PAGE DESCRIPTION The status information that can be viewed on each page is dependent on the type of equipment being operated and the current status of the equipment. For example, a make-up air unit will not have a minimum position. The CRD can be enabled to allow for the adjustment of setpoints, such as the discharge air temperatures, or the outside air damper minimum position, turn the equipment on or off, and set the occupied or unoccupied schedule. -
Page 9: Discharge Temperature And Setpoint
Cooling Describes the number of cooling stages as a percentage. For example, if the equipment has 3 compressors the output will indicate 33, 66 and 100%, as well as indicating the return signal (on or off) to confirm cooling is operational. Economizer Indicates the actual C-TRAC3 economizer output to the dampers (%) as well as indicating the return signal (on or off) to confirm dampers are operational. - Page 10 10 of 12 Nov 10...
