DuctTempEnable If the thermostat has duct temperature sensor capability and a duct sensor is connected, ductTempEnable is
True and duct temperature is reported in StatusDuctTemp. If ductTempEnable is False, StatusDuctTemp is set
to invalid. When DuctTempEnable is False, the DuctTempSenErr is suppressed.
EmHeatCycHr 3,4,6,8,9 Cycles Per Hour For the emergency heat stage(s).

FanKeyDisabled False

FanMode Specifies the operation of the fan. This network variable field sets the intelligent fan mode parameter in the
T7300 (Installer Setup Parameter No. 17). Valid values are:
FanOnHeat FanOnHeat specifies the operation of the fan during Heat Mode. This network variable field sets the Fan
Option for Dual Fuel parameter in the T7300 (Installer Setup Parameter No. 2). Allows choice of either the
T7300 directly starting the fan, or the plenum temperature switch starting the fan. Typically, with gas or oil fuel,
a plenum switch is used, and with electric heat, the T7300 controls the fan directly. Valid values are:
FanRunOnCool FanRunOnCool sets the Extend Fan for Cooling parameter in the T7300 (Installer Setup Parameter No. 19).
This parameter specifies whether or not the fan runs for a short time after the cooling stages have turned off. If
FanRunOnCool is True, the fan is turned off 90 seconds after all cooling stages have turned off. If
FanRunOnCool is False, the fan is turned off immediately when the last cooling stage is turned off.
FanRunOnHeat Sets the Extend Fan for Heating parameter in the T7300 (Installer Setup Parameter No. 20). This parameter
specifies whether the fan runs for a short time after all the heating stages have turned off. If FanRunOnHeat is
True, the fan is turned off 90 seconds after the heating stages have turned off. If FanRunOnHeat is False, the
fan is turned off immediately when the last cooling stage is turned off.
HeatCycHr1 3, 4, 6, 8, 9 Cycles Per Hour for heat stage 1.
HeatCycHr2 3, 4, 6, 8, 9 Cycles Per Hour for heat stage 2.
HeatCycHr3 3, 4, 6, 8, 9 Cycles Per Hour fFor heat stage 3.
HeatOccSpt NciSetpoints specify the scheduled space temperature setpoint for various operating modes and effective
occupancy. Setpoints may be changed during day-to-day operation of the node by a networked operator
interface. When the local schedule is active, nciSetpoints can also be changed from the front panel of the
thermostat. The fields specify the setpoint temperature for heating and cooling modes and effective occupancy
(Occ, Standby, or UnOcc).
HeatStbySpt NciSetpoints specify the scheduled space temperature setpoint for various operating modes and effective
occupancy. Setpoints may be changed during day-to-day operation of the node by a networked operator
interface. When the local schedule is active, nciSetpoints can also be changed from the front panel of the
thermostat. The fields specify the setpoint temperature for heating and cooling modes and effective occupancy
(Occ, Standby, or UnOcc).
Table A2. Configuration Points (Right Continued).

Installer parameter has a 0 state; True
Auto only.

AutoFan Fan cycles on and off with demand for coolng and may cycle with heating if FanOnHeat is True.

This is called intermittent operation.
ContFan Fan runs continuously when the effective occupancy is Occ or Bypass. When the effective
occupancy is UnOcc, the fan cycles on and off with demand for cooling and may cycle with heating if
FanOnHeat is True. 
ContFanRecov Fan runs continuously when the effective occupancy is Occ or Bypass and when the
T7300 is in Recovery mode. When effective occupancy is UnOcc (with no recovery in progress), the fan
cycles on and off with demand for cooling and may cycle with heating if FanOnHeat is True.


True Fan is on in Heat StatusMode.
False Fan is never turned on in the Heat StatusMode and a thermostat controlled switch that senses
heated air temperature turns on the fan.
