I have an old thermostat that I tried to replace. I bought a
replacement from honeywell, but it's not working. Now my old one is
broken, I have no heating, and it is -2 Celcius outside...
I live in a condo and I know we have a heating/air conditioning unit
on the roof that cools down or heats up water that is then sent down a
pipe travelling through each condo's unit. The unit in my condo then
circulates the air. If anyone knows the official name for such a
system, that could probably help me ;)
I checked on the unit itself, and there are 5 wires plugged in, going
through a telephone-type cord. The screws are marked R, G, Y, W and X.
I tried connecting them to the new Honeywell CT3600 programmable
thermostat, but it doesn't seem to be working. There's a
three-position switch (heat, off, cool) that I put on heat, and the
fan switch (On, auto) that I put On. In that setting, the fan starts
blowing, but the air is at room temperature, and even after hours of
running it, the place is still cold. If I try to put the fan on Auto
mode, I can see the heating indicator come on on the thermostat and I
hear a 'click', but the fan doesn't start by itself.
I don't know if I have the wrong type of thermostat or what, but I've
tried two different models to no avail...
Does anybody know what should be done ?
