The Ranco ETC-112000-000 is a temperature controller commonly used for HVAC and refrigeration applications. To connect it to an indirect water heater, you can use it to control the temperature of the water in the indirect water heater's tank. Here's a general guide on how to do this: Please note: This is a general guide, and it's essential to follow the specific wiring instructions provided in the Ranco ETC-112000-000 user manual and the installation instructions for your indirect water heater. Materials and tools you'll need:

1. Ranco ETC-112000-000 temperature controller.
2. Indirect water heater.
3. Appropriate wiring and electrical supplies (cables, wire nuts, etc.).
4. Screwdrivers.
5. Wire strippers and crimping tools.
6. Electrical tape.
7. Safety equipment (gloves, goggles, etc.).

Steps to connect the Ranco ETC-112000-000 to an indirect water heater:

1. Read the Manuals: Before starting, thoroughly read the user manual of the Ranco ETC-112000-000 and the installation manual of your indirect water heater. This will ensure you understand the specific requirements and wiring diagrams for your equipment.
2. Turn Off Power: Ensure the power supply to the water heater and the Ranco controller is turned off at the breaker box to prevent electrical accidents.
3. Mount the Controller: Mount the Ranco ETC-112000-000 controller in a suitable location, typically on a nearby wall or control panel, within easy reach. Make sure it's securely fastened and level.
4. Wire Connections:
   • Connect the power supply wires (usually 120V or 240V AC) to the Ranco controller following the wiring diagram in the manual. Typically, you'll have two power wires: one for Line (L) and one for Neutral (N).
   • Connect the load wires from the Ranco controller to the electrical terminals on the indirect water heater that control the heating element(s). Refer to the water heater's manual for the correct terminals.
   • Make sure all wire connections are secure using appropriate connectors (wire nuts, crimps) and cover them with electrical tape to prevent any exposed wires.
5. Sensor Placement: Install the temperature sensor (usually included with the Ranco controller) into the water heater tank. Ensure the sensor is in contact with the water, as it will measure the water temperature.
6. Power On and Set Parameters: Restore power to the Ranco controller and the water heater. Configure the Ranco controller according to your desired temperature settings and control parameters. Refer to the Ranco manual for specific instructions on programming the controller.
7. Test and Monitor: Once everything is connected and set up, test the system to ensure it's functioning correctly. Monitor the water heater's temperature to make sure it maintains the desired level.
8. Final Check: Double-check all connections and ensure there are no loose wires or exposed connections. Secure the wiring neatly to prevent accidents or damage.

Check the breaker. Check the reset on the motor. Wiring connections. If you have power to the motor & motor doesn't work...you need new motor.

Normally you can just replace the motor with out changing the entire unit. A new gasket should come with the new motor.

Sounds as if it is siezing up, replace for new.

Replace it.

Last one I installed, I used a PIR sensor to control it, so that whenever someone walked towards the bathroom or kitchen, the pump will start up and run for 15 minutes. It really depends how often you use hot water - if only certain times of day, then it would be wasting power to run the pump, and heat loss from the pipes (unless very well insulated). If you have a regular pattern of use, then you could use a timer/programmer as you would on your normal hot water or heating. If your piping is plastic, then don't run pump continuously, as some plastic piping is not recommended for continuous circulation at normal hot water temperatures.

Sounds like the diverter valve is not working. In order to heat the hot water, it needs to direct the circulating water to the heat exchanger rather than the rads.

Look at it closely to make sure it is not a nipple threaded into the pump that can be removed and replaced. If it is indeed part of the pump you may be out of luck. You can take it to a competent welder that may be able to weld it but it may distort the pump body so it will not work. Good luck!
