I have a 3 wire (power open/power close) zone valve I'm looking to control with 2 SR501's. Basically I want the valve to open when either one of the SR501's are tripped. I would also need to account for both being tripped at the same time. Is this possible? I have a spare SR501 to work with....

Thanks in advance, Jon
