The Weathermatic SLM4 4-Zone Module is only to be used with the PL1600 & SL1600 Controller.
SMARTLINE controllers each represent the richest feature set in their respective class. By adding an SLW Series On-Site Weather Station; a SmartLine controller enters a class of its own. It has been said; "You buy the product only once; but you buy the water every month." This fact alone is a great reason to invest in SmartLine. With no service provider dependence; no recurring maintenance; and no user fees; SmartLine pays dividends on your one-time investment every single month.
SmartLine controllers and SLW Series On-Site Weather Stations deliver an excellent ROI (Return On Investment) through a patented water saving process (U.S. Patent No. 6;314;340).
WEATHERMATIC SMARTLINE SERIES CONTROLLERS & ACCESSORIES:
SL1600 SmartLine Controller
SLM4 SmartLine 4-Zone Module
SLW10 Residential On-Site Weather Station
SLW15 Wireless On-Site Weather Station
SLW20 Commercial On-Site Weather Station
SmartLine takes weather readings, like temperature and rainfall, every 8 seconds to develop the optimum watering schedule for the plants and turf. By making 365 annual adjustments, rather than 0-12 adjustments, SmartLine reduces water usage by 20-50%, improves plant health and beauty, eliminates runoff, and puts an end to water worries.

Hot-swappable modules can be added/removed without resetting or unplugging the controller
Backlit LCD and door latch on SL1600; SL1624; SL 4800
2 run modes: Standard mode runs user input zone run times; Auto Adjust mode requires SLW Series On-Site Weather Monitor to calculate weather based run times in replacement of user input zone run times
Rain/Freeze sensor bypass/active button located on face panel displays sensor status with red/orange/ green tri-color LEDs (red indicates sensor is prohibiting irrigation; orange indicates paused for run/soak or zone-to-zone delay; green indicates normal operation)
4 programs: A; B; C; program D can operate concurrently.
8 start times per program
Non-volatile memory retains programs in the event of power outage
Zone run times settable from 1 minute to 9 hours 55 minutes with operation count down displayed in hours; minutes; and seconds (zone run times replaced with weather based calculated values in Auto Adjust mode)
Watering day selections of custom days of the week; odd/even; or interval days
Omit settings of omitting times of the day; omitted days of the week; and up to 7 omitted calendar dates
All models except the SL800 are outdoor/indoor rated with a mounting bracket included.
