Lochinvar & A.O. Smith 100208495 Panel Mount or non-condensables in the system

or non-condensables in the system that drive up head pressure

Common issues include poor heat transfer at the hot junction

using a 40VA transformer like the R76734700 to replace a lower VA-rated part is acceptable as it provides more capacity for the 24V load

and this switch provides the necessary protection against restricted airflow or blower failure

Automatic Reset Function: Eliminates the need for manual intervention once the plenum temperature drops to the 125°F closing threshold
