The ST9120U universal fan timer will replace all other existing Honeywell fan timer boards. One control replaces all ST9101, ST91200A, C and G series Honeywell boards. This universal fan timer board has a replaceable fuse, DIP switch with selectable heat and cool delay, diagnostic LED and continuous EAC and HUM terminal connections. The ST9120U monitors the thermostat call for heat, cool, and fan demand, runs the induced draft blower motor, and runs the space circulating fan (up to 2 speeds) as needed. It also monitors limit switch strings, and energizes ignition control.

Specs: Power voltage: 24 VAC. Combustion blower: 1.5 amp full load,

10 amp locked rotor @ 120 vac.

Circulating fan: 15 amp full load, 30 amp locked rotor @ 120 vac. EAC and HUM: 0.8 amp combined @ 120 vac.

On/off delay settings:

Heating on delay: 30 or 60 seconds, field selectable. Heating off delay: 60, 120, 150, 180 seconds, field selectable. Cooling on delay: 4 or 30 seconds, field selectable. Cooling off delay: 30 or 60 seconds, field selectable.
