If the water flow through the heat exchanger drops and the temperature differential is too high, the water heater will shut down until the
differential drops during this time the display shows the message DELTA DIRECT BLOCK. If this situation occurs more than four times, the
water heater will lock out and will display the message FLOWRETURN DT FAULT. Upon resetting the water heater, the output will be limited
