APPLICATION  
The T7300F Series 2000 Commercial Thermostat and  
Q7300H Communicating Subbase control 24 Vac commercial  
single-zone multistage heating, ventilating and air conditioning  
Keypad lockout available.  
Auxiliary contacts can interface with C7400/W7459  
Economizer System for total rooftop control  
integration.  
(
HVAC) equipment. Additionally, the Q7300H Subbase allows  
remote access and the sharing of clock, schedule, setpoints,  
bypass and other system parameters with other devices in a  
LONWORKS® network.  
Q7300H  
Provides networking capability on a LONWORKS Bus  
using a Free Topology Transceiver (FTT).  
Conforms to LONMARK® thermostat functional profile.  
Dial-in capability allows remote monitoring and control  
of key variables such as time, schedule, setpoints,  
mode, fan status.  
Communicates schedule information to other network  
devices.  
Selects fan operation and system mode using a remote  
T7300F Thermostat.  
Shares information such as time-of-day, temporary  
setpoint and occupancy status with multiple T7300 or  
Excel 10 controllers.  
Installer setup may be done locally from the T7300  
keypad or from a local or remote personal computer.  
Fully integrated with Honeywell's light commercial  
building solutions to provide enhanced alarming,  
trending, scheduling and dial-out capabilities.
