• If the pump receives a signal to operate and after repeated attempts cannot turn
on due to the float switch not sensing adequate water, the EcoFlex™ Controls will
indicate a fault (optional alarm). See the Troubleshooting Guide on page 44 for
suggestions on how to address this.
EcoFlex™ Controls
BAC’s exclusive EcoFlex™ Controls allow for the TrilliumSeries™ Adiabatic Product to
operate in the mode of operation specific for your job conditions without you having to
think about it. Each unit is shipped from the factory with your specific climate conditions
and preferences in mind.
Modes of Operation Optimization
There are three different ways to optimize unit operation. The unit’s mode is located at the
default controls menu. Once the menu is shown, press enter and select the desired mode
of operation.
1. Standard Logic (Default): The controller will start the Pre-Cooler Mode at a preset
outside air temperature to increase the unit’s capacity and efficiency. This is the
default mode.
2. Water Saver Logic: The controller will optimize the unit’s efficiency and only use
water when the conditions require the extra cooling capacity. Pre-Cooler Mode will be
initiated only when the outside air temperature is above the switch point and the fans
are running at 90% or above for over 60 seconds. This mode will recheck conditions
every two hours.
3. Energy Saver Logic: The controller will optimize its sequence so that the least
amount of energy is consumed to meet the present load of the unit. If the outside air
temperature is 10°F (5.6°C) below the switch point and the fan speed is above 35%,
Pre-Cooler Mode will be initiated.
There are also additional settings and options to optimize operation:
