1.1 DESCRIPTION
Congratulations on the purchase of your ECS 4+
environmental control system. The ECS 4+ provides you
with full control over temperature, static pressure, air flow,
and heat resulting in a comfortable environment for your
livestock.
The ECS + product line offers a number of added features
over existing ECS controls such as:
•
Hi/Lo temperature indication
•
Automatic temperature reduction (ramping)
•
Adaptable variable speed outputs for a wide selection
of fan models.
•
Static pressure probe
Kits are available to upgrade existing control units.
The ECS 4+ provides microprocessor control over a four
stage output.
The first stage controls a variable speed fan which can
operate at a continuous low speed to ensure good quality
of air at all times. In addition, the first stage may be
programmed to cycle ON and OFF. When room
temperature rises above the main set point, the fan
accelerates to increase the airflow.
