oPL4800 (G5) = 4 programs (Program A, B, C, D), 5 solenoids including MV
Q3: Can your controller operate both normally open and normally closed master valves?
A3:
•Date Code: Pre-2018
oPL1600/PL1620/PL4800 = NO
•Date Code: 2018 - Current
oPL1600/PL1620/PL4800 (G5) = YES. This option is set up under the ADVANCED
Menu.
Q4: Does the existing controller need to be upgraded to work with the aircard?
A4: SmartLink requires a compatible ProLine control panel. To find your ProLine control panel
version, go to the Advanced Functions > About menu and select the option to view your control
panel version.
•SmartLink is supported by ProLine control panel versions 5.10 and greater. If you have version
5.10 or greater, no changes are required.
•ProLine control panel versions older than 5.10 cannot be used and require a new control
panel. Control panels can be purchased through your Authorized Weathermatic Distributor. It
is not necessary to replace the entire controller. You can simply remove the panel from the
hinge and replace with a new compatible panel.
Q5: Can the controller panel in a PL1600 be swapped for a controller panel in a PL4800,
SL1600 or SL4800 or SL9600TW?
A5: Yes. All ProLine and SmartLine controller panels are interchangeable.

Page 2
Q6: Which RFS5 Rain/Freeze sensor works with the PL800? With the PL1600?
A6: The ProLine PL800 and PL1600 is designed for use with either the RFS1 or RFS5 rain/freeze
sensor.
Q7: Does the PL800 work on SmartLink-Commercial?
A7: No. The ProLine SL800 DOES NOT currently operate with a the SmartLink Aircard.
Q8: Does the PL800 work on SmartLink-Residential?
A8: No. The ProLine PL800 DOES NOT currently operate with a the SmartLink RESIDENTIAL
Aircard.
Q9: Does the ProLine PL1600 or PL4800 controller work on SmartLink?
A9: Yes. The ProLine PL1600 and PL4800 can be connected to the SmartLink network using a
SmartLink aircard with a subscription or a SmartLink Residential bundle.
Q10: What is the difference between the ProLine controller and the SmartLine controller?
A10: The ProLine controller has a Spanish language button on the panel. The ProLine controller
does not have an ET (Smart) programming options. Some ADVANCED Features are available as
options using the Panel Dial. All other features are the same as SmartLine.
Q11: Does the ProLine controller work with flow sensing?
A11: Yes. The ProLine PL1600 and PL4800 can be connected to a flow sensor via it’s SmartLink
aircard with a SmartLink flow subscription.
Q12: Does a SLW "weather station" work with ProLine?
A12: ONLY the rain/freeze functions will operate on a SLW weather station if used with a
ProLine controller. The local weather data does NOT function when an SLW weather station is
used on a ProLine controller.
Q13: Is there an extended warranty for ProLine/SmartLink equipment?
A13: Yes. An extended warranty is available for purchase which extends the warranty to cover
fire, theft, vandalism and product failure.
Q14: What is the 9-volt battery connection in the compartment behind the front panel used
for?
A14: Connect a 9V battery to view and program the control panel when it is "open" or removed
from the housing. All ProLine controllers use a Real Time Clock/Calendar instead of a backup
battery to maintain correct time/date during a power outage. ProLine non-volatile memory
also maintains programming during power outages.

Page 3
Q15: The ProLine panel is displaying the current time and date, yet I can’t I turn on a station.
A15: The panel is ajar (open) and the display is being powered by the 9V battery. The controller
will not run until the panel is completely closed.
Q16: My rain sensor shows ORANGE, but it isn’t raining, and the controller won’t run a
program.
A16: This is a feature of the ProLine controller called SLW Delay that extends the “dry out”
period for an additional number of hours. The SLW Delay under the SENSOR OPERATIONS
allows the user to adjust the factory set 48-hour watering delay that will occur after a rain
event shutdown if you are using a RFS Rain/Freeze sensor.
Note: The SLW DLY begins after the SLW rain sensor has reset (is dry) following a rain event.
Accumulation of new water deficits will not begin until after the SLW Delay has cleared.

