P1 & P2 PRE-CYCLE FAN PROVER STATUS CHECK
The Pre-Cycle Prover Status Check is deactivated from the factory on the SS1R. Because of the
low set point of the SS1R 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 SS1R may cause
nuisance lockouts.
