   Best to ask here or ?   
      
   My gas furnace is a Holly.   
   It has an old mercury two wire thermostat.   
      
   I want to change the thermostat so that I can set the same two   
   temperature ranges, day / night, for every day.   
      
   I do not understand thermostats.   
      
   The local store does not know how to advise me.   
      
   Thermostat suggestions please and maybe a little tutorial.
