The Rinnai Wireless Controller (with transceiver) is the easiest and quickest to install, and suitable for retrofitting into existing homes.
Digital controllers allow you to select the exact temperature of the hot water at the tap within the controller temperature range. This has a number of benefits:
- Safety, especially if you have young children, the hot water can be pre-set to a child-safe level.
- No need to mix hot and cold water, this reduces temperature spiking when another tap in the building is turned on
- Allows diagnosis of problems (such as gas supply disruption) when the appliance is serviced by displaying 'error' codes, which the service person can utilise.
