need to add a defrost on walk in cooler. dont have heater or hot gas valve, so its "compressor shutoff" type of defrost. I've got 208v power, so two hot legs, no neutral, and a ground.
as wired above, setup won't work. compressor doesn't kick on no matter how I set the timer. I assume this is because one leg is normally open for some reason on this unit. so I rewired it. black hot leg goes into spot of L1, and I took the red leg and just connected it directly to compressor leads. now it works on timer.
so- is that normal? for the timer/switch to only switch one leg off and on? Id assume it would switch both, but it won't work for me with both hot legs into the timer/switch. any issues with leaving one hot leg going to compressor at all times? seems odd to me. dont wanna cause issues for the compressor.
it seems there should be two normally closed legs in the timer. maybe I bought the wrong type of timer? but the manual says it works for 208-240v with timer on and timer off, compressor shutoff.
