Actuators: LF24-ECON-R03 US LF24-ECON-R10 US AF24-ECON-R03 US
Actuators with plenum rated cable do not have numbers on
wires; use color codes instead. Actuators with appliance
cables are numbered.

Equipment damage!
Actuators may be connected in parallel. Power consumption
and input impedance must be observed.

CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury. It may also be used to
alert against unsafe practices.
Warnings and Cautions appear at appropriate sections throughout
this manual. Read these carefully.

INSTALLATION NOTES
26
Min-position is adjustable from 0 to 100% with a
potentiometer on the actuator cover.
27
A relay or switch can spring return the actuator when the
RTU fan de-energizes, or if low ambient temperature is sensed.
28
A standard relay can be used to close the sensor circuit to
engage economizer mode, e.g. outside air changeover device
like a dry bulb or enthalpy limit switch. Honeywell logic
module W7459A and enthalpy sensor C7400 also provide
terminals for this switching.
29
A remote CO2 sensor or DDC controller can change the
standard relay opening or closing the sensor circuit. This
device can be a relay or a dry bulb/enthalpy limit switch.
