the furnace will short-cycle or refuse to ignite the burners at all

facilitating accurate ECM motor troubleshooting and performance validation

the valve modulates to allow more water flow through the condenser to increase heat rejection and bring the pressure back to the desired range

It automatically switches the thermostat's internal circuit to the correct mode (heating or cooling) based on whether the central chiller or boiler is active

Can this be used for valve actuation
