I'd like to know if it possible to install a 240 volt ST01 timer in the diagram below. The timer wiring is:
Black - Line
Blue - Load
Red - 3 way (not used)
Green - ground
This is where I'd like to install it - replacing the bypass switch. I'm unclear how to do the installation since it is 240v with 2 hots and no neutral. Do I have to make the connection through the contactor (which is already wired to the pressure tank switch) ? The bypass switch is used in the spring time to directly run the well pump continuously to fill the pond, bypassing the pressure tank and contactor. I want to be able to do the same with the timer (on continuous) but then also have the timer functions available in late spring time to only run at night. When there is no threat of freezing I will shut down the ST01 timer and run a hydrant with a mechanical timer and the pressure tank/switch.
