As the room requires more or less heat, the modulating room thermostat increases or decreases the calculated

discharge air set point

NOTE: If the room temperature is calling for a temperature adjustment, the “calculated” discharge temperature

set point will vary from the setting of “master” set-point.

• The room-reset feature is activated by dipswitch A-3.

• Room sensor calibration pot is labelled “ROOM CAL”.

• Reset ratio pot adjusts the reset authority (bandwidth) between 20°F and 56°F.

• Room reset band is ±3°F (fixed), to fully activate reset.

The “room reset band” means any room temperature error will begin to reset the discharge air calculation set

point, with the maximum amount of discharge reset achieved when the room reaches 3°F. The actual amount

reset (in degrees) varies as per both the setting of pot 5 and the discharge set point. The calculated discharge air

set point (dial setting + reset) is limited between 48°F and 120ºF.

To determine the amount of reset available use the following chart (See page 16).

EXAMPLE: G-TRAC2 set point 70°F

Reset Ratio Pot set at 3 (total reset 29°: +18 is upper reset limit, -11 is lower reset limit)

Room thermostat set at 72°F

Discharge set point is 65°

• If actual room temperature sensor is at 72ºF (satisfied), there is no reset. The unit discharges at 70ºF.
