Thank you for purchasing the LAWN MASTER from Hardie Irrigation. SPECIAL FEATURES Convenient Operation Full Automatic, Semi-Automatic or Manual operation for controlling any watering need. Landscape Saver The unique ELECTRONIC CIRCUIT BREAKER in LAWN MASTER will check for valve failure. If a short is detected the controller will display SHORT and override that valve while continuing to water the remaining valves.
INSTALLATION CONNECTING THE WIRES TO THE CONTROLLER Remove lower panel covering, turn up and over. Line up terminal identification area with terminal screws as shown below. Connect the wire from valve number 1 to terminal slot number 1, connect the wire from valve number 2 to terminal slot number 2 and so on until all valves are connected. Connect the COMMON wire from the valves to the terminal marked COMM. If using a MASTER VALVE or PUMP START, see below.
PROGRAMS PROGRAMMING YOUR LAWNMASTER CONTROLLER DEFAULT PROGRAM When new from the factory: A default program has been installed in PROGRAM A for your convenience. This program is set to water all valves for 10 minutes every day at 4:00 AM. If this program works for your system simply set the time and day and you are finished. However, if you would like to customize your LAWN MASTER with your own unique programs, erase this default program by following the simple steps provided below.
Master Valve A master valve or pump start is sometimes used in systems. When selected ON the controller provides constant output to that terminal when valves are on. See MASTER VALVE HOOK-UP. (page 6) The LAWN MASTER allows you to select this option on each program. The default is OFF for all programs. To select your master valve ON: Press NEXT until MASTER is displayed (after last valve) Push ON to activate, push OFF to turn OFF.
TROUBLESHOOTING MANUAL OPERATION SEMI-AUTOMATIC This position will let you water your normal program cycle at any time. Each valve’s WATER DURATION will be operated for the program selected. Set dial to “SEMI AUTOMATIC” Push ON to start watering. Push OFF to stop watering. Push NEXT to advance to the next valve. Return the dial to “AUTO” after watering cycle begins. (The display will periodically show remaining time on the operating valve.) l l 1.

MEMORY PROTECTION Your programs are stored in a unique electronic device called “Non-Volatile Memory”. This protects your programs from being lost when electrical power is disturbed even without connecting a battery.
