Can the 72V speed control work in tandem with the 350/355 roof vent fan thermostat?
Can the 72V speed control be made to work in tandem with the 355BK fan thermostat? I would like to have the option to manually control the fan with the speed control as well as have it work automatically via the thermostat. Can this be done, and if so, how should it be wired and operated?
Thank you for your question on the model 72V solid state speed control. The 72V can be used with the 350 and 355 roof ventilators. For specific wiring information please contact our Technical Service Department at 800-637-1453.

Can the 72V due to it's heatsink size be used in a double gang box with a decora cover plate?
Viewing the Broan Spec Sheet on Wall Controls it appears due to the heat sink fins this unit will not fit completely inside a box to be used with a standard decora cover plate as other standard outlets or switches do at home. Re: I am attempting to install it similar to the way P/N 62V is visually shown on the same Spec Sheet.
Thank you for your question on the model 72V solid state speed control. The 72V is designed to fit into a single gang box. The only restrictions would be to use a box that is at least a 2-½” deep when using 14 gauge wire or at least a 2-¾” deep when using 12 gauge wire. Please contact the Technical Service Department at 800-637-1453 for further assistance.

Ceiling fan just started running at low speed no matter the setting
Attic fan started running slow, no matter the speed control setting.
I have had electric fans stop working, but I've never heard of one still working but only running slow
Thank you for your question on the Broan attic fan. You can check the voltage coming out of the switch to see if it is varying voltage to the motor. If you have questions please contact Technical Support directly at 800-637-1453.
