P1 & P2 PRE-CYCLE FAN PROVER STATUS CHECK
The Pre-Cycle Prover Status Check is deactivated from the factory on the SS1 Series. Because of
the low set point of the SS1 Fan Prover (as low as .03" w.c.) cross winds may cause the Fan
Prover to close prior to a call for heat. Activating the Prover Status Check on the SS1 may cause
nuisance lockouts. Pre-Cycle
