BRS dosing pump

[nevets9333]

Hello,

I bought 2 BRS dosing pumps for Calcium and Alkalinity. On the BRS website it says to connect the pumps to a mechanical relay outlet not a TRIAC outlet. I have a relay and an expansion relay. What outlets can I connect these pumps to?

Thank you,
Steven

Any. They are all relays
