Error 1135

At the system level of the building tree, in the residential tab, you have input a Whole House (the CEC uses the term Ventilation Cooling), the CFM rate for this fan exceeds a simulation limit of 3.5 cfm/sqft, which is an internal CBECC limit.  You must lower this airflow rate to simulate this home.  A typical value would be in the range of 1.0 – 2.0 cfm/sqft.
