Each item will be discussed in further detail later, however this section can be helpful in getting acquainted with the different options available. D – Control Dial Automatic – Normal dial position for all controller automatic and manual operations. Current Time/Day – Allows current day and clock time to be set.
MOUNTING THE INDOOR CONTROLLER TO WALL .......................................................... B NOTE: The indoor EC is not water or weather resistant, and must be installed indoors or in a protected area. A 1. Select a location as close as possible to a standard electrical outlet, one that is not controlled by a light switch. The location should be protected from moisture and direct sunlight. 2. Place the controller at eye level.
MOUNTING THE OUTDOOR CONTROLLER TO WALL ....................................................... NOTE: Outdoor model is water and weather resistant. Connecting the outdoor EC to the primary power should only be done by a licensed electrician following all local codes. Improper installation could result in shock or fire hazard. A B 1. Select a location that is conveniently close to a power supply. 2. Make sure to abide by all electrical and installation codes when attaching to an external wall. 3.
CONNECTING VALVES AND TRANSFORMER .................................................................... 1. Route control wires between valve location and controller. Typically it is recommended that at least 1 mm diameter conductor cable be used. This type of cable is insulated for burial and is color-coded to help keep track of your connections. 9.
CONNECTING THE BATTERY................................................................................................. Wire Clip Battery Compartment Connect a 9-volt alkaline battery (not included) to the battery wire clip located in the lower left-hand side of the controller. The battery will allow you to program the controller without AC power. However, the battery will not be able to activate any of the station valves. AC power must resume before watering will continue.
CONNECTING A PUMP START RELAY ................................................................................. NOTE: Complete this section only if you have a pump start relay installed. A pump start relay is a device that uses a signal from the controller to actuate a separate electrical circuit to energize a pump to provide water to your system. 1. Route a wire pair from the pump relay into the controller housing. 2.
CONNECTING A WEATHER SENSOR ................................................................................... A Hunter Mini-Clik ® rain sensor or other type of micro-switch weather sensor can be connected to the EC. The purpose of this sensor is to stop watering when weather conditions dictate. 1. Remove the jumper that is attached across the SEN terminals of the controller. Weather Sensor SEASONAL ADJUSTMENT WATER DAYS SEN AC 9V Battery C P 1 2 3 4 5 6 RST 2.
