Applications
The SIGMA rainwater unit developed by WISY is a complete rainwater harvesting system with integral self-priming pump, control system and automatic mains wa­ter top-up. It combines numerous individual devices to form a single package for installation in a utility room or basement.
SIGMA pumps the rainwater out of the storage tank and feeds it under pres­sure into the rainwater supply circuit. At the same time, SIGMA controls the entire rainwater harvesting system, monitors the fill level of the storage tank and automatically tops up the system with mains water when required. SIGMA is available with an optional level indicator
SIGMA is designed to supply toilet cisterns, washing machines and garden irriga­tion systems in single-family homes with clear, filtered rainwater.
Important preconditions for correct operation of the system:
● The suction line must be installed with a continuous rise from the rainwater storage tank to the SIGMA unit. The wall unit must be installed above the maximum water level in the rainwater storage tank.
● With a height difference of 3 m between the wall unit and the rainwater storage tank base, a suction line of up to 15 metres in length may be required (see diagram).
● The suction line must have an inside diameter of at least 1“ (2.54 cm).
● A floating fine suction filter FFSF (item SZ 9924) with non-return valve
is required in the rainwater storage tank
If the rainwater storage tank must be installed with a larger height differential or at a greater distance from the rainwater unit due to the site topology, WISY‘s OPTIMA / OPTIMAPlus rainwater units can be installed. OPTIMA rainwater units operate without a suction line and are designed to pump water over longer line distances/ height differences.
SIGMA cannot be used to supply outlets at a rate of less than 1 litre per minute (e.g. drip irrigation systems; outlets must close completely, the rainwater circuit must be leak-tight).
SIGMA is not suitable for pumping dirty rainwater or well water (which contains dirt or sand particles). SIGMA cannot be used to pump water out of a dirty rain­water storage tank. Improper use of the equipment can result in destruction of the pump.

Design and operating principle
The SIGMA rainwater unit draws rainwater from a storage tank and feeds it under pressure into the rainwater supply circuit. If the water level in the storage tank is low, the system automatically switches over to mains water operation.
A self-priming pump draws harvested rainwater out of the storage tank and pumps it to the appliances. If a valve at one appliance (e.g. toilet flushing sys­tem) is opened, the pressure in the rainwater supply circuit drops. The pump starts up when the pump starting pressure (1.5 bar) at the automatic switch is reached. When all valves at the appliances are closed again and there is no measurable flow through the circuit, the pump control system (automatic switch) shuts down the pump when operating pressure is reached.
Switchover to mains water top-up is fully automatic provided that the float switch in the rainwater storage tank is securely attached to the inflow tube (in­flow calming) at a vertical height of 30 cm above the base of the tank. If this „minimum water level“ is reached, the float switch in the storage tank closes. (Mains) water is now sucked out of the top-up tank integrated in the SIGMA unit.
The drop in water level in the top-up tank causes the float valve to open to allow inflow of mains water into the top-up tank. In the rare occasion that the mains water that is supplied to the top up tank is coming in with a very low pressure, it can happen that the pump is drawing more water from the top up tank than can be simultaneously replaced with mains water. The Water level in the top up tank is falling until it reaches a low point 3 cm above bottom level. At this point a safety control switches the pump off until the water level in the top up tank has reached a height of minimum 13 cm again. When the Water Level is rising above this Level the pump is automatically switched on again. When the valves at all appliances are closed again, the pump control system shuts down the pump as soon as operating pressure is reached (= max. delivery head).
The automatic switch provides dry run protection when there is insufficient water in the circuit.
It is possible to manually switch the rainwater unit over to pure mains water operation while maintenance work is in progress or when water of a particularly quality is required. Manual switchover is possible irrespective of the fill level in the rainwater storage tank. Mains water operation can be selected by means of an electric switch on the side of the automatic switch. If the switch is turned on, the self-priming pump automatically extracts water from the mains water top-up tank when an appliance valve is opened.

