4. CHARACTERISTICS OF FAN
ȷCharacteristic FAN (1) shows air flow vs. External Static Pressure (E.S.P.) range where settings of E.S.P. are maximum E.S.P. (SW8-4 OFF
: 150Pa, SW8-4 ON : 200Pa) , rated E.S.P., and minimum E.S.P. (SW8-4 OFF : 80Pa, SW8-4 ON : 10Pa)
ȷCharacteristic FAN (2) shows air flow vs. E.S.P curve when set fan tap is set P-Hi with each setting of E.S.P . by remote control.
ȷExternal Static Pressure (E.S.P.) can be set by wired remote control.
ȷYou can set required E.S.P. by wired remote control which calculate it with the set air flow rate and pressure loss of the duct connected.
