A fan speed controller is provided as standard on full featured condensing units and can be installed also as an accessory in the

field  on  all  N  series  condensing  units  that  are  equipped  with  a  pressure  tap  (see  diagram  below)  for  easy  installation. The

Saginomiya pressure type controller (YORK P/N 025T20003-000) is recommended. Fan speed controllers should be added when

the units are installed where operation in cool mode is required during periods with low outdoor ambient temperatures. Complete

installation instructions are included with every fan speed controller kit ordered from the factory.
