OUTSIDE AIR TEMPERATURE RESET
The control system is capable of temperature reset based on
OAT. Typically as the outdoor temperature decreases so does
building cooling load. The chilled water temperature can be in-
creased to lower energy usage while still meeting load demand.
To use OAT Reset, four variables must be configured: Cooling
Reset Select, OAT No Reset Value (outdoor temperature at
which no reset is required), OAT Full Reset Value (outdoor
temperature at which full reset is required), and Cooling Reset
Deg Value (the amount of temperature reset desired).
To configure this option with the Carrier Controller display:
In the example in Fig. 39, the OAT reset provides 0°F (0°C)
chilled water set point reset at 85°F (29.4°C) OAT and 15°F
(8.3°C) reset at 55°F (12.8°C) OAT.
