Old thermostat was a honeywell and the new is a honeywell RTH230B. Everything matches up for the wiring except that the old thermostat has a W1 and a W2. The new thermostat only has a W. Any insight to this would greatly be appreciated.
Thanks!

The old thermostat has a two-stage heating system. If you have only one "W" wire you would connect it to the "W" terminal on the new thermostat.
If you have two "W" (W1 & W2) wires then you need a different thermostat. The one with only a "W" terminal is a single-stage heating thermostat.
