CONTROL TESTING
1.
Note the ambient temperature at the point of the SST–3 temperature
probe.
2.
With unit power on, using the Down control button on the face of the unit,
enter a set point lower than the current ambient temperature. The green
SUPPLY LED light should be lit solid, but no other LED indicator lights
should be lit.
3.
Now, press the GFEP Test/Reset button on the unit face plate. The red
GFEP LED light should flash, indicating a self-test of the GFEP circuitry,
during which time you should also hear some clicking sounds from the
relays inside the unit. The red GFEP LED indicator light should go out
once the GFEP self-test is complete.
4.
Using the Up control button on the face of the unit, increase the set point
to be higher than the current ambient temperature at the point of the
temperature probe. The HEAT LED indicator light should now come on.
5.
At the conclusion of this test, set the adjustable temperature setting to the
desired operational level by using the Down or Up control buttons on the
front of the unit. If the set point is above the ambient temperature, the
HEAT LED will come on until that temperature is reached, after which,
only the green SUPPLY LED should be on. The test is now complete.
