The VT7600H PI thermostat family is designed for multi-stage control of heating/cooling equipment such as heat pumps and self-contained units. The product features an intuitive, menu-driven, back-lit LCD display which walks users through the programming steps, making the process extremely simple. All models contain two user-controlled digital inputs that monitor filter status, change the occupancy status, and/or provide general purpose service indication. Some models include up to three remote sensor inputs. All devices are available with Echelon, BACnet, or wireless adapters.
