When a pump start relay or a master valve is to be operated by the controller, a

compatible device must be used. The master valve must be equipped with a 24 V a.c.,

0.2 amps, 5VA solenoid. If using a pump relay, it should have a nominal coil voltage of 24

V a.c. at 0.25 amps maximum. The controller should not be installed within 5' (1.52m) of a

pump or pool equipment.

Step 1 - Route the relay or the master valve wires to the controller using the same

conduit opening used for the valves. See Figure 2 on page 5.

Step 2 - Connect one wire to “MV/PUMP” terminal and the other to “VC” terminal.

CAUTION: If you are using a pump start circuit, the fail-safe program will activate the

pump for each valve for 10 minutes on Program A. If all valves are not being used,

the pump will run against a “dead head” on each unused valve. This can damage the

pump. To avoid this, connect a jumper wire from the unused valve terminal to a valve

terminal that is in use.

Power Connection for Indoor Model

After you have installed the controller securely and made all necessary valve connections,

route the two leads from the plug-in transformer through the bottom conduit opening and

connect to the “24 VAC” terminals. Close the control module and plug the transformer into

a 120 V a.c., 60 Hz power source (230 or 240 V a.c., 50 Hz power source for

international models). The display should flash “12:00 PM”.

Power Connection for Outdoor Model

Outdoor controllers have a built-in transformer which must be connected directly to a

grounded, 120 V a.c. power source (230 or 240 V a.c., 50 Hz for international models).

Connecting the Power Supply

Pump Start Relay or Master Valve Connection

Warning: All electrical components must meet applicable national and local

electrical codes including installation by qualified personnel.

On outdoor models, these codes may require an external junction box mounted on

the transformer 1/2" NPT nipple and a means in the fixed wiring of disconnecting

AC power having a contact separation of at least 0.120" (3mm) in the line and

neutral poles.

Ensure the AC power source is OFF prior to connecting to the controller.

The wire used for connection to the controller must have insulation rated at 105° C

minimum.
