It should be showing the 1/2 degree. I don't see anything in the manual that alows you not to see that. You probably have a defective unit.

The Honeywell RT2300/RTH221 do not work with most baseboard heating systems. The thermostat works with 24V heating systems. Most baseboard systems are 120V or 240V.

I wish that I had better news for you. You can see the specifications at the Home Depot product site (for one version of the RTH2300) here: https://www.homedepot.com/p/Honeywell-5-2-Day-Programmable-Thermostat-with-Backlight-RTH2300B/203539496 .

have you read the manual?

Honeywell... | Answered on Sep 02, 2018 | 305 views


Keep in mind you have the same terminals on the damper. 1-4-6. be sure both board and dampers are wired the same for spring open/power closed. I cant remember if that 311 sends power with a call or not( if power is being sent when light is on), but once you have double checked the damper wiring either verify with a meter that power is being sent or verify air flow. if it is then backwards simply reverse wires on board. I suspect it sends power when light is on, that is why zone 3 is lit. (there is no call for cooling on 3, therefore it is shutting the damper) YES, the damper that is not really there. Let me know, hope this helps. The damper that is trying to cool should NOT be getting any power, wire accordingly.

Since there are no manuals on line I would probably say there are screws on the back and bottom of the unit to take it apart? It should be taken apart by a professionals
