Honeywell Home TH6210U2001/U — T6 Pro programmable thermostat for up to 2 heat and 1 cool heat pump systems, or 1 heat and 1 cool conventional systems.
The T6 Pro is the contractor-grade programmable tier of the T Series, between a basic non-programmable stat and the connected T6 Pro WiFi. It runs a local schedule only: no radio, no app. It mounts on the same UWP wall plate used across the T Series.
- Up to 2 heat / 1 cool on heat pumps, or 1 heat / 1 cool conventional
- Only one compressor stage is available on the TH6210U
- Selectable 7-day, 5-2-day, 5-1-1-day programmable, or non-programmable
- Runs on R and C; two AA batteries are supplied, so a C wire is recommended but not mandatory
- Heat setpoint 40 to 90 °F, cool setpoint 50 to 99 °F
- Includes the UWP mounting system, cover plate, screws and anchors
Three models share one installation document. TH6220U2000 and TH6320U2008 add stages and accept a wired outdoor sensor, which the TH6210U does not. The T6 Pro WiFi models are a separate connected product and do require a C wire. The trailing /U is a packaging suffix, not a different thermostat.
