GENERAL WATER CONTROLLER INFORMATION

Temperature 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°C, 65°C, 75°C 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 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 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' and 'Deluxe' water controllers can be fitted.
Universal Controllers allow temperature selection only. Deluxe controllers allow temperature
selection, bath fill 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.
Universal (MC-91-2A) and Deluxe (MC-100V & BC-100V) Controllers - available configuration:
A maximum of 4 water controllers can be fitted. Any combination of the deluxe, universal and wireless
controllers can be used with the following limitations.
Only ONE master controller can be installed. This can be MC-100V, a MC-91 (when programmed as
a master controller) or a MC502S (wireless) controller.
Up to TWO BC-100V water controllers can be installed.
The FOURTH water controller in any installation MUST BE a MC502S (wireless) or a MC-91.
