P1 & P2 PRE-CYCLE FAN PROVER STATUS CHECK
The Pre-Cycle Prover Status Check is deactivated from the factory on the SS1-R. Because of the
low set point of the SS1-R 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-R may cause
nuisance lockouts. Pre-Cycle
