Notes:
1 - Place switch to 208V position to operate unit at 208V.
2 - Connection of remote unit that does not have a loop pump for slave operation
3 - 24V Accessory relay (see SW2 - 3 for description of operation)
4 - The blk/wh and gray/wh wires are removed when Aux Heat is installed
6 - DHW pump only in models with hot water generation option.
