Electronic Enthalpy, and Dierential Enthalpy Controls may not be
used in any climate zone for compliance with Section 140.4(e)1
unless approval for use is provided by the Energy Commission
Executive Director.
At altitudes substantially dierent than sea level, the Fixed
Enthalpy limit value shall be set to the enthalpy value at 75 °F
and 50% relative humidity. As an example, at approximately
6,000 foot elevation, the xed enthalpy limit is approximately
30.7 Btu/lb.
