NOTE: Set the ASHRAE parameters before using the controller in ASHRAE mode.
When you power the controller for the first time, you will be prompted to set the following ASHRAE
parameters:
• Measurement units selection (US or metric)
• No. of bedrooms (1, 2, ..., 6)
• Floor space (1000, 1100, ..., 5000 sq. ft. or 100, 110, ..., 500 m
2
)
• Fan capacity (30, 40, ..., 200 CFM or 15, 20, ..., 100 LPS)
If you do not touch any button, the controller goes to normal display after 60 seconds and you will be
prompted to set the ASHRAE parameters again the next time the controller is powered down and back
up. The ASHRAE parameters can also be accessed at any time.
NOTE: Refer to the ASHRAE parameter flowchart sheet on how to set the parameters.
After you have set the ASHRAE parameters, the controller will indicate whether you pass or fail to meet
ASHRAE 62.2 standards and will also indicate the percentage of time the fan will run based on your
ASHRAE settings. If this value exceeds 100%, the controller will indicate Fail; this usually means the fan
capacity is insufficient for your house.
