tines for zone level humidity control, zone level demand
ventilation (ASHRAE 62) and automatic fan speed control
based on demand. System benefits include demand limiting
for maximum energy saving, and compatability with i-Vu
control system tenant billing for tracking tenants after
hours energy usage. Hardware features include on-board
hardware clock, remote occupancy input, and support for
space temperature thermistor sensor for stand alone
operation.
