TACO SR503 Red Zone Light Constantly Switching ON/OFF

I have very little knowledge of the technical side... so as the title explains, I am noticing that my TACO SR503 Switching Relay constantly flickers the RED Light. My guess would be that it's due to a lack of electrical current maybe? it switches ON for 2 seconds, and powers the Circulatory Pump for a few seconds, then turns OFF... and the whole process repeats. Any help would be appreciated, Thank You!

    Please call into Taco Tech Support @ 401-942-8000 Mon-Fri 8AM-5PM EST. If you can be in front of the control and if you have a multi meter that would help as well if we need you to take a voltage reading. It could be as simple as a loose wire connection or if you have some type of power robbing t-stat you might just need a resistor. Also, does your SR control have a metal or plastic cover? That will let us know what generation control you have.

    Especially where to connect the com wire, most miss the small green terminal on the left one side 24vac and other side com.
