HVAC BUILDING SERVICES
– Maximum Fan Efficiency
– Accurate speed control of fans and pumps provides the most energy efficient control method
– Energy optimization function minimizes energy usage in real time under partial load conditions
– Sleep & wake functions ensure operation only when required
– Advanced on-board features remove the need for peripheral equipment
– Intelligent maintenance interval timing allows programmable maintenance reminders, avoiding costly downtime
– Automatic load monitoring provides an early warning of potential faults, such as belt failures or blocked filters
– Building Safety Systems: Stairwell Pressurization, Fume Extraction, Fire Override
– Fire override: Mode ignores signals and alarms, keeping the drive operating for as long as possible
– Energy Efficient Air Handling: Can vary the output of air conditioning system to meet the varying demands throughout the day, maximum occupancy and peak outside ambient
– Belt Break Detection: Provide immediate warning of broken belt between motor and fan
PUMP CONTROL
– Maximum Pumping Efficiency
– OPTIFLOW technology allows simple operation of multiple pump sets without the need for a PLC
– Pump blockage detection and cleaning dramatically reduces pump maintenance requirements
– Built-in PLC function
– Dry Run Protection: Drive can evaluate pump’s speed/power and shut it off or warn when the pump starts to run dry
– Motor Preheat Function: insures moisture does not collect on the motor in periods of inactivity and prior to motor start up
– Pump Stir Cycle: Triggered by a settable period of inactivity, a configurable cleaning cycle can be run to clear sediment
– Consistent Flow: Pump operating curve detection automatically detects and monitors normal pump behavior and is able to react when pumping conditions change
– Pump Prime with Burst Pipe Detection: helps to prevent the effects of water hammering
– Advanced sleep & wake functions provide maximum energy savings by switching off the pump when not required
– Any pump can be switched to Hand operation a the touch of a button, and will automatically rejoin the network when switched back to Auto
– For waste water applications, each pump can be set for blockage/ragging detection and activate an automatic de-ragging/pump cleaning cycle
