Resideo Honeywell ST9120U1011/U Universal Electronic Fan Timer Board
Resideo Honeywell ST9120U1011/U Universal Electronic Fan Timer Board
Combustion Blower and Circulating Fan in One
Replaces all others. The new universal platform that will not only integrate control of
all combustion blower and circulating fan operations in a gas warm air appliance but
also replace all other existing Resideo fan timer boards. It now has a replaceable fuse
and DIP switch with selectable heat and cool delay for added flexibility. This new fan
timer will also save you time and money with its diagnostic LED and continuous EAC
and HUM terminal connections. These new options and features make it the best fan
timer for your needs.
On the surface, the job of the ST9120U1011 is very simple: monitor temperature
demands and run the fan as needed, but the ST9120U1011 also handles all the little
complexities of the job. And best of all, it’s ready to work in just about every situation,
replacing more than 44 other models.
Smart Choice
The ST9120U1011 monitors the thermostat for heat, cool and fan demands, runs
the induced draft blower motor and runs the circulating fan (up to two speeds) as
needed. It also monitors limit switch strings and energizes ignition control. In short,
this one little unit packs a big punch, making it a smart choice for your applications
as well as your business.
Universal Compatibility
The ST9120U1011 will replace all existing Resideo ST9120's, ST9101's, ST9141's and ST9160's. Save room on your truck with a supply of ST9120U1011 timers and know you’re covered. You’ll save time by not having to search for the right model and you’ll enjoy a truck that’s easier to organize.
