Event Max Cool Setpoint (setup step 54)
Event Min Heat Setpoint (setup step 55)
Specifies the range of allowable setpoint adjustments to be enforced when any ADR signal has been received from the utility. Since you might be paying more for energy while an event is active, you can impose tighter limits on setpoint ranges that are only enforced during the even
Static Cool Setpoint (setup step 56)
Static Heat Setpoint (setup step 57)
Specifies the setpoints that will come into use during an event when the ADR ACTION is set to OBSERVE STATIC SETPOINTS
Cool Setpoint Offset (setup step 58)
Heat Setpoint Offset (setup step 59)
Specifies how much the current setpoints in effect prior to an event will be altered during an event when the ADR ACTION is set to OBSERVE SETPOINT OFFSETS. The heat setpoint can be automatically lowered by -1 to -15 degrees while the cool setpoint can be automatically raised by 1 to 15 degrees
DISPLAY INDICATIONS WHEN AN ADR EVENT IS HAPPENING
After setting your desired values for use during an ADR event, the scrolling display will give a little information when an event is pending or active. For instance, when an ADR event has been sent to your thermostat, you might see ADR STARTS 8/14 at 2:00pm to notify you of a pending event. Once active, you might see ADR STOPS 8/14 at 6:00pm.
