Caution: If Equipment Contactor Coil
Current Draw Is More Than 2 Amps And/Or
Does Not Use A 24VAC Coil, A Pilot Duty
Relay That Has A Current Draw Of Less
Than 2 Amps @ 24VAC Must Be Used To
Energize The Equipment Contactor. A
Separate Transformer Rated For The Total
Pilot Relay Current Draw Must Always Be
Used To Power The Circuit.
