Installation is extremely easy. The RAINMASTER FAVORIT comes delivered complete with flexible hoses for water connections, pressure tank, and shut-off valves. All controls are pre-programmed including inter-system Bluetooth communication for duplex and triplex operation.
The RAINMASTER FAVORIT system features the required “air gap” separating mains water from rainwater. Many local regulations require air-gap style backflow prevention, which is accepted in any jurisdiction.
In place of the pressure and flow control sensor, the RAINMASTER FAVORIT is equipped with a speed controller to run to a constant pressure. The variable frequency drive (VFD) regulates the speed of the pump to achieve the target pressure. This saves energy and improves performance while also running quieter.
Several RAINMASTER FAVORIT rainwater units can be connected in parallel and communicate with one another by means of a Bluetooth controller. Up to three units can be installed in parallel. Brilliantly, the individual units work together via the Bluetooth control, but each one is completely self-sufficient. As such, RAINMASTER FAVORITS can be installed in duplex or triplex with no programming required or additional set up. They just talk to each other and coordinate with redundant controls for the ultimate in reliability.
The RAINMASTER FAVORIT meets the strictest energy efficiency standards. The speed-controller regulates the flow rate of the pump in response to your actual needs.
Most pumps run at their maximum speed. Since there are usually only a few demands on the water supply, it is possible to save up to 40 % energy consumption by using a speed-controller or VFD.
| Flow rate | 1 GPM | 2.5 GPM | 5 GPM |
|---|---|---|---|
| Without speed control | 0.65 kWh | 0.73 kWh | 0.76 kWh |
| With speed control | 0.21 kWh | 0.58 kWh | 0.65 kWh |
| Savings | 68 % | 20% | 14 % |
A pump unit using a VFD runs at a significantly lower speed than an uncontrolled one, operating at a much quieter sound level. One RAINMASTER FAVORIT unit emits 45 decibels during the filling of a toilet tank, compared to 65 decibels by an uncontrolled pump.
The low speeds, at which RAINMASTER FAVORIT water systems predominantly work, lead to significantly less wear and tear on the electronic components and the pump.
Each RAINMASTER FAVORIT is wet tested in the INTEWA factory for their functionality, reliability, electrical and plumbing safety, leak-proof, and output values. After passing the quality test, a separate test report is generated for each unit before it is dispatched.
