Installation Instructions

The WeatherTRAK LC Central is intended for indoor and outdoor wall mounting on a vertical surface. The enclosure can also be mounted to a WeatherTRAK powder-coated steel or stainless steel pedestal.

Wall Mounting The controller can be mounted at a height between 42-54 inches above a finished surface and uses a center “keyhole” mounting method for the top mounting hole. Locate the position of the controller and mark the location of this upper mounting hole. Use an appropriately sized and type of drill bit depending on the material of the vertical surface. Use the plastic insert for masonry, stucco or drywall installations. Insert and tighten the mounting fastener until approximate 1/16” of the fastener thread length is left exposed. Hang the enclosure on this exposed fastener and then mark the 2 (qty) lower mounting holes per Figure 4. Once the remaining two mounting holes are drilled and fasteners installed, tighten the top fastener from the inside of the LC Central enclosure.

Connecting AC Power The WeatherTRAK LC Central utilizes a single phase, 2.0 amp transformer which can be accessed by removing the safety cover located behind the command module. It is recommended the command module is removed and carefully set aside to provide better access to this area inside of the enclosure. Three (3) wire nuts are included with the mounting fasteners to connect to a 3 conductor wire, 120 volt power source, see Figure 7. The primary side of the transformer has three color conductors noted as follows:

Green –earth ground,

Black – positive,

White – negative


LC Central AC Wiring Diagram Figure 7

Note: Prior to making AC wire connections confirm the circuit is de-energized to prevent injury from electric shock. This work should be performed by a licensed electrician meeting local and state electrical codes.

See the enclosed wiring diagram in Figure 7. Remove approximately ½” of wire insulation to expose the center conductor. Twist the appropriate colored wires and seal with a wire nut.

Note: The protective cover should be re-installed and held secure with the supplied fastener once these connections are made to prevent potential electric shock or confusion with similarly colored valve wire.

Once AC wire connections are made and the safety cover is re-installed, energize this electrical circuit. The LC Central’s screen will display a start-up message which takes about 20-30 seconds. About 30 seconds

Station Modularity

The WeatherTRAK LC Central has station modularity in 6-station increments. The base station count is 6 stations and can be increased utilizing a 6-station hardware key. Even though the station output board comes standard for 18 positions, the number of hardware keys determines the station count. Figure 8 identifies where these hardware keys are located.

6-station Keys

Figure 8

The station keys are “hot-swappable” and can be added while the controller is powered. Thirty seconds after the station key is inserted properly a light blue LED will illuminate above the terminal strip. Remember to go to the SETUP menu and increase the “Max Active Stations’ as part of this overall task.


Optional Flow Sensor

The WeatherTRAK LC Central has flow sensing compatibility when installed with a Flow Hardware key (see Figure 9). This key must be inserted to enable this particular feature.

Select a Program: Assign the station to a program that has a start time and water day mode. Use Water Window: If this station can irrigate outside of the water window, select “No”. Usable Rainfall: If a station is under a roof, heavy tree canopy or semi-porous roof, select either “None” or a percent of rainfall that is actually used. When “None” is selected, the specific station will water during Rain Pause. Sprinkler Type: Select 1 of 13 industry-recognized sprinkler types. When a sprinkler type is selected, a default precipitation rate and sprinkler


efficiency value is automatically assigned. Both values can be changed in the next two screens if different than the displayed default rates. Precipitation Rate: Is how much is applied in Inches per Hour. Changing the precip rate will change run times. Lower Precip rates = high run times, Higher Precip rates = lower run times. Sprinkler Efficiency: Every sprinkler applies water with a specific efficiency based on its design and performance and spacing. If head or row spacing is stretched, efficiency is less. (Higher = less water; Lower = more water). Soil Type: Select 1 of 5 soil types determined by the USDA. Plant Type: Select 1 of 17 plant types that best represents the valve zone being irrigated. Root Depth: Set root depth (Shallow roots = more frequent watering; deep roots = less frequent watering.) Sun Exposure: Select 1 of 4 levels of sun exposure of the valve zone being irrigated. Slope: Select 1 of 5 slope gradients. The steeper the slope the higher number of cycles will be applied. Sprinkler Location on Slope: Select 1 of 5 choices identifying sprinkler locations on a slope. Next Station: Press -> to go to the next station or use Use COPY to duplicate settings to like stations. User With ET Set run times, number of cycles and the soaks between cycles. It then automatically increases or decreases runtime based on the daily weather information defined as ET. Select Station: Locate the station to be programmed. Select Station Mode: Select User w/ ET Select a Program: Assign station to a program (with a start time, water window and water day mode). Use Water Window: If this station can irrigate outside of the water window, select “No”. Usable Rainfall: If a station is under a roof, heavy tree canopy or semi-porous roof, select either “None” or a percent of rainfall that is actually used. When “None” is selected, the specific station will water during Rain Pause. Set Runtime: Set a desired run time.


Set Number of Cycles and the Soak Time: Select from 1-20 cycles and Soak times from 0 to 480 minutes in 10 minute increments. Reference ET: Set a reference ET that is appropriate for the schedule just set. The number you see in parenthesis is ET for the past week and is the value to enter as Part 1 and 2. Alternately, you can set the program you would run in July and use a weekly reference ET that is normal for your area in July. Other Stations: Repeat these steps for other stations assigned to this station mode. Programming for New Landscapes User No ET User no ET is commonly used for plant establishment periods when overwatering is required to establish new roots. Run times, cycle and soak periods are all user defined in this station mode. User No ET sets up the same as User With ET except there is no reference ET. Activation is not required for User No ET. Copy This function lets you quickly copy all station settings from any particular station to any other station or to all stations. Press COPY main menu. Use the -> to select the station to copy from.
