When having your electrician install your 2012 Toronto Aurora hot tub, be sure that the appropriate action is taken for the white jumper wire running from pins J32 to J26. If you are using a single service install (service 1), the wire should NOT be removed from the pack. Otherwise if you are using dual service (service 2), leave the wire intact. Note that the “Dual Service Option” isn’t twin phase, but 2 x Single service.
If this isn’t setup correctly, your spa won’t heat up, and simply requires the removal of this wire or addition (depending on the install option) to fix this problem.
