Inquiry (采购产品): Home Thermostat Directions I live in a Navy Housing community in Groton, CT. We have an older "Columbus Electric model XL-411" thermostat in the house and we need to find directions on how to use this unit. I have searched the internet and have can't even find a reference to this unit. Please advise.
