DestBypass Bypass state of one node may be shared with bypass state of another node using DestBypass and SrcBypass.
This allows a wall module at one node to be used to override the scheduled occupancy of another node. The
node with DestBypass bound normally does not have a wall module. See the StatusOcc and StatusOvrd for
more details. When a bypass signal is received via DestBypass, the bypass timer is not used. It is assumed
that the duration of the bypass period is managed at the DestBypass source node. Valid states are as follows:

DestDlcShed Input from an energy management system that monitors the building energy consumption. Controls the space
temperature to save energy when the total building demand is approaching a limiting threshold.
DestFan DestFan and the thermostat front panel fan switch control the operation of the fan. The last item updated
(DestFan or thermostat front panel fan switch) determines the fan operation. The fan may be in Auto mode
defined by FanMode or may be continuously on.
Allowable states:

DestRmTempSpt Input network variable that can be used to determine the temperature control point. If DestRmTempSpt is
invalid, then this step is skipped.
DestRmTemp Room temperature provided by a sensor on the network.
DestDate DestYear, DestMonth, DestDate are the date input values.
If DestYear is 0xFFFF and DestMonth is 0xFF, then DestDate is the day of week as shown below:
If DestYear is not 0xFFFF and DestMonth is not 0xFF, then DestDate is the day of month. The node uses
DestYear, DestMonth, and DestDate to calculate the day of week using a perpetual calendar. The thermostat's
internal time clock only keeps track of day of week.
Table A5. Shared Points (Right).


On The node should bypass the time-of-day schedule (subject to occupancy arbitration logic).
Null The input is not available because if it is not bound, the input is no longer being updated by the
sender, or Bypass is no longer called. This is the same as Off. 

Off or Undefined The node should not bypass the time-of-day schedule.
On The node should not bypass the time-of-day schedule. If the node receives this combination of state
and value, then state is set to Off.

ON If the thermostat allows Auto mode, the fan operates according to the FanMode selection. If the

thermostat does not allow Auto mode, the fan runs continuously.
OFF If the thermostat allows On mode, the fan is continuously on. If the fan does not allow Continuously

On, then the fan operates according to the FanMode selection.
NULL DestFan does not affect the fan operating mode of the thermostat.
When StatusMode is Off, Disabled, FanOnly, or Manual, DestFan has no effect .
0 = Sunday; 1 = Monday; 2 = Tuesday; 3 = Wednesday; 4 = Thursday; 5 = Friday; 6 = Saturday.
