i Introduction The T oro W ireless RainSensor system, model TWRS for rain sensing and TWRFS for rain and freeze sensing, is a powerful water conservation and management tool that connects your automatic irrigation system to actual environmental factors vital to the health and maintenance of your landscape.
1 The wireless sensor system is comprised of a programmable, weather-resistant receiver module and a sensor module with built-in transmitter . The receiver installs next to the irrigation controller a.
Getting Started The wireless rain sensor system is designed for easy installation, setup and years of trouble-free operation. In most cases, the system components can be installed and fully operational within minutes. All you will need is a Phillips screwdriver and basic do-it-yourself skills.
3 The sensor is adjusted to the preferred rainfall activation level. The sensor is installed using the Quick Clip TM mounting bracket or pipe-mount adapter . The operating features are set to your preferences. A sensor installation site is chosen and the system is tested again to verify operation.
4 Receiver Module F eatures 1 – Setup Button – Accesses the sensor system operating features. 2 – Adjust Button – Scrolls through and selects settings within the system operating features. 3 – Mast Antenna – Adjusts easily for best signal reception.
Installing the Receiver Module Important: Installation of this product must comply with national and local building and electrical codes. For assistance, contact a professional irrigation system contractor in your area. The receiver module is suitable for either indoor or outdoor installation.
6 Connecting the Receiver Wir es CA UTION: The receiver r equires continuous 24 V ac power f or operation. Connecting to 110 V ac or higher will result in irr eparable damage. Ensure power to the contr oller has been remo ved prior to connecting the r eceiver wires.
For a normally-open sensor , attach the Y ello w wire to the remaining sensor terminal. T ape back the Brown wire. See Figure 3. 4. Attach the Red wires to the 24 V ac terminals. Important Most controllers with sensor connections also provide a control switch to bypass sensor operation if necessary .
Initial System T est Before installing the sensor module, test the sensor at close range to verify operation. Once this test has been completed satisfactorily , the sensor module can be installed. If a problem occurs during the test procedure, refer to “ T roubleshooting ” on page 22.
9 Sensor Module F eatures 1– Rain Threshold Adjustment – Adjusts the rain sensor to accumulate 1/8", 1/4", 1/2" or 3/4" (3mm, 6mm,12mm or 19mm) of rainfall before signaling the receiver to hold watering. (Factory default setting 1/4" (6mm).
10 Installing the Sensor Module Choosing the right installation site for the sensor module is the key to getting the maximum benefit from your sensor system. Select a sensor installation site that provides the following conditions: • Unobstructed exposure to rainfall–away from overhangs, tree branches, etc.
11 3. Adjust the Rain sensor to the preferred rainfall threshold activation point. The settings are indicated in 1/8", 1/4", 1/2" and 3/4" on one side of the cap, and 3mm, 6mm, 12mm and 19mm on the other . First, turn the cap to align the stationary pin with the vertical slot.
12 A pipe-mount adapter is provided to enable sensor installation on a secured section of 1/2" (13mm) diameter Schedule 40 PVC pipe. Note: Metal pipe or conduit may interfere with radio signal transmission and is not recommended. Remove and replace the Quick Clip bracket with the pipe-mount adapter .
Freeze Sensor Site Selection In addition to the rain sensor site conditions listed on page 10, the following conditions are necessary to ensure optimum freeze sensor operation. For best results, the sensor should be: • Located in the coldest portion of the landscape.
Set T emperature Activ ation Threshold (TWRFS models only) The freeze sensor temperature activation threshold is adjustable from 35°F to 45°F or 2°C to 7°C. When the air temperature reaches the threshold setting, the freeze sensor activates the receiver .
W ater Conser vation F eature – By simply choosing the Minimum, Medium or Maximum conservation level that corresponds to your landscape’ s soil type and the sensor location, a dry-out period, adjusted for actual rainfall duration, is inserted after the sensor system resets to delay the resumption of automatic watering.
Smart Bypass F eature Pressing the Smart Bypass button switches an active sensor system Off and places it in the Bypass mode. When the sensor is bypassed, the controller resumes automatic watering operations as scheduled. The Sensor Status indicator and the Bypass display prompt will flash to indicate when the sensor system is in the Bypass mode.
17 Signal Strength Display This feature displays sensor signal strength on a digital scale ranging from 0.0 to 10.2 1. Press the Setup button as needed to display the antenna icon and the digital readout. The display will indicate the strength of the last received signal.
Dry Out F eature The Dry Out feature is provided to override the W ater Conservation baseline level, allowing the dry-out delay period to be set in 0.5-day increments from 0.5 to 4.0 days. Note: Before using the Dry Out feature, allow the sensor system to normalize by cycling through rain and/or freeze activation several times.
Loss of communication If the sensor system does not communicate within a 24-hour period, it will remain in its current state (Active or Monitor). T o alert you to this condition, the Attention Required symbol will be displayed. The Antenna symbol and current air temperature (TWRFS only) will be flashing and the signal bar indicator will be cleared.
T urn the Recei ver Module Off and On 1. T o turn the receiver module Off , press and hold the Adjust button until two dashes are displayed (approximately 5 seconds), then release. 2. T o turn the receiver On , press the Setup button two times . The receiver will return to the normal display mode within approximately 10 seconds.
Sensor Module Battery Replacement 1. Unscrew and remove the bottom cap from the sensor housing. 2. Grasping the edges of the circuit board assembly , carefully slide the circuit board assembly out of the housing. 3. Remove the battery cover and batteries.
T roubleshooting If you encounter problems at any point in the installation process, or the components do not seem to function properly , try the Troubleshooting procedures first. If the problem is not listed or the remedy does not resolve the problem, call the T oro Irrigation help line at 1-800-664-4740.
The recei ver display is blank. • Check the 24 V ac power connections. The red power wires from the receiver must be connected to the controller ’ s 24 V ac power source. Make sure the power wires are not connected to the station or pump/master valve terminals.
