Quick question about Circulator wiring Weil Mcclain 97+
I have a condensing gas boiler that has control and end switches for DHW and 2 other heat zones. call for heat from low voltage terminal block inputs modulates boiler firing and circulation pumps for each of those zones with dedicated 120v terminals. DHW has priority settings from the boiler controller.
I am using only the DHW and one heating zone that is split into 4 zones controlled by taco 4 zone valve control.
The boiler is setup to output voltage for the heating circulator when a call from thermostats. But my taco also has 120v output for this pump? I feel like the solution to this is really simple but i cant find a definitive answer in my research.
I thought that in my case the circulator output was to supply voltage to the taco because in the manual it says as follows:
Use zone 2 output to:
a. provide 120v to system circulator(such as on a zone valve system with system circulator
b. provide 120v to a zone circulator
c. provide 120 v to a relay coil with relay contact used to enable/disable another device
i thought that option c was what i was looking at, but i cannot find a setting to change that makes the boiler treat that output as anything other than a pump.
Does anyone have experience with this, or know the solution?
Thank you in advance!
