Upgrading analog immersion circulator with 612

[sw2geeks]

Hi, I was wanting to upgrade and old analog immersion circulator with the 612 controller. It looks like it would be pretty straight forward, but now I am not for sure how I would hook up the relay for the heater if the power is not being powered through the 612.

The heater element on the circulator is controlled right now by a very simple pressure switch that has a single line coming in and out (pretty much like an on off switch). Can that switch be replaced with the SSR relay with the same wire hookup and be controlled by the 612?
If so, what would the wire sequence be.

Thanks for any info.

Hi. I for one need more info. What supplies the pressure to the pressure switch? A finger? Some mechanical apparatus? I obviously know nothing about analog circulators, so education is needed here. Then maybe a rec can be made.
