Temperature Controls

The purpose of a Temperature Controller is to enable the user to have complete control over the hot water supply. Used correctly, the Infinity will supply hot water at the temperature selected, even when the water flow is varied, or when more than one tap is used. Adjustments to the operation of your hot water unit can be made with any of the Temperature Controllers. Each Temperature Controller can be individually programmed.

Up to three Temperature Controllers can be fitted with the Infinity 16i. One of these controllers comes as standard mounted on the water heater. Additional Temperature Controllers are an optional extra.

The controllers have temperature selection, water flow volume, and water supply temperature functions.

Various water temperatures (°C) can be selected as follows:

35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 50, 55, 600C

750C can be set on the dip switches.

When the remote is turned on the temperature will default to 400C.

While the hot water is running, the maximum selectable temperature will be 48°C. This provides additional safety for the consumer.

Suggested temperatures are:

Kitchen 50°C - 60°C; Bathroom 39°C - 43°C

These temperatures are suggested starting points for selection. You may find higher or lower temperatures are more comfortable. Maintaining lower temperatures helps to save energy. To obtain water temperatures lower than 35°C simply add cold water.

Up to three controllers can be used for one Infinity 16i. When multiple temperature controllers are used the only remote that can change the temperature is the one with priority. This is shown by the lit priority indicator. When the Kitchen Controller has priority the other remote’s priority indicator will go out. When the Bathroom Controller has priority the other remote’s priority indicator will flash. A different remote can only take priority of the system by pushing the priority button when the priority lamp is out. This means that while the Bathroom Controller has priority no one else can alter the temperature.

To take priority with the Kitchen Controller from the Bathroom Controller the priority button on Bathroom Controller must be pressed to give priority away.

The temperature selected by the controller with priority will be available to all outlets.
