These are great 24V relays with internal 24V power supply. They can be used as a DPDT switch relay aor use one set of NO contacts for a circulator (and use the second switch for something else (an indicator light or something). I have one that has been in service for about a decade. It looks like the relay is a standard DPDT relay that could be replaced.

The Best
Worked perfectly for my application. No one had it locally in stock. Supply House deliverd sooner than a local national distributor could. Not to mention 20 % cheaper. The only time I purchase local is when I have too.

This unit is great for one zone
I was hoping to use it to control one zone AND provide 24 volts to empower a Tekmar 356. Pex was very helpful in obtaining Argo input who stated that the transformer was too "weak" to simultaneously empower the 356. Pex accepted a return without question and helped me find the correct unit
Q: looking for the relay it self do you carry them if so how much
