I just installed a new Multiwave (MW) to my old 60A power panel that had a 220V mechanical timer. On the timer connections for both load 1 and 2, they wired the hots from both the pump and heater under one screw. see attached pic. The black wires on load 1 for pump and heater, and the red wires for load2. I don't think this the the best way to wire. Would a pigtail been more appropriate with the single pigtail under each screw. Anyway I installed the MW last night and plan on the wiring today. Should I take both black hots and wire nut a pigtail to Load1 (Screw 3). and do the same with Load 2 (Load 2 doesn't have a screw, so wired direct to the CB). The other pic is the MW panel for wiring . So run hot from the CB to screw 2. Pigtail the 2 black wire from pump and heater to #3 (The switch). Take other hot from the 2 pole CB and run to screw 1. ( Screw 1 and 2 are the 2 line in for a 220). since no were to attach the load 2 wire from the pump and heater, do another pigtail to screw 1 to include the line 2 hot from CB and the load 2 from the pump and heater. They show a diagram on wire the 220 pool pump. I guess I would be adding the heater to those same connections. The diagram should show a power to screw 1 and power the pump. I know this is probably confusing. Picture2.jpg is my atttempt to show the wiring. Thanks for any help. BTW the connection for the heater is just power. screw 8/9 is for a fireman's switch
