setpoints
and Heat
Cool
Setpoint
Mode =
Common
Setpoint
In this mode, the TEC has one setpoint,
Common Setpoint, for heating and
cooling. There is a configurable range for
Common Setpoint, Min Setpoint, and Max
Setpoint.
