ADVANTAGES OF THE ECO

ENERGY SAVINGS

The Eco range provides considerable potential for
energy saving in the following areas:
• Air flow requirements are matched precisely to
demand.
• Optimum system regulation means less
energy/power is required.
• The requirement for changing clean air filters
is reduced.

CONTROL & REGULATION
The Eco range enables the following
improvements to system control and regulation.
• Finer control of system functions as the Eco
accurately follows set points.
• Closed loop process control using a standard
Proportional, Integral, Derivative (PID) control
loop function.
• Reduced overshoot of pre-set parameters,
provides optimised levels of comfort.
• Automatic compensation for system
fluctuations - partially blocked filters.

PID - INTERNAL

Closed loop process control using a standard
Proportional, Integral, Derivative (PID) control

NOISE

Noise reductions can be achieved by reduction in:
• Motor and fan rpm.