SIGMA with level indicator
Installation requirements
The SIGMA system must be installed by specially trained installation personnel, i.e. by properly qualified, approved installation specialists and electricians. This is a basic requirement for maintaining the validity of the manufacturer‘s guaran­tee.
The SIGMA unit must be installed above the backflow level in a frost-free room which has a floor drain. Special measures must be implemented if the unit is installed and operated below the backflow level. Please contact WISY AG‘s technical support team for advice about installation below backflow level.
The suction tube must be installed with a continuous rise up to the SIGMA wall unit. The tube must have an inside diameter of at least 1“ (2.54 cm).
With a height difference of 3 m between the tank base and the SIGMA unit, a suction line of up to 15 metres in length might be required (maximum values).
For a SIGMA unit with level indicator, the measuring lead (for the level indicator) must be installed with a continuous rise up to the wall unit.
The emergency overflow (DN 70) of the mains top-up tank must be permanently and securely connected to a drain (minimum DN 70). The room in which the SIGMA unit is installed must have a floor drain.
The water column between the bottom edge of the wall unit and the highest operating point (valve at appliance) must not exceed 15.0 m.
The wall unit and the supply lines must not be installed in locations which are exposed to substantial heat sources, as temperature rises in these components can cause the system pressure to increase and result in component damage.
Piping or hoses must be cleaned or flushed through before use to remove any deposits of dirt/dust caused by building work. Protective plugs must be remo­ved before pipes or hoses are connected.
Attention to backflow level and floor drain in the installation area

Connection to the indoor pipework
Installation of components in the rainwater storage tank
Installation
Line up the wall mounting kit horizontally and attach it to the wall. The wall­mounting bracket can be used as a drilling template. The distance between the holes is 28 cm. The wall unit can then be inserted in the groove of the bracket.
The connection between the wall unit and the rainwater supply circuit / mains water pipe must be high pressure resistant, flat-sealing and acoustically isola­ted. The ball valve with dirt trap (accessory hose connection set RW 78 00) must be used to connect the rainwater unit to the mains water pipe.
Clamp the float switch to the inflow calming tube in the rainwater storage tank at a vertical distance of between 30 and 35 cm from the tank base.
Attach the floating fine suction filter with the stainless steel hose clamp to the suction hose in the storage tank.
Route the electric cable for the float switch and the suction hose (and possibly the measuring lead for the level indicator) through a service duct into the utility room of the building.
Fill the suction hose with water, then attach it with hose nozzle and isolating valve to the suction end of the SIGMA wall unit with a hose clamp.
Do not install any flow restrictions (water meters, filters, drain cocks, etc.) in the SIGMA suction line.
Mains connection protected by RCD
The mains power connection (AC, single-phase, 230 V, 50 Hz) of the SIGMA rainwater unit must be equipped with a residual current device (0.03 A) and protected by a 16 A fuse.
Wire up the connecting cable of the float switch to the plug supplied. See photo­graph on left for correct termination of wires. Insert the plug into the grey socket outlet which is located on the underside of the wall unit.
All electrical work must be carried out in accordance with the safety instructions given on page 5.

