Temp probe to trigger

Is it a smart idea to have a temp prove trigger the return pump (relay 8) to turn it off? My home stays a constant 70 degrees. Thus I will have a probe in the emergency overflow PVC and once it reaches 77.5 (tank temp) it will turn off the return pump.
If so, code please?

I use an ATO switch like this. It is a safety switch for a clogged return from a snail or debris problem. Depending on your pump, I don't know if the temp response would be fast enough. Otherwise it should work in principle.

I would set the off to 74.0 as the home never gets that hot

So...
if (ReefAngel.Params.Temp[T2_PROBE]()<740) ReefAngel.Relay.Off(Port8));
else
ReefAngel.Relay.On(Port8);
??

no, it is correct.
you just got some extra () in there
Code: Select all
if (ReefAngel.Params.Temp[T2_PROBE]<740)
ReefAngel.Relay.Off(Port8);
else
ReefAngel.Relay.On(Port8);

So if probe less than 74.0 relay 8 off. Else On
I need if probe reads greater than 74.0 relay 8 off. Else on

Hahahaha. I was confusing myself. Not your fault. Hopefully I'll never have to see this work anyway. It's for emergencies anyway
