I have an older analog Lennox thermostat and am replacing with a Lux ATX500 thermostat. The Lennox thermostat connections do not match those on the Lux.
The Lennox is a 6 wire connection with terminals: F, V, R, X, Y, M

The Lux has terminals: G, Y, W, RH, RC

The Lux instructions are very general, can you help me reconcile these connections?

Thank you

This chart should help tell you what those Lennox terminals go to.

Post back if you have any lingering questions.

Need to know how to wire my LUK1500 programmable thermostat tomy forced air furnace.
