The Comfort-Set 90 Series Model No. 1F93-380 is system selectable for single stage, multi-stage and heat pump applications. The design eliminates the need to stock multiple models of thermostats and sub-bases. Standard features include seven day independent programming and automatic heat/cool system changeover. A simple menu-driven programming sequence, backlit display and an illuminated keypad make it easy to adjust, even in low light conditions.
