Temecula, CA, June 09, 2013 --(PR.com
)-- Invisco Whole House Fan Company has just announced the world's first automatic speed control for the company's wide range of systems. The patent pending and trademarked SmartSpeed (tm) control uses the temperature of the home's interior to determine the amount of air that needs to be moved in order to cool the home in the least amount of time using the least amount of power.
All of Invisco's systems have infinitely variable speed motors. The two smallest units, the IN3620 (3620 CFM)and IN4750 (4750 CFM), are direct drive blades using PSC motors that work with variac speed controls.
The larger systems, the IN5600 (5600 CFM), IN6000 (8400 CFM), IN10600 (12,200 CFM), IN12600 (14,000 CFM), and the IN14500 (16,000 CFM) are all very quiet belt driven blades using EC (electronically commutated) motors. (Some Invisco systems have been upgraded to increase their CFM output since the part numbers were assigned. The part numbers remain because they are listed with the state of California's Energy Commission, Southern California Edison's list of suppliers, and the county of Riverside's HERO program).
All of the Invisco whole house fans can be controlled with the new computerized building control systems that use a 0 to 10 VDC signal to control speed.
The SmartSpeed(tm) controller has two modes of operation. There is a knob on the front that looks just like a light dimmer control. This knob can be used for either of two modes.
The first mode is "Auto". In this mode the control senses the temperature of the room or hallway in which it is mounted. When you turn on power (using any method including smart phone remote control) the control will start the motor up at the correct speed determined by the temperature. At 85 degrees or more it starts at high speed. As the temperature drops below 85 the speed is reduced (and the power in watts is also reduced) automatically until the temperature reaches the low point you set with the knob. At that temperature the motor is off. That low shutoff temperature can be any temperature from 75 down to 60 or, with the low temperature option, down to 40.
The second mode is "Manual". In this mode the control changes the knob to a speed controller. As you rotate it clockwise the speed of the motor increases from zero to full speed and will stay at your selected speed until you change it or turn off power. This is useful for pulling air out even when your home is cool in case you burn something in the kitchen or have another reason to move air from your rooms.
