Control of Ventilation Fans
 With the Argus system, you can use a variety of control
strategies to operate ventilation fans. In climate control situations, the
operation of the ventilation fans is coordinated with your heating system to
maximize energy efficiency.
For multi-fan applications, the Argus system regulates the operation of fans
based on the current calculated ventilating requirement. Fans can be operated
individually or in groups to achieve varied ventilation rates. Each fan can be
controlled using a simple off/on strategy, or with pulse width modulation (PWM).
With PWM control, the control system regulates the on/off times as well as the
numbers of fans operating to precisely match the current cooling or
dehumidification requirements. This results in exceptional temperature control
precision. Fan operation can also be coordinated with evaporative cooling pad
systems.
For special applications, enhanced programs are available.
These powerful, highly flexible programs allow you to easily specify the rules
and conditions for fan operation that suit your requirements.
