SOURCE: I have a honeywell smartfit

I had exactly the same problem. F4 code says the control valve has jammed --- but it hadn’t.

I ended up having to swap out the room controller and the base unit (I bought the pair since it was winter and I couldn’t ‘eff’ about)

On investigating (well, you have to don’t you?) I could find no obvious fault but did notice that a large electrolytic capacitor was across the actuator motor.

Since these things work by reversing the supply polarity to the motor to drive the actuator one way and the other it strikes me as strange that a polarity sensitive component, one that must be always connecter positive to positive, is used in the way that it is.

Bottom line, tough luck, mate. Replace the units.

New instruction manual for RTH230B


Do you mean the Honeywell RTH230B programmable thermostat? Most of the Honeywell thermostat manuals are available here: http://yourhome.honeywell.com/en/faqs/thermostat . Scroll through the pages to find the RTH230B or use the search feature. The search engine found the installation and user guide in three different languages, see https://yourhome.honeywell.com/en/supportsearch#q=Rth230b . The direct link to the manual in English is https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-1800.pdf .

I hope this helps.

There are other universal replacements but if it was me I would stick with the honeywell parts. I know they are more expensive but in your instance where you already have a problem that is causing the control panels to fail I'm afraid you would make it worse by using other then factory replacements.Thank you
