RA890A Circulator Relay SPST

Is there any way to wire 2 RA89A Cir relays (they have no XX) to control the burner (gas) switch together? With out adding a separate relay on each control? If they are in series with the TT won't the current from the 2 separate transformers buck each other? Thanks for your input. Jake

Not sure if I read you.
Are you trying to energise 2 RA890 controls off 1 or 2 t-satats? If its off 2 stats, as long as the contacts are dry, its ok. If you are using T-87f or similar with heat anticipators, it is not recommended. Your 2 controllers together wired in parallel and phased properly will increase your va only. I guess I need more detailed info. you said XX is not on the controller. Is that both, just 1 etc... Be more descriptive if possible.
Peace