Installation instructions for measuring lead
Connect yellow measuring lead to connector on the underside of the SIGMA wall unit
Universal, pneumatic fill level meter with capsule-type element and integrated electric pump for measuring fill levels in tanks. Steplessly adjustable to tank heights of between 100 cm and 250 cm (adjustable by the hexagon socket head screw); zero-point calibration of needle (adjustable by the Phillips-head screw). Measuring accuracy of the measurement mechanism is +/- 3% of full scale value. The electrically operated pump closes the measuring system at the top dead point. The needle remains stationary briefly and then drops very slowly down. The water stop air cushion produced in this way protects the capsule element.
Universal connection for the measuring lead (PE tube) with 8 mm outer diameter. Fill level is indicated in % irrespective of the tank shape.
Standard application is for water level height in the storage tank of between 100 and 250 cm and distances of around 10 m between the SIGMA wall unit with fill level meter and the rainwater storage tank (measuring lead length 13 m). Positi­on of normal use is vertical. Ambient temperature: 0°C to +40°C.
Protected against direct exposure to weather and solar radiation.
Install the measuring lead (yellow PE tube) with a continuous fall towards the tank. Do not bend the lead (to prevent water pockets!).
Install the rubber-insulated measuring lead with brass weight in the storage tank in such a way that it is suspended vertically and ends at approximately 5 cm above the tank base, then connect both tubes with the brass coupling.
To connect the measuring lead to the measuring instrument connector (on the underside of the SIGMA wall unit), assemble the individual components in the order illustrated in Figure 1 at the end of the yellow PE tube, insert the tube as far as it will go into the connector and gently tighten the hexagon bolt.
Device setting instructions
Remove the cover from the SIGMA unit.
Precisely adjust the measuring range (corresponds exactly to the maximum water fill level in the storage tank up to the overflow) on the adjustment scale using the hexagon socket head screw (failure to do this properly will result in measuring errors!).
Use the zero-point calibration screw to position the needle at „0“. Turn the screw by maximum one revolution to the left or right until the needle is pointing to „0“. If the tank has already been filled and the pump started, the measuring system will need to be „depressurized“ before the zero point can be calibrated. This can be done by detaching the measuring lead from the connector at the wall unit.
Description of level indicator unit
A measurement of the fill level of the storage tank is triggered only if the SIG­MA pump starts up. During the pneumatic measuring process, the hydrostatic pressure is measured. This varies depending on the water level in the tank. The pressure is generally measured at a height of 5 cm above the tank base and is converted to a fill level percentage on the clock dial.
The pump of the measuring instrument is used to build up pneumatic pressure in the measuring system until this pressure is equal to the water pressure applied to the base of the tank. The needle is now in its maximum position. The pressure generated by the pump has displaced the water column from the measuring lead suspended in the water (black rubber hose). Bubbles of air escape from the end of the hose on the tank base and the needle remains temporarily in the measurement position. Once the SIGMA has returned to its „normal position“, the needle gradually drops back to the „0“ position.

Indication errors and causes
● Needle does not move when measurement is taken / drops very quickly back to 0: Leak in connections or connecting lead, „depressurize“ the measuring system (see device setting instructions)! Hold a finger over the measuring instrument connector on the wall unit and start SIGMA by pres­sing the RESET button on the automatic switch (in wall unit)! If the needle moves to its maximum position, the measuring instrument and the connec­tions inside the wall unit up to the measuring instrument connector are OK. The connections and connecting lead must be inspected for leaks!
● Needle moves to beyond 100% position: The measuring lead is blocked or bent, or the measuring range is set incorrectly.
● Indication error: The device is incorrectly set. Check the fill level in the tank, correct on the adjustment scale!
Maintenance and servicing
Inspections/tests at 6-monthly intervals:
● Inspect the SIGMA system and the water circuit connections for leaks
● Check the system pressure indication
● Test the pump start and stop points at the automatic switch
● Test mains water operation, e.g. by setting the switch on the side of the au-
tomatic switch to „mains water mode“ and closing the isolating valve at the suction end
Inspections/tests at 12-monthly intervals:
● Inspect the dirt trap at the isolating valve of the mains water connection, clean the trap if required (call in a specialist if necessary)
● Inspect the floating fine suction filter in the rainwater storage tank and clean if necessary from ground surface level using a water jet or a long-handled brush (call in a specialist if necessary)
Replacement:
● The solenoid valve at the mains water outlet must be replaced by a specialist after the system has been in operation for 10 to 15 years.
Repairs
All repair work must be carried out by the manufacturer or by contractors who have been explicitly approved by the manufacturer. Repairs, modifications to components or modifications to factory-assembled SIGMA components carried out by unauthorized persons shall invalidate the guarantee!
The SIGMA rainwater unit must be disconnected from the mains power supply before any maintenance work is carried out on the open storage tank. Compliance with the safety instructions (see heading „Safety instructions“ in this document) is absolutely essential!