Q18: What happens to the remaining run time if the program is interrupted by an omit time?
A18: The omit settings are used to set a watering blackout period. For example, if you live in a
municipality that restricts outdoor watering between 10:00 am and 6:00 pm, you can blackout
that time period. If a watering program in progress is paused for a blackout period, the
ORANGE LED will display on the front panel during the pause. The watering cycle will
automatically resume at the end of the blackout period.
Q19: How do I create a "Grow-In" program for newly seeded lawn or new sod?
A19: You can create a "grow-in" program that will allow for watering with multiple daily starts.
The number of days the Grow-In program runs is user defined. Once the controller has reached
the user defined days, the controller will automatically revert to the Default program.
First, set up your normal watering program for an established landscape and activate the RFS
rain/freeze sensor. The next step is to save this program for future retrieval. Turn the dial to
Advanced Functions, press the DOWN button to get the Default screen. Press the Next button
to view Store in the display. Press Next button one more time and wait until the screen shows
Complete. Then turn the dial back to Run. You have saved the Default program. Now, change
your program(s) to the desired grow-in settings.
When you have finished programming the Grow-in program, turn the dial to Advanced
Functions, press the DOWN button to get to the Grow-in program. Press the Next button to set
the number of days to use the Grow-in program. Then turn the dial back to Run. You have
saved the Grow-in program.
Q20: My ProLine controller runs the same program over and over. Is something wrong?
A20: Check the Set Daily Start Times settings. Turn all other seven start times to OFF if do not
need more than one start time. If you have more than one start time, they should not be the
same time. To turn a start time to OFF, hold down one of the arrow buttons until you see OFF
shown in the display.
Q21: What is the battery icon in the ProLine display used for?
A21: The battery icon in the display indicates to different setting based on the dial position.
When the dial is in the Manual Program, Multimeter, Valve Locator, Sensor Operations or Run
Soak Cycles position, the battery icon reflects the battery strength of the RFS Rain/Freeze
sensor. When the dial is in all other positions, the battery icon reflects the strength of the 9V
battery installed in the access compartment in the back of the panel. ProLine Controllers use a
Real Time Clock/Calendar instead of a backup battery to maintain correct time during a power
outage. For the PL1600 and PL4800, the display will show a blank battery icon in the display
until/unless a battery is installed in the controller. Battery usage is only necessary for
programming when the control panel is removed.

Page 5
Q22: Why do I not see a battery strength icon for the RFS rain/freeze sensor when I turn the
ProLine dial to determine RFS battery strength? (left side of controller)
A22: The icon will disappear if the daily communication does not occur. You might have a
communication problem with the RFS unit. If you have any blank screens, then go to the RFS
unit and perform the diagnostic test as described in the Troubleshooting section of your
manual. The icon will return by itself if the controller receives a rain or freeze message from
the RFS or if the battery(s) in the RFS have a reportable change in strength. You can restore the
icon by holding down on the rain tab on top of the RFS for about 10 seconds.
Q23: How do I keep the run times from violating a local watering regulation?
A23: You can use the OMIT feature on the dial to blackout any restricted watering hours, days,
or dates. The Set Watering Days position on the dial also allows you to select specified weekly
days or odd/even days to an interval of days.
Q24: Why is my system repeating a watering cycle?
A24: Possible causes:
1) More than one Daily Start Time has been set for each program. The program will start at the
designated start time and run all zones assigned to that program in consecutive order. To turn
off extra start times, turn the dial to the Daily Start Times position and use the Next button to
view all start times for each program (A, B, C and D). Use either arrow button to advance to the
OFF position for each start time.
2). Run/Soak feature has been set in the Advanced Functions position causing the controller to
cycle multiple times so that the proper amount of water can be applied without creating runoff.
If you are using Run/Soak, the controller will automatically divide run times to minimize water
run-off.
Q25: How do I start a manual watering program in my ProLine controller?
A25: There are three ways. If you want to run all programs for the scheduled run time
programmed in the controller, just push the RUN MANUAL PROGRAM button at the top of the
controller. It will run all programs and return to the Auto-Adjust mode by itself. If you want to
select a single zone, you can turn the dial to MANUAL ZONE, use the arrow buttons to enter a
run time for the zone and then return the dial to RUN to start the operation. You can also use
the MANUAL TEST position on the dial to quickly run through all zones with time assigned.
When you turn to MANUAL TEST, the screen will display a 10 second run time for all
stations. You can change this time using the arrow buttons if you like; then return the dial to
RUN to start the operation

Page 6
Q26: What if my system did not water at a scheduled time when operating with the ProLine
controller?
A26: Check the ACTIVE LED. If it is RED, a rain or freeze sensor has shut down operation. It will
resume watering at the next scheduled start time.
Q27: What does the PAUSE indication mean on my ProLine controller?
A27: It means that your controller has temporarily paused irrigation due to a setting in the
programming for Omit Time, Rain Delay or Run/Soak to prevent water runoff.
If you are using an RFS rain/freeze sensor, the controller will also pause for a period of time (48
hours is default) after a rain sensor shutdown. The controller will resume watering at the first
scheduled start time after the pause. If you want to delete the 48-hour pause, just press the
sensor button to put the unit into bypass and then press the button again to put the sensor
mode back to active. The LED will be green. The controller will also show PAUSE momentarily
when it switches from one zone to another zone.
Q28: Why does my ProLine show zero zones?
A28: Possible Causes
(1) Try a different module. You could have a defective module.
(2) Modules must be installed from left to right with no open module positions in between
modules.
(3) AC must be present before the controller will recognize newly added modules. Make sure
the panel is tightly closed and the 9V battery is not connected and try again.
(4) If none of the above works, try a Total Reset of the controller as explained in section 7.1 of
your manual.
Q29: Does the SL1600/1620 have a ribbon cable?
A29: No, there is not a ribbon cable connecting the faceplate to the controller. The controller
clicks in and makes connection directly to the housing.
Q30: What does "NO AC" indicate?
A30: If your display indicates NO AC indicates the control panel is not being powered by the
normal 24v AC power.
Common causes:
1) Panel door is open
2) Fuse if blown in controller
3) Transformer is not working
4) Power source (outlet or breaker) is not functioning
While the NO AC is displayed, the controller is on 9V battery power and will not operate zones
or run your system.
