The 510 model water heater can be used to con-

trol a recirculation pump. Proper pump control

helps to preserve the life of the system and saves

energy.

The water heater pump control port is a normally-

open dry contact, and therefore needs additional

components to properly control a recirculation

pump, such as a relay. To control a recirculation

pump, connect the pump to a relay, and connect

the relay to the Pump connector in the water

heater as shown in the right diagram.

Easy-Link System, connect the pump ONLY to the

PARENT unit.) The pump must be connected using

suitable relays as shown in the right diagram.

Please make sure that the relays are properly

rated for the recirculation pump.

Using the water heater's internal thermistors as a

temperature control, the recirculation pump will

only turn on when recirculation is needed.

In an Easy-Link System, the pump must be connected to the Pump connector in the

NOTICE

PARENT unit using a suitable relay. If the pump is connected to any of the CHILD units,

the pump will not work.
