Adjustable Thermostats for Solar- Powered Attic Ventilators

The Adjustable Thermostat (XXSOLRSTAT) for use with the above Models of
Solar-Powered Attic Ventilators is designed to turn the fan on and o
automatically.

THERMOSTAT SETTING

The thermostat setting governs the “fan o” temperature, i.e., the
temperature at which the fan turns OFF. When the temperature rises 15°
above the “fan o” temperature, the fan turns ON. As the temperature in
the attic is reduced, the fan turns o when the temperature in the attic
reaches the “fan o” thermostat setting.

The adjustable thermostat is pre-set at the factory at 90°. This setting is
user-adjustable. The setting that is best for your attic varies by
geographical location.

A setting that is too low will cause the fan to run constantly; a setting that is
too high will cause the attic to be over-heated since the fan will not turn on
until the temperature rises 15° above the “fan o” thermostat setting.

INSTALLATION

The thermostat should be installed in such a way that the thermostat
sensor, which is on the back of the control box, is not blocked. Usually, it is
best to choose a location where the control box can be suspended from
one of the rafters.
