Belimo zone control 120 nc
« on: May 05, 2018, 12:09:37 PM »
Came across the above valve actuator, stuck open and abandon in the system, I am looking to wire in the system it is passing hot water in the heating coil as soon as you draw the water for domestic use,this is flow max boiler with small storage tank and air max system.
Any inputs how to wired system with above belimo actuators.The valve is hooked up on A terminal that powers up on call for heat.on off cycle it's bypassing hot water through the coil and not allowing to reach the desired temp.
