Temperature Setpoints
The thermostat controller provides a flexible setpoint configuration to give power to the building owner while being
easy to use by the occupant. In addition to a simple up/down offset adjustment on the home screen for the
occupant, there are six temperature setpoints on the TEC. The six temperature setpoints are Cooling and Heating
setpoints for Occupied, Unoccupied, and Standby modes. To set these setpoints:
1.
Press the
Menu
icon.
2.
Press
Setpoints
.
3.
Select the setpoint to adjust and change as desired.
4.
Press
to save and
to return to the previous screen.
Note:
The TEC enforces a 2-degree deadband between heating and cooling setpoints. If a setpoint violates this
standard (for example, cooling setpoint is set to 70 with a heating setpoint already set to 70), the opposing setpoint
is modified to comply with this deadband (in the previous example, the heating setpoint would automatically
change to 68).
The occupant has access to an up/down adjustment from the home screen. This adjustment applies a fixed offset
(+/-) to the currently active setpoint, and this offset holds until the occupancy state of the controller changes. If the
user taps the setpoint on the home screen, the icon inverts and displays white text on a black icon. The offset is
held throughout all occupancy periods. For example, if the TEC is cooling in Occupied mode to an occupied cooling
setpoint of 72 and you raise the setpoint 2 degrees to 74 from the home screen and then select
hold
, then the +2
degree offset persists through an occupancy change. If the occupancy then changes to unoccupied, 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.
