DC LATCHING SOLENOID START-UP PROCEDURE:
Because some DC Latching solenoids will default to the latched (open) position
before installation, the valve will appear to be stuck open.
It is necessary to energize all zones to unlatch the coil and close the valve prior
to installation.
From the Manual Operation Screen, select each active station and run for 2 seconds
each. This should unlatch the coil and close the valve on each station, should the
plunger be latched magnetically prior to installation.
Resetting the security key: If you need to reset the security key (passcode set on
the device), disconnect the battery and make a short circuit on the battery connections
for 10 seconds, then reconnect the battery (see illustration below).
Launch the App and Add the device to your account by following steps 1-5.
Go to the Edit screen and type in a new security key.
09
Reconnect and
insert the battery.
Make contact on the battery
terminals for 10 seconds
with something metallic
— like a screwdriver.
