The demand signal...
requires 24 volt input. The output is dry contact. If you're using a zone valve, you must supply the R leg thruput for the output side of the controller.
Boy, aint that edit feature somethin'...In your case, if you're using a Taco priority zone pump, the tekmars' output would be connected to terminals 1&2 on the Taco ZF pump.
Hope that answers your questions.
