Hi. I decided today to replace the old mercury thermostat with a new digital one. I turned off the breaker, removed the the old one, labelled all the wires, and installed the new one. When I attemped to start the heat, nothing happened. After I rechecked my work, I re-installed the original one. Now that does not work either. Switching the fan to on and trying emergency heat does nothing as well. My heating system consists of an outside york heat pump, an inside york blower, and a hyrokinetic unit. The hydrokinetc unit appears to working fine, as the pipes are too hot to touch and it kicked on a little while ago. My assumption is something is wrong in the connection between the thermostat and the blower or some part failed. Can anyone provide any insight? Since its Saturday, I'm probably stuck until Monday. Hope it doesn't get too cold. My dad is gonna check it out tomorrow, but maybe I can get some ideas of where to look and avoid big repair costs. Thanks!
