4. Route the wire cable into the timer through the
large opening in the base of the housing or
through PVC conduit (if installed). Strip insulation
back 3/8
″ (10mm) from all cable wires.
Note: The zone modules have quick-release wire
terminals. To attach wires, simply raise the lever,
insert the stripped wire, and press the lever down
to secure.
5. Secure the valve common wire to the terminal
labeled COM. Connect the individual zone valve
wires to the appropriate zone module terminals.
Connect the master valve wire (if applicable) to
the terminal labeled PUMP/MV.
Connecting a Pump Start Relay
Note: Connecting a master valve or pump start relay
is optional and may not be required for your sprinkler
system.
CAUTION: To prevent timer damage, do not
connect the timer directly to the pump starter.
A 24 VAC, 0.3A (max) relay must be used.
1. Route wire pair from the 24V relay into the timer.
2. Connect one wire to the terminal labeled COM.
Connect the remaining wire to the terminal
labeled PUMP/MV.
CAUTION:
To prevent pump damage due to
back pressure, remove all unused zone modules.
Connect a jumper wire from an unused zone
terminal to a terminal with a valve connected.
Connecting the Plug-in Transformer
CAUTION: Do not plug the transformer into an
electrical outlet until all of the wiring procedures
have been completed.
1. Route the cable from the transformer through the
small opening in the base of the housing.
2. Connect one cable wire (in either order) to each
terminal labeled 24 VAC.
Note: The display will begin flashing 12:00 am.
Press any button to halt flashing.
