In other words, this user address inthe Time Program controls the occupied/unoccupied mode of the system. A logical 1is occupied; a logical 0 is unoccupied.NOTE:If the datapoint is not directly connected to the control icon via drag and drop(possible since Care 8.01.00), the Tuncos icon must be added between thedatapoint and the EOV.X2 (Tset, Excel Web / Excel Web II) is a room temperature setpoint. You can enterX2 as a point or parameter (engineering unit index number and a value).X3 (TRm, Excel Web / Excel Web II) is the room sensor input.X4 (TOat, Excel Web / Excel Web II) is the outdoor air temperature (OAT) sensor.XD5 (Mode, Excel Web / Excel Web II) sets the mode of operation, heating orcooling. Heating is 1; cooling is 0. You can set XD5 from a switching tableevaluation of the heating and cooling outputs from ZEB.Outputs One through three digital outputs (YD1 through YD3).YD1 (OnOff, Excel Web / Excel Web II) commands system start-up (1) andshutdown (0). This output is required.YD2 (OptOn, Excel Web / Excel Web II) is logical 1 during system start-up.Otherwise, it is 0.
