Have just purchased a house, with what I am told, is a Honeywell. Thermostat, but no operating instructions. Display screen is 2 1/4 w, 7/8 h; up & dwn arrows to Rt. of screen; 4 buttons below scrn, marked:Time, Prog, Run, Hold. Last 2 are linked together, with Fltr under the link-line. Two more buttons to the rt side.1 mkd fan; on-auto. the other mkd system; cool / off / heat. Can any one help with a model # so I can order some inst? Tnks Hedley Hooper
