GENERAL INFORMATION DESCRIPTION: The RainwaterTechnoJogy Rainwater System Controller manages all of the functions required in a typical residential or commercial rainwater collection system:

WATER LEVEL MONITORING: The Rainwater System Controller continuously measures and displays the water level in the rainwater tank, both as a numeric percentage and as a bar-graph.

BACKUP: The Rainwater System Controller activates a secondary water source when there is insufficient rainwater to meet demand. Three different backup schemes are supported: backup water can be delivered directly to the rainwater storage tank, backup water can be drawn from a small secondary tank that is refilled with a float valve, or backup water can be directly connected under pressure using a 3-way valve and a backflow preventer. When the backup system is activated, a backup indicator is lit on the control panel.

TRANSFER: The Rainwater System Controller activates a pump or valve to transfer water from the rainwater tank when the tank is full, providing an alternative to a simple gravity overflow system. This function can be used to pump water to a secondary storage site, or to disperse excess water to a remote location. Manual transfer is also supported.

RINSE: The Rainwater System Controller periodically rinses rainwater filters at intervals determined by the volume of water filtered, thereby reducing filter maintenance. This function is only applicable for filters that have provision for a rinse nozzle.

DRAIN: The Rainwater System Controller automates "first-flush" systems that coilect the initial runoff from a roof in a small holding tank This function will operate a drain valve or pump relay to evacuate the first-flush tank a pre-set number of days after the last rainfall. When rainwater is stored solely for runoff control, this function can be used to dump the primary rainwater tank several days after the last rainfall.

SERVICE: The Rainwater System Controller warns of the need for routine maintenance of filters, ultraviolet sterilizers, or other system components by illuminating a service indicator and operating a control relay after a pre-set time interval. System malfunctions also activate the service indicator and relay. For critical installations, the relay can be used to control an alarm or autodialer.

COMPONENTS: The Rainwater System Controller consists of a tank-mounted sensor system and a sophisticated microprocessorbased control station. The sensor control box can be located up to 150 feet from the control station and the two components are connected with standard underground irrigation cable. The entire system is powered by a low-voltage transformer which permits safe and easy installation without an electrician.

The attractive, splash-resistant control station can be installed in a living space, office, outbuilding, or mechanical room. A backlit LCD display screen eliminates the need for supplemental lighting at night and clearly displays the water level and the status of all system functions. With a few minutes practice, the intuitive programming system makes it easy to view the status of any system function or modify any setting in English, French, or Spanish without consulting a manual.

The sensor system has been engineered to meet the demands of rainwater storage applications where particulates and turbulence often make other types of level measuring devices unreliable. The standard sensor is designed for tanks up to 10ft tall (9 ft water level), but a longer version is available for tanks up to 20 ft (19 ft water level).

INSTALLATION The sensor control box should be mounted 4" to 6" above the ovelilow level of the water storage tank. Position the control box at this height so that the side with one wire connector faces up and the side with two wire connectors faces down, and drill pilot holes for the mounting screws. Then screw the box in place by hand to avoid damage to the case or mounting feet. NOTE: The sensor wires must be spaced at least 12" from access ports and tank walls made of steel or reinforced concrete.

Unscrew the cover from the sensor control box. With the stainless steel probe hanging approximately 1/2" above the bottom of the tank, cut the red and white sensor wires at the height of the two outer (upper) terminals. Strip about 1/4" of insulation from the wires, and attach the wires to the terminals. The sensor wires should be peliectly straight when they are drawn taught by the weight of the stainless steel probe: work out any kinks or bends that might have been created. Then attach the three plastic spacers uniformly separated as shown.

Run a length of two-conductor #18 underground irrigation cable from the sensor control box to the point where the control station will be mounted. Remove the jacket from the end of the cable near the sensor control box, strip about 1/4" of insulation from the wires, and attach the wires to the two inner (lower) terminals. Replace the cover, carefully starting the screws so they don't strip the threads, and securely tighten the screws so that the cover gasket is fully compressed. Then tighten the nuts on the cable clamps so all wire entries are sealed watertight.

The low-voltage transformer can plug into any unused receptacle within the building where the control station will be mounted. Determine the most suitable location and run a three-conductor #18 cable to the location where the control station will be mounted, but don't plug in the transformer yet!

Run low-voltage wires to the location where the control station will be mounted from any electric valves or relays to be used for the backup, transfer, rinse, and drain functions. If these are to be buried underground, #18 irrigation wire should be used. All relays and valves must be 24VAC and their combined power consumption must not exceed 30 watts.

Mount the sensor control box 4" to 6" above the overflow level of the tank. Cut the sensor wires so that the sensor is

suspended 1/2" above the bottom of the tank

Position the control station at the desired position and make a mark on the wall at the top center of the case. Set the control station aside, make a second mark 1-1/8" below the first mark, drill a pilot hole at the mark, and attach a screw, leaving the head protruding approximately 3/16". Remove the bottom cover plate to expose the terminal compartment and hang the control station on the screw. Level the box and mark screw centers through the slots at the bottom of the screw pockets located at the lower left and lower right corners. If the cables will be hidden inside or behind the wall, insert a nail through the rubber grommets to mark the wall for cable holes. Remove the control station and drill holes for the cables and pilot holes for the screws. Pass the cables through the holes in the wall and through the grommets, re-hang the control station, and attach the two bottom screws.

Remove the jacket from the ends of the cables, strip about 1/4" of insulation from the wires, and insert each wire into the appropriate terminals as shown in the illustration and printed inside the terminal box cover (C=common, G=ground, T=transfer, P=power, B=backup, R=rinse, D=drain, S=service, unmarked=sensor). Tighten the terminal screws using the small screwdriver supplied.

Attach the power cable to the transformer and plug in the transformer. The power light and the display screen on the control station should both be lit. If not, check to see that the green power indicator on the transformer is lit. If the transformer power indicator is not lit, check for power to the receptacle. If the transformer power indicator is lit, check the power cable connections on the transformer and inside the control station. If these are secure, try changing the fuse on the main circuit board which is accessed by removing the four screws at the corners of the front panel. If the power indicator is still not lit, disconnect the power cable and check for continuity in the wires.

INTRODUCTION TO THE PROGRAM MODE: When power is first connected, the green Power indicator will light and the display will identify the system software version. After a few seconds the system will enter the user mode where the screen would normally display the water level in the rainwater tank. Since the tank depth has not yet been entered, the water level cannot be determined so the display will show the error message "depth =0" and the red Service indicator will light. The tank depth and all other settings are entered in the program mode which is activated by depressing the Program button for five seconds. After the desired settings are entered, momentarily pressing the Program button again will return to the user mode. The system will also return to the user mode if no buttons are pressed for 30 seconds. The exercise below will introduce all the system settings available in the program mode.
