Controller User Manual
In order to view or perform an I/O test, the eco-Air unit must be switched off (Figure 28). The test must first be enabled. After being
enabled, the digital outputs may be manually enabled or disabled. Note that enabling an output will cause the device attached to
the output to function.
When equipped with EC fan motors, it may be necessary to replace a fan motor. When an EC fan motor ships from the
manufacturer, it is programmed with a default Modbus address of 1. Once the replace fan configuration submenu is chosen,
navigate to the fan that needs to be replaced. Use the
UP
or
DOWN
buttons to navigate between the different fan addresses. Next,
set the current address to 1 and set change now to YES. After a several minutes, several messages will be displayed as described
in Table 27. Cycle power to both the EVAPCO Controller and the newly replaced EC fan motor. The new EC fan will now be
programmed to the proper Modbus address.
