How to troubleshoot Watlow Controller no heat/cool action?
If your Watlow Controller isn't producing any heat or cool action, check these potential causes: * The output function might be set incorrectly; ensure it's set correctly. * The control mode might be set incorrectly; set it appropriately (Open vs Closed Loop). * The output could be wired incorrectly; correct the output wiring. * The load, power, or fuse might be open; correct the fault in the system. * The control set point might be incorrect; set the control set point in the appropriate control mode and check the source of the set point: remote, idle, profile, closed loop, open loop. * The controller model might be incorrect for the application; obtain the correct controller model for the application.
