-13 A spa pump control interface interposable between a two speed spa controller and a multi-speed axial flux spa pump including: a high speed power input receivable from the two speed 5 spa controller; a low speed power input receivable from the two speed spa controller; a heater power input receivable from a spa heater operatively associated with the spa; a high speed signal output operable for signalling the axial flux spa pump to operate at high speed; an intermediate speed signal output operable for 10 signalling the axial flux spa pump to operate at intermediate speed; a low speed signal output operable for signalling the axial flux spa pump to operate at low speed; switching means operatively interposed between the power inputs and the signal outputs for switching and operable to: switch on the signal to 15 the high speed signal output when power is received through the high power input; inlet one a selected one of the power outlets; or switch on the signal to the low speed signal output when power is received through the low speed input instead of the high power input; or switch on the signal to the intermediate speed signal 20 output instead of the low speed signal output when power is received through the heater power input. |
