This category offers a range of Electronic controls for the Hurricane 1100, 2100 & 3100 Heat Cool & Defrost Systems. The controls are also offered as an upgrade to our electronic units at a reduced cost when purchased with an inside or complete A/C system. If you would like to update an older Hurricane 1000, 2000, 3000 cable operated unit to an electronic slide control you can purchase a slide control package and a new standard or 90 degree defrost plenum.
