Product Name(s): Smart II Plus DDC Controller; Smart II Plus VAV Controller; Smart II Plus Fan Coil Controller; Smart II Plus Heat Pump Controller; Smart II Plus MUX Controller
Product Description: 10 to 16-point (depending on model) application specific controllers.
Product Application(s): DDC controller: 2 different models with flexible loop configurations for zone and mechanical equipment control applications. VAV controller: 4 different models providing for pressure dependent or independent control of single or dual-duct VAV boxes including fan-powered boxes. Also provides for HW reheat valve modulation or 3-stage electric reheat. Fancoil controller: 3 different models for control of fancoils, induction units, unit ventilators, or single zone AHUs. Heat pump: 2 different models for control of single or multi-stage water source heat pumps, single or multi-stage air to air heat pumps. Both models provide for ventilation or mixed air control. Can also be used for packaged air-conditioners. MUX: 1 model provides for expansion of the Smart II network. Provides for remote interface/control of motor control centers, lighting panels, and mechanical equipment/AHU's.
