On rotary thermostat, now have to turn dial lower to get heat
Why would this be happening? I had to put my old rotary thermostat back on after having a digital Honeywell programmable thermostat hooked up to my gas-fired hot water heat, and now the heat kicks on only when the dial is turned lower. It's a simple two wire system, and I tried switching the wires back and forth but it acts the same either way. This is going to make setting the thermostat fairly tricky!

What happened with the digital themostat?
I noticed that you are a renter. Probably, you should ask your landlord to replace or fix thermostats, etc.

To make a long story short (see my other threads for more info), the boiler isn't working properly, but the landlord feels the digital thermostat was to blame. Even though it makes little sense, i had to take off the programmable thermostat and put back on the crappy rotary mechanical one. The rotary one was also a simple two-wire thermostat, so there weren't any other places to put the two wires than where I did. What is happening is basically it's as if the temperatures were flipped - if you set the heat to 90 the furnace is off. But, as you slowly lower the set temp eventually it turns on, and it stays on even if you go all the way down to 50. So it's as if it is backwards for some reason. Yes, I should not have installed the digital thermostat without asking, but it also is clearly not to blame for the furnace acting up, as it acted exactly the same without any thermostat attached and the two wires simply twisted together.

Ha! No, I wish it was that simple. The baseplate had "up" printed on it, and that side went up. The adjustable component of the dial is on the top, the thermometer component is on the bottom, and the little mercury bulb is on the upper right, just as I've always seen on these dials. The furnace is still acting the same, so obviously my programmable thermostat wasn't the issue, so hopefully I can convince my landlord to at least hook that back up instead of this crappy manual one. Heck, I only put in the programmable one to try and have a warm house when I get up to shower in the morning without running the heat all darn night. Having a manual one will kill that plan!
