General Water Control Information - Rinnai Infinity XR32 Operation & Installation Manual

GENERAL WATER CONTROL INFORMATION

Remote water controllers allow precise temperature control by the user. When used correctly, the hot
water unit will deliver the selected temperature, even when the water flow is varied, or more than one
tap is in use. Each water controller can be individually programmed, however the water heater can
only deliver one set temperature at any time. The available temperatures (°C) are as follows:
Kitchen Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C* ( 60, 65, 75°C Infinity HD models only )
Bathroom Controller:
Hot Water Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Bath fill Delivery: 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48°C
Whilst hot water outlets are open the set temperature may be lowered. However the set temperature
cannot then be raised above 43°C. In addition, transfer of 'priority' between water controllers is not
possible. These are safety features.
Suggested temperatures are:
Kitchen 50°C ~ 55°C* Shower 37°C ~ 43°C, Bath fill 39°C ~ 45°C
* Temperature may not be available on all installations. Rinnai water heaters can be programmed to deliver higher temperatures
via the kitchen water controller. Contact Rinnai for more details.
These temperatures are suggestions only. You may find higher or lower temperatures more
comfortable. Maintaining lower temperatures helps save energy. To obtain water temperatures lower
than 37°C simply add cold water.
Water controllers are an optional extra. 'Universal', 'Deluxe', and 'Wireless' water controllers can be
fitted. Universal water controllers allow temperature selection only. Deluxe water controllers allow
temperature selection, shower saver / bath fill, voice prompting and have a clock function.
Water controllers allow the water temperature to be set from the various locations where they are
installed. The temperature selected will be available to all outlets.
