Is anyone know how the fast stat works and its wiring info?I was told that its require when you have 2 wire thermostat that feeds to furnace .Any inputs?
If you have 2 wires for heating and want to add AC you would use the Fast-Stat 3000. See the attached wiring diagram. The existing 2 wires would be used to connect the Fast-Stat sender to the receivers purple and red wires. The sender and receiver would then have additional wires to connect to W, R, Y and G at the appliance and thermostat.
That will be really helpful.I was on service call and the fast stat was acting up.I think I will go with this info can troubleshoot it easily.the.
