2. Features

Installation
The light-weight, slim, and compact form enable easier, improved appearance installations. The
remote controls (where fitted) are connected to the appliance by 2-core non-polar cable, ensuring
easy wiring and eliminating misconnection problems.
Low Noise Level
Low noise level design enables these appliances to be installed in units, flats, townhouses, and
other high density residential areas with little concern about noise disturbances.
Safety
Various safety devices controlled by a micro-computer ensure complete safety. Also, the anti-
frost device (where fitted), automatically prevents the water inside the appliance from freezing by
using small electrical ceramic heaters connected to the pipework at strategic locations.
Economy
Direct electronic ignition to the main burner eliminates wasteful pilot gas consumption. The
combustion fan rpm is proportionally controlled with gas consumption. This maintains high energy
efficiency as the gas consumption changes.
Water Supply Control
The water supply capacity varies proportionally from 2.7 L/min to 24 L/min. A suitable volume of
hot water can be supplied throughout all seasons by the water flow control device and water flow
servo mechanism. REU 2425W model will supply up to 24L/min, (maximum unmixed), controlled
by an automatic electro-mechanical water flow device. See "Water Flows" on page 16 for precise
details on water flow.
Water Temperature Control
With a remote control connected, the hot water control range is between 37°C and 50°C (in 12
steps). With or without a remote control connected the outgoing hot water temperature is fixed to
50°C maximum with no remote. This means that the Infinity Series can be set to comply with
various State laws on temperature control in homes, child care centres, and elderly care centres.
The maximum temperature selectable on the bath remote control is 50°C (this is a safety feature).
Over Temperature Protection
All Infinity models incorporate a device to prevent the hot water temperature exceeding the pre-
set temperature by more than 3°C.
Temperature Locks
With the remote control(s) connected, the pre-set water temperature can only be altered between
37°C and 43°C while the hot water is flowing. This helps to avoid inadvertently increasing the
temperature to a hazardous level whilst someone is in the shower. While the water is flowing, the
remote control(s) can be turned off, but not on again.
