All Parameters with formula above need to be

converted  for Celsius applications.

If current SPL is set for 20 degrees F the formula is (X-32) / 1.8

LAE Controller Parameter Settings

Resistance Readings 

for LAE Probes

for Celsius

(20-32) / 1.8 = -6.7 Celsius

We want to make it very clear that all parameter set points on the LAE controller have been set at the factory to 

optimize performance and adjusting any of these parameters in the field will affect the cabinet’s performance 

and could void the Warranty.
