Temperature Controls - Rinnai HDC 1600i Low NOX Installation And User 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 and/or Deluxe Temperature Controllers can be fitted with Rinnai
water heaters. Universal Controllers allow temperature selection only and one comes as
standard with some of the water heaters, Deluxe Temperature Controllers are always an
optional extra. These controllers have temperature selection, bath fill, voice prompt, and
time clock functions. When more than one Universal Controller is used just one may be
set as the Master Controller to allow temperatures above 50°C.
Various water temperatures (°C) can be selected as follows:
Universal Controller "MC-91":
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50°C
Master Universal Controller "MC-91":
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C ( 60, 65°C, 75°C HD )
Deluxe Bathroom Controller "BC-100V":
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 "MC-100V":
37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 48, 50, 55°C ( 60, 65°C, 75°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 45°C; Shower 39°C - 43°C; Bath fill 39°C - 45°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 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.
