Honeywell T7200, T7300 and Q7300 programmable commercial thermostats and subbases control commercial single zone heating, ventilating and air conditioning (HVAC) equipment.
This manual covers the Honeywell T7200, T7300 programmable commercial thermostats and the Q7300 subbase. It describes features such as 7‑day programming, intelligent recovery, fan control, and optional remote sensors, and explains how a single model can serve both single‑stage and multi‑stage HVAC applications.
Detailed sections guide installers through mounting, wiring, DIP‑switch configuration, and system setup, while also providing specifications, electrical ratings, setpoint ranges, battery backup information, and troubleshooting tips. Accessories and recycling notices are included at the end of the document.

Yes, one model can be used for single‑stage and multi‑stage applications.
The battery backup can last up to 60 hours with a fresh 9‑volt alkaline battery.
The subbase DIP switches are set according to Table 5, where each switch controls functions such as stage heat, stage cool, proportional control, fan energizing, and sensor selection.
The thermostat draws a maximum of 6 VA (approximately 0.2 A) at 30 Vac.
