Dry Bulb temperature change over

control - C7250A

FEATURES

• This unit mounted C7250A temperature sensor

includes solid state temperature sensors.

• Outputs a 20k NTC signal to the controller based upon

temperature. This enables economizer modes of

operation when outside air temperature is suitable for

free cooling.

• Temperature sensors are compatible with Honeywell

economizer systems.

• The economizer changeover temperature set point is

programmed via the economizer controller.

• Ambient temperature operating range from -40 to 150F.

• An outside air temperature sensor enables

economizing anytime the outside air temperature is

below a predetermined value.

• Unit mounted C7250A temperature sensor in outside

air and C7400S Sylkbus sensor in return air switches

the controllers to economizer mode of operation

anytime the outside temperature is less than the return

air temperature.

• UL recognized component (Guide info XAPX).

Guide Specifications:

1. Unit mounted C7250A temperature sensor including

solid state temperature sensors with electronics

which shall output a 20k NTC signal to the controller

based upon temperature to enable economizer

modes of operation when outside air temperature is

suitable for free cooling.

2. Temperature sensors are compatible with Honeywell

economizer systems wherein the economizer

changeover temperature set point resides via the pro-

grammed set point change over in the economizer

controller.

3. Ambient temperature operating range shall be

-40 to 150F.

4. An outside air temperature sensor shall enable econ-

omizing anytime the outside air temperature is below

a predetermined value.

5. Unit mounted C7250A temperature sensor in outside

air and C7400S Sylkbus sensor in return air shall

allow the economizer controllers to switch to an econ-

omizer mode of operation anytime the outside tem-

perature is less than the return air temperature.
