User's Manual
The RFS5 is a wireless rain/freeze sensor operating on
a 900 MHz bi-directional frequency. Maximum range
is 1500 feet (457m) Line of Sight (LOS). The RFS5
is operable with all ProLine® models and firmware
versions. The RFS and RFSHUB-5 are “pre-paired” or
synced at the factory for your convenience.
1. Install the RFSHUB-5.
The RFSHUB-5 is the wireless transceiver that
communicates with the RFS5. The RFSHUB-5 is supplied with
your RFS5. To install in your ProLine® controller, open the
control panel/door on the 1600/4800 models. On the 800
model, remove and discard the “hub cover panel” from the
back of the housing.
Insert the RFSHUB-5 into the
mating pin connector holes.
Be careful not to bend the
connecting pins. Secure the
RFSHUB-5 to the housing with
the supplied flathead machine
screw. The RF antenna will hang
down inside the 1600 or 4800
model’s housing. On the 800
model, allow the RF antenna to
hang underneath the controller.
Make sure AC power is supplied to the ProLine® controller and
then proceed to Step No. 2.
2. Initializing RFS5 rain/freeze sensor
a. While standing in front of the
controller, press the rain switch
on the top of the RFS5 for 15
seconds; then watch the LED
(which can be seen by openings
the cover at the bottom of the
RFS5). You will see 4 blinks. All
blinks should be Green.
The 4th (final blink) indicates the
strength of the RF communication.
If the 4th blink is Red, you do not have a satisfactory RF
communication. Move the RFS5 to a dierent mounting
location and repeat the diagnostic procedure.
Note: The 1st LED blink indicates the strength of the 2 AAA
lithium batteries in the RFS5. A Red blink would indicate a
need to replace the batteries. Capable life for the lithium
batteries is around 10 years. If the 2nd and 3rd blinks are Red,
complete replacement of the rain/freeze sensor is required.
Note: A separate RFS5 rain/freeze sensor is required for each
ProLine® controller that you are installing.
Determine communication range and choose location
While still standing at the controller, press the rain sensor wick
for 15 seconds. If you have RF communication, the antenna
icon on the ProLine® display should be blinking. Note: The
blinking will continue for 5 minutes after any communication
from the RFS5. After 5 minutes, the antenna icon will remain
static until the next communication. Press the blue “Rain/
Freeze Sensor” button, on the right side of the controller
panel, so that it is in the “On” position. The LED should be
Green. If it is Red, repeat Step 2. In addition, the operating
panel on and PL1600 or PL4800 must be closed so that AC
is present. You will get a communication error if the panel is
showing NO AC.
3. Mounting the RFS5
a. Decide on a good mounting location for your RFS5 wireless
rain/freeze sensor. Mounting is preferred in direct sunlight
with good airflow. Additionally, the location must have
open access to rainfall (cannot be covered by any overhead
obstruction such as trees, roofs, etc.). Mount the RFS5 as
close as possible to the controller. Obstacles such as earth,
hills, walls or other structures will reduce the maximum
operating range of the RFS5. Refer to the LED inside the
bottom of the RFS5 to verify communication and to check
operating range at a specific
location. Extreme conditions may
prevent wireless communication.
b. Attach mounting bracket to a
smooth surface using the two
mounting screws (supplied) or
attach to gutter using the wing
nut provided. You may choose
to remove the mounting bracket
from the bracket arm for easier
installation. Make sure the RFS5 is fixed in a vertical position.
Tighten all wing nuts to make sure unit is held vertical.
