thanks for the video, I have the L8148E, and I want to change my thermostat for the RTH6580WF. I only use the heat and my old thermostat works with two wires. where you should connect the wires for the other thermostat. Thanks

What would cause the sensor on a L7224 to fry. I have had four L7224U units in the last four year and it keeps coming up with ERR 1 Code and sometimes and ERR 6.

What a your recommendation on hot water temperature on a hydronic boiler for a two family house.I have no zone valve

Can the L7224U replace the L8148a1017 and be more reliable?
