Bob - question on blower motor

[DanEC]

Bob - I'm kind of confused on the blower motor. As it is furnished, I belive it is simply an off/on affair handled by a two-pole toggle switch. But, there are various references in the manual about a 2-speed and even 3-speed heater unit being furnished and some discussion about wiring in a separate switch to control the additional speeds.

I assume with just the off/on switch it will run on high in the on position. Typically heater motor lower speeds are operated by a resister or resister bank. There is a discussion about wiring in a separate 3 pole switch but I'm unclear on the wiring. Is the idea to disassemble the heater and splice a switch to the internal wiring for the motor? There is just a single wire coming out of the motor as delivered. Seems strange the motor and wiring internal to the unit would be set up for multiple speed operation but there isn't any plug and play capability on the outside of the unit. Is there a further discussion or description of this process somewhere?

Maybe I'm missing something all to obvious again.

Thanks

Dan
