without parts I cant see a way round it mate

maybe if you have an old solenoid valve and a relay

the bypass solenoid can be wired to the normally closed side of relay so when the liquid line solenoid drops out this kicks in

only other thing can think of is a shut off / isolation valve but that means you manually switching from cooling/heating mode

will message you on facebook if I can find one in my garage and see if I can post it to you
