Temperature Controls - Rinnai 26i Service Manual

TEMPERATURE CONTROLS

The purpose of a Temperature Controller is to enable the user to have localised control over the hot
water supply.
Used correctly, the hot water unit 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 four universal can be fitted with Rinnai water heaters. Universal Controllers allow temperature
selection only and one comes as standard with the water heater.
Deluxe Temperature Controllers are available as an optional extra.
These controllers have temperature selection, bath fill, voice prompt, and time clock functions.
When more than one universal Controller is used one may be set as the Master Controller to allow
temperatures above 50°C.
(ask Rinnai for more information)
Various water temperatures (°C) can be selected as follows:
Universal Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Master universal Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C (60, 65°C HD)
Deluxe 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
Deluxe Kitchen Controller:
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C (60, 65°C HD)
If a temperature of 43°C or higher is selected on any controller and this temperature is then decreased
to below 43°C and increased again whilst the water is running, the maximum selectable temperature will
be 43°C. This provides additional safety for the user.
Suggested temperatures are:
Kitchen 50°C - 65°C**; Shower 39°C - 43°C; Bath fill 39°C - 45°C
** This temperature may not be available on all installations.
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 37°C simply add cold water.
When multiple temperature controllers are used they allow the temperature to be set from various
locations by pushing the transfer button which gives that controller priority over the system. The
temperature selected by the controller with priority will be available to all outlets.
