Ok, running a Florida Heat pump AC in the house. It is a Geo-thermal open loop water cooled. I need to to find a 24 volt source inside the unit to hook up a valve and solenoid to feed the sprinklers when it turns on. It will close the sprinklers when off with thermostat as pressure switch works to turn off well. Could I hook into the capcitor? I am using the well for water to the house too. Simple right. Thanks in advance.
