I have installed a deep well at a pond on my property. The well will supply supplemental water to the pond via a hydrant, and it will also service a geothermal water-water heat pump 300ft away at my home. I need to be able to (continuous) run the well independent of the heat pump (cannot run hydrant/heat pump at the same time), so the plan is to turn off the geo heat pump and only run the hydrant water to the pond when needed. Plan is to install a contactor in the well pump's control box connected to a on/off switch for the hydrant; the heat pump control panel will also be connected to the same contactor to turn on the well pump when it calls for water (hydrant switch OFF). Everything is 240 volt. I have attached a rough drawing of the configuration along with a pic of the contactor. All of the necessary wiring is in place, I just need help on all the connections.
