The Dream Aire 5000 ventilation system offers a combination of air-purification and bacteria-killing capability through the use of an electrostatic precipitation process (ESP) with a cleansing efficiency of 95 percent. The unit also serves as an energy- and heat-recovery system constantly moving air in and out of the classroom or office, with a heat exchange rate of 75 percent. The energy of exhausted air is retained in the unit's exchanger while fresh air is treated to ensure a consistent temperature. A thermostat inside of the unit recognizes the temperature of incoming fresh air, heating the air when its temperature is lower than 55°F or 65°F, depending on a pre-set temperature preference.

For light-commercial applications, Zone Control Panels can be configured to operate pumps or zone valves for up to five hydronic heating zones. Two panels can be daisy chained for control of up to 10 zones. The panels can be configured to give priority to domestic hot water so that it is available under all load conditions, including a single “hard-to-heat” zone.

The BAS Remote was developed as a BACnet/Internet Protocol (IP) remote input/output device that could connect to an IP Ethernet infrastructure. With a Modbus serial bus interface, the remote routed Modbus transmission-control-protocol messages to attached Modbus serial slaves. With firmware Version 3.0, these same Modbus slaves can be mapped as BACnet objects. The remote allows users of controls, such as those used with boilers and lighting, to convert Modbus variables to BACnet objects for installations as well as systems that require BACnet.

For light-commercial hydronic applications, Alpha 115-v circulators feature a permanent-magnet motor design that can cut power consumption by 50 percent or more. The circulators are equipped with the Grundfos AutoAdapt function, which automatically modulates circulator performance to match changing system demand. An electronically controlled motor features a magnetized rotor, which avoids motor-slippage problems.

The HydroZone hydronic-tank controller eliminates the need for external control devices when used in conjunction with the GeoTank large flow center. A sensor that is built into geothermal storage tanks enables the module to control water temperature using one of three strategies: outdoor reset (heating only), tank control (manual), or tank control (auto changeover). With menu-driven software and adjustable set points and deadbands, the unit can control up to four compressor stages. The fourth stage is configurable as auxiliary heat for the hydronic tank.
