Help with Liquid Shutoffs

[Rotintin]

I'm trying to use a Thermo sensor to send coolant to 1 of two shutoffs. If below -252, one opens to warm the fluid. If above the temp, the other shutoff opens toward the aquatuner. It works most of the time, but occasionally a packet slips through and damages the pipe. Is there a way to build this without that happening? Or is this a lag thing?

Ignore the buffer gates. Also note that I've tried putting the sensor 1 box lower. Any advice would be appreciated.

Have the pipe sensor on the piece of pipe directly before the shutoff, or factor in the delay with logic.

I had the sensor right before initially, it was still faulty. Maybe i'll try a 0.1 second filter or something.

 A few tips for making this work properly.

1. Make sure you can ALWAYS supply moving liquid, ie, can you ensure that your pipes NEVER get backed up.  Use a pressure relief bridge somewhere on your piping, probably after the aquatuner.

2. Have the Thermo sensor IMMEDIATELY before the shut-off valve.

Assuming these two factors are accounted for, the thermo sensor can be wired directly to your valve and you should have no problems with it.
