4.0 OPERATION If your enclosure has a thermostatically controlled blower, the thermostat is set to turn the fan on between 77° and 93°F (25° and 34°C) and to turn the fan off be- tween 62° and 78°F (17° and 26°C). If your enclosure has thermostatically controlled heaters or defroster, the thermo- stat is set to turn them on between 42° and 58°F (6° and 14°C) and to turn them off between 72° and 88°F (22° and 31°C). 11
