Compact Controller (MC601A)

The Rinnai Compact Controller is our smallest, most affordable model.

Digital controllers allow you to select the exact temperature of the hot water at the tap within the controller temperature range. This has a number of benefits:

  • Safety, especially if you have young children, the hot water can be pre-set 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).
  • Allows diagnosis of problems (such as gas supply disruption) in the unilikely event or a fault, or for a maintenance review when the INFINITY is serviced

Extended warranty

Rinnai INFINITY installations, when a controller is connected receive an extra two years on the INFINITY warranty.

Suitable for
Installations with a Rinnai INFINITY continuous flow gas hot water heater installed, refer compatible water heater models below.

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.
