I was wondering if someone can tell me how to wire a digital luxpro thermostat made by LUXPRO? We only have 4 wires coming from the wall white, green, red and blue.:o

Can you tell me how to bake a cake? Notice I didn't say what kind of cake.

What model stat? Lux Products - LuxPRO Series Programmable Thermostats (http://www.luxproproducts.com/program.html)

Go to the sticky at https://www.askmehelpdesk.com/heating-air-conditioning/heating-cooling-maintenance-repair-troubleshooting-frequently-asked-questions-58313.html Most heating systems and thermostats use the same red, green, white, and yellow wires. It explains that sometime a blue wire is used in place of a yellow for the A/C coil. Verify yours does before connecting the blue to the Y terminal.
