Rain switch bypass
I have a Toro timer (Custom Command 18-station)with a Irritrol rain detector/switch. The system worked fine last year. This year, however, the system ignores the fact that the Irritrol transmitter/receiver are activated by rain. The owners manual that came with the Toro timer is useless. It does describe a "bypass" wire that the device is shipped with. The rain switch takes the place of this bypass wire. From reading the Toro owner's manual it appears that in the absence of a rain switch the bypass wire needs to be in place for it to work. Would I be correct in assuming that the rain switch functions like the bypass wire (under dry conditions)? That when it rains the switch opens-deactivating the circuit? If so my problem is the irritrol device and not my toro timer? Could this be verified by testing teh Irritrol sitch with an ohm meter?
