heating, cooling, heat pump and dual fuel systems. The
Comfort Control is easily configured for heat pump or cooling
only and gas or electric or dual fuel heat applications via the
user friendly Installer Setup menu. The Comfort Control
features include separate heating and cooling setpoints,
selectable auto or manual changeover, adjustable energy
saving mode, adjustable filter reminder, outdoor temperature
sensing, remote room sensing and remote humidistat input.
Setup selections and diagnostics are stored indefinitely in the
