T7300E) applications.  
Models available with remote sensor capability.  
(
•
T7300F Thermostats:  
•
Use on single-stage or multistage system in  
conventional or heat pump applications.  
Auxiliary contacts on Q7300 can be used to interface  
with C7400/W7459 Economizer System for total  
integration of rooftop control.  
•
•
•
Remote temperature sensors available for use with  
all models.

Q7300 Subbase:  
APPLICATION  
•
•
Use with T7300D,E,F Thermostats.  
Auxiliary contacts can be used to interface with  
C7400/W7459 Economizer System for total integration  
of rooftop control.  
The T7200, T7300 Thermostats and Q7300 Subbases control  
2
4 Vac commercial single zone heating, ventilating and air  
conditioning (HVAC) equipment. In addition, the Q7300H  
Communicating Subbase can communicate schedule  
information and system instructions to other devices in a  
LONWORKS® network.  
•
•
•
When used with the T7300F (revision 4 or later), the  
Q7300H communicates with other network devices.  
Q7300L two stages of heat control ML7984 and V5011/  
V5013 valve: stage 1 opens valve 40%; stage 2 100%.  
Q7300L provides two-speed fan control:  
—
Low: heat and occupied fan.  
FEATURES  
— High: cooling.  
All Models:  
•
•
•
7-day programming.  
Two Occupied and two Unoccupied periods per day.  
Individual heat and cool setpoints available for  
Occupied and Unoccupied periods.  
Proportional plus Integral (P+I) control eliminates  
temperature fluctuations.

possible and do not run thermostat wires adjacent to  
the line voltage electrical distribution systems. Use  
shielded cable (Belden type 8762 or equivalent for
