Rinnai INFINITY® Kitchen Deluxe Controller



Designed for kitchens and laundries

The Kitchen Deluxe controller works in conjunction with the Bathroom Deluxe controller, letting you know via the speaker in the kitchen when your bath is ready.

Digital controllers allow you to select the exact temperature of the hot water at the tap within the controller temperature range.

Product Details

Benefits of a controller:

  • Safety, especially if you have young children, the hot water can be preset to a child-safe level

  • No need to mix hot and cold water, this reduces the affect of temperature spiking when another tap in the building is turned on

  • You use your continuous flow unit more efficiently as less gas is required to heat water to 40 °C (typical shower temperature) than at 55 °C (default temperature without controllers)

  • Allow diagnosis of problems (such as gas supply disruption) in the unlikely event or a fault, or for a maintenance review when the INFINITY is serviced.

Extended warranty
Rinnai INFINITY installations with a Rinnai controller receive an extended warraty.

IP rating

Rinnai controllers are not IP rated. The controllers are low voltage (12 V DC) from the Rinnai INFINITY via a cable to the controller. Rinnai does not recommend placing a controller where they will get wet from a shower head, tap or water fixture. They are water resistant, not water proof.

Suitable for these products

Installations with a Rinnai INFINITY continuous flow gas hot water heater installed, refer compatible water heater models in the 'Tech Specs' section. Each remote controller can be individually programmed, however the water heater can only deliver one set temperature at any time.

Rinnai water controllers cannot be used with Rinnai INFINITY units connected to solar systems, when a Rinnai iHeat is installed, or in a ring main system using N-Series models.

Controllers are water resistant, however, durability is improved when positioned outside the shower recess. All deluxe water controllers must be installed at least 400 mm above the highest part of a sink, basin, or bath.

Controller configurations
A maximum of four water controllers (three for the N-Series, A28i, HD49kWi) can be fitted. Any combination of the deluxe, compact, and wireless* controllers can be used within the following parameters:

• Only ONE master can be installed. This can be a Kitchen Deluxe, Compact, or Wireless* Controller.
• Up to two Bathroom Deluxe Controllers can be installed.
• Fourth controller in any installation must be a Compact or Wireless* Controller. 

* The wireless controller is discontinued


If your Rinnai INFINITY controller starts with MC91, you can upgrade it with one of these current controllers, but it would be wise to check what model of you have.

If your controller is one of these models below, unfortunately it is obsolete with no upgrade available due to the age of your Rinnai INFINITY unit.

  • MC-31-A
  • BC-31-A
  • MC-33-1A
  • BC-45-2A
  • BSC-45-1A

Consider upgrading your Rinnai INFINITY and your controller at the same time.
