A good replacement for a 194 that was not available
Used this control to replace a 194 with a #5 switch on a Cleaver Brooks boiler. The only issue I had was that the #5 switch had an additional terminal for closing the non spring return actuator on the globe feed valve. Has to disconnect the pump control switch to access the additional terminal on the bottom of the switch that is not landed on the wiring strip for the LWCO.
