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. 

• 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, 

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.

• 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.

• Space Temperature Sharing: 

If a valid space temperature value is received at the 

T7350H Space Temperature network variable input, that
