As the room temperature deviates from 72ºF it can modify the discharge temperatures up to as high as 84ºF

and as low as 56ºF.

55ºF 72°F Pos 3 = + 14 69°F 41°F

As the room temperature deviates from 72°F it can modify the discharge temperature up to as high as 69°F

and as low as 41°F. Note you cannot reach a 72° room temperature. Also note that the internal design of

the

G-TRAC will resist dropping the discharge temperature below 52°F.

Ratio (pot 2)

Room Call Max Room Call Min

63ºF 72°F Pos 4 + 18 81°F 45°F

This will allow discharge temperature as high as 81°F. If the room set point were turned up to 76°F we

would reset discharge to 81°F until the space temperature was raised to about 76°F. Also note that the

internal design of the

G-TRAC will resist dropping the discharge temperature below 52°F.

NOTE: When dealing with systems that are equipped with room reset controls be aware

that any room sensor must be located in an area where it is sensing a true average

space temperature. A room reset that is located in a hot or cool area that does not

represent the room temperature will create room comfort problems. Also do not

locate the reset sensor in an area that is affected by discharge air from any duct or

other device. The G-TRAC terminals "RR and +" need to be jumped when when the

room reset is used. Note that on some wiring diagrams this may be jumped during

one mode and inactive in another.
