Honeywell Home C7735A1000/U Return Duct: Backup Control of Non-Zoned RedLINK®-Enabled

The C7735A1000 is a return duct sensor from Resideo (Honeywell Home), for backup control of non-zoned RedLINK-enabled systems.

It mounts in the return duct and gives the system a temperature to fall back on. If the wireless link to the thermostat drops, the equipment does not simply stop — it holds the house on the duct reading until the thermostat comes back. That is the difference between a lost signal and a no-heat call in January.

Rated 0 °F to 200 °F.

Goes with: TH6320R1004, TH5320R1002.
