NETWORK CONFIGURATIONS
The T7350H can be configured to perform a variety of activities in which data is sent to and/or received from other nodes on the L ON W ORKS® network. Information that can be shared with other network devices includes:
— Current year, month, day, hour, minute, second.
— System mode (HEAT, COOL, AUTO, OFF, EM HEAT).
— Current fan setting (ON, AUTO).
— Space temperature.
— Space relative humidity.
— Discharge air temperature.
— Outdoor air temperature.
— Occupancy sensor status.
— Terminal load.
— Current setpoint.
— Occupied/Unoccupied schedule commands.
— Current occupancy status.
— Occupancy schedule including current occupancy state, next state and time in minutes until next scheduled change of occupancy state.
— Relay status (heat/cool stages and fan).
— Alarm status.
— Alarm log including the last five alarms.
— Device Error status.
— Bypass state (multiple XL10 devices follow the bypass operation of a master device).
A network configuration tool is used to configure the T7350H
Thermostats and other nodes with which the T7350H interacts. The following is a brief description of the configurable features that can be commanded over the network:
• Time Master:
When a T7350H is designated as the network time master, the current time of day and date is synchronized across the network every minute. The L ON S PEC ™ T7350H General
Screen can be used to configure a T7350H as the Network
Time Master. Whenever the time of day or date of the time master is changed, it automatically adjusts all the other network devices (T7350H, Q7300 & XL15A) bound to the time master. When a T7350H is controlled by a time master, the local day light saving schedule is disabled. The
Day Light Saving option on all time master recipients should be disabled. This prevents erroneous time changes
(local daylight savings switchover) during temporary network outages.

the user is not prevented from making local schedule changes at the recipient thermostat. Local schedule changes (at a recipient device) have no effect on the scheduling commands received from the master device.
When a T7350H is designated as a master schedule device, it sends its schedule information (current state, next state, time until next change of state) to the appropriate T7350H(s) which, in turn, overrides any existing internal time schedule. The T7350H Thermostat can provide master scheduling information to multiple
Excel 10 devices. One T7350H shares the schedule information (current state, next state, time until next change of state) with the designated Excel 10 devices.

• System Mode Settings:
System mode settings (HEAT, COOL, AUTO, OFF, EM
HEAT) can be commanded by a remote T7350H or other compatible XL10 device. A one to many network binding can be used to command multiple devices from a single unit. In addition, a network connected Workstation can be used to change the System Mode.

• Fan Settings:
Fan settings (ON, AUTO) can be changed from a network connected Workstation.

• Outdoor Air Temperature Sharing:
If a valid outdoor air temperature value is received at the
T7350H OAT network variable input, that value will be used in the T7350H. The local OAT sensor of the T7350H is ignored until the network sensor fails.

• Time Schedule:
The occupancy schedule used by a T7350H may reside locally in that device or remotely in another schedule device (T7350H, XL15a, XL15b or T7300/Q7300). Local schedules can be created and modified using the T7350H keypad, a direct connected PDA, a network connected configuration tool (L ON S PEC ™) or Command Display.
External schedules can also be modified using the keypad of the master schedule device, or with a network connected configuration tool or Workstation. When a
T7350H receives scheduling information over the network,

• Discharge Air Temperature Sharing:
The discharge air temperature value can be shared with other devices on the network. Note that the T7350H does not accept a network discharge air temperature input.
