The Company's SAVC02 is a high-end ventilation control device designed to vent attics in the
winter using temperature and humidity sensors and in the summer using temperature.
temperature drops to 28ºF the first time, a winter condition is sensed and the control activates its
humidity sensor. The attic is then vented whenever relative humidity exceeds a preset (adjustable)
%Rh (factory set to 35% Rh). Between 28º F and 60º F (spring), the attic is vented constantly. As
an alternative, the SAVC02 can also be set to the manual-on position and the ventilator would then
simply vent constantly regardless of temperature or humidity. This could be useful in prolonged
extreme subzero weather conditions. When the attic reaches 60ºF, the SAVC02 stops ventilation.
Ventilation, then, only occurs when the attic temperature exceeds the 105ºF setting. The SAVC02
control provides for fully automated year-around ventilation.

A new solid state temperature and humidity
sensor comes with the SAVC02 and is placed at
the attic's peak. It simply plugs into the side of
the SAVC02. There are no complicated controls
to operate or settings to make. Simply plug the
control into a 115-vac source and plug the Ridge
Ventilator, Space heater or the combination unit
into the control. Everything is fully automatic!
115 vac @ 10 Amps Max current output
n Can be used with existing attic fans
n Temperature sensing -40º F to +150ºF
n Humidity sensing 0-50% Rh @ -40 to 185ºF
Other specs include the following: Winter vent condition is set at 28º F; Summer vent condition
is set at 105º F; Excess humidity vented @ 28º F and below when humidity exceeds 35% Rh;
Summer heat is vented above 105º F; Winter ventilation occurs from 28º F - 60º F if winter is set.

Do not mount the sensor in the air stream of the fan or blower you are connecting it to.

extend the output operating power options.

levels above 35%. During the winter below 28 degrees F, the control monitors Rh levels and
seeks to keep the attic at or below 35% Rh levels. The control therefore seeks to keep the
internal humidity down and the internal temperature of the attic close to the outside ambient
conditions. See above description of operation.
