SERIOUSLY, the only type of thermostat I recommend for anyone is the Honeywell types and not the cheaper models. You really do get what you pay for price wise with thermostats. Contractor grade are even better and have a 5 yr warranty but not available at Ctire or big box stores. Waste of time to buy cheap quality and priced tstats IMO and experience (you have been warned)
