WARNING! LIVE ELECTRICAL COMPONENTS!

During installation, testing, servicing and troubleshooting of this

product, it may be necessary to work with live electrical components.

Have a qualified licensed electrician or other individual who has been

properly trained in handling live electrical components perform these

tasks. Failure to follow all electrical safety precautions when exposed to

live electrical components could result in death or serious injury.

Meets cULus requirements without the need of an electrical ground

connection.

Provide overload protection and disconnect as required.

Actuators may also be powered by 24 VDC.

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.

30

Override control for Y2 only accepts 0 to 10 VDC override control.
