View Full Version : Replacing Janitrol HPT18-60 with LUX TX9100E Thermostat

Replacing Janitrol thermostat with LUX programmable Tstat, all wires lined up Y, G, R, O, C except W2 and E when switching from a Janitrol HPT18-60 to a LUX TX9100E.
The Janitrol had a W2 white wire and E brown wire, and the new only has W1 and W2. Should the old W2 white actually go to W1 (I assume it is the main heat pump) and then E to W2 for emergency electric heat?
