Series 2000 Programmable Commercial

APPLICATION

The T7200, T7300 Thermostats and Q7300 Subbases control
24 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.

FEATURES

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.
• Intelligent Recovery® control automatically optimizes
equipment start times based on building load.
• Intelligent Fan™ feature energizes fan continuously in
the Occupied periods. Fan can also be configured for
conventional heat or electric heat fan operation.
