Yesterday, while at home all day puttering about decorating the house for the holidays, I was thinking about how nice it would be if the thermostat in our parlour actually worked.  

For the last few years, the heat has been a turn it on or turn it off deal.  We replaced the thermostat, thinking that was the problem.  New thermostat hooked up according to the manufacturer's instructions, with no change in the situation.  Except the heat turned on and off on the opposite switches.  Flame icon for off, snowflake icon for on.  That was a couple of years ago.  We've had four different people looking at the wiring on the zone valves, and none of them could figure out what the problem was.

So I tweeted for help.

A tweep referred me to a new tweep who started messaging me with troubleshooting suggestions.  The first thing he mentioned, was the wiring of the thermostat.  I sent him a picture of how the wiring was done.  He suggested moving a wire from the B position to the W position.  I turned off the power, made the switch, turned the power back on, and my heating system has been working perfectly since.  

I can't believe we've been going so long without ever thinking it could be so simple a fix.  And Sam Boone (McLoughlan Supplies in Grand Falls-Windsor), you are a star!  Thank you thank you thank you!
