Indoor Model: After you have completed all valve connections
and have a stable controller installation, route the two leads from your
transformer through the bottom hole and connect to the 24 VAC INPUT terminals,
then snap the control module closed. Plug the transformer into a standard 120
volt outlet. A flashing "12:00 PM" should show on the display.
Outdoor Model: Outdoor controllers have a built-in transformer which
must be connected directly to a grounded, 3-wire, 120 VAC power source. This
connection should be made by a licensed electrical contractor in accordance with
all requirements of the National Electrical Code and applicable state and local
codes. NOTE: Local building and electrical codes usually require that
approved electrical conduit and fittings be used to connect exterior, wall-mounted
equipment to 120 VAC power. CAUTION: DO NOT connect the contrller to one
phase of a 3-phase power system used by a pump or other electrical equipment.
To connect to an outdoor model controller, complete the following:
1. Turn of installation site power at the associated circuit breaker.
2. Verify that power has been turned off at the installation site by using an
appropriate AC voltage meter.
3. Install the conduit and associated fittings.
4. Connect power and ground wires per electrical codes.
5. Turn power on.
6. Check controller operation. If the controller is not operating, unplug
the transformer and check for shorts.
