Caution
The information described in this catalog is for the purpose of selecting the appropriate products.
Before actually using this product, be sure to read the instruction manual carefully to ensure proper
operation.
1. PID control functions built in as standard
• By controlling the cold/warm water temperature of the air
handling unit uniformly, the energy savings can be realized in
accordance with the reduced amount of pump flow that
accommodates changes in the room temperature.
• Till recently, a temperature controller has been required.
However, because PID control functions are built in as
inverter functions, the water temperature can be controlled
uniformly simply by installing a temperature sensor (4 to
20mA) at the pump outlet.
2. Greater energy saving effect obtainable combined
with automatic energy saving operation function
• Normally, the cold/warm water pump has the variable torque
characteristics. The axial force of the pump is directly
proportional to the rotating speed cubed. If the rotating
speed (amount of flow) drops to 80%, the axial force will be
approximately 50%. As a result, compared with the amount
of flow when the flow is restricted by the valve, significant
energy savings can be expected.
• Moreover, you can anticipate greater energy savings by
setting the automatic energy-saving operation function
(Function code: H10) to 1 (Active).
3. Unnecessary to resort to any special sound-
proofing measures; Fuji inverter drives a motor
with silent motor sound.
• We have succeeded in eliminating most of the unpleasant
motor sound that usually comes from the motor which is
driven by the inverter.
The sound levels are comparable to those of commercial
power sources.
