WATER CONTROLLER INSTALLATION

GENERAL INFORMATION

Other manufacturers water controllers are NOT compatible with Rinnai water heaters. Water controllers MUST NOT be used with any Solar Boost water heater. Rinnai water controllers brought in from other countries are not compatible with Rinnai appliances sold in Australia.

Regardless of water controller installation, all Rinnai water heaters must only be installed by an Authorised person.

Water controllers, transceivers and water heaters DO NOT contain user serviceable parts and must ONLY be serviced and repaired by an authorised person.

Master / Sub Water Controllers & Associated Temperatures

Only one MC model water controller can be designated as the 'Master' water controller. This water controller is

kitchen applications. Temperatures higher than 55°C are possible but usually unnecessary and will result in higher gas use and increase the risk of burns.

Some additional conditions regarding Master Controller maximum temperatures apply when a wireless water controller is used as the 'Master' water controller.

(i) Temperatures of 55°C or higher can only be selected on the controller designated as the 'Master' water

controller if the transceiver 'Max Temp' is also programmed to 55°C or higher.

(ii) The temperature of hot water delivered is always limited to the maximum temperature programmed into the

water heater itself. For example, if the transceiver maximum temperature is programmed to 55°C and the water heater is limited to 50°C, the maximum temperature that the water heater will deliver is 50°C. In this case 55°C will be displayed on the wireless Master Controller until a tap is opened after which the display will revert to 50°C.

The water heater maximum temperature cannot be adjusted by the user. These adjustments can

The remaining water controllers are designated 'sub' controllers and are for use in bathrooms, toilets and laundries. The temperature limit for all 'Sub' controllers is always 50°C to minimise the risk of burns in these areas.

Location

NOTE

• DO NOT install water controllers near a heat source, such as a cook top, stove or oven. Heat,

steam, smoke and hot oil may cause damage.

• DO NOT install water controllers outdoors unless protection from water / dust ingress and

sunlight are provided.

• The water controller set as the MASTER water controller MUST NOT be installed in a

bathroom.

• DO NOT install water controllers in direct sunlight.

• DO NOT install water controllers against a metal wall unless the wall is earthed in accordance

• Water controllers MUST NOT be installed where chemicals such as benzene, alcohol,

turpentine, hydrogen sulphide, ammonia, chlorine or other similar chemicals are in use.

The Water controller is a water resistant device, however excessive exposure to water may result in damage to the water controller. Durability is improved when positioned outside the shower recess.

• AVOID direct exposure to water or steam as these conditions may cause a malfunction.

•

MUST BE installed at least 400 mm above the highest part of a sink, basin or bath.

• When cleaning your water controller use ONLY a damp cloth and a mild detergent.

For water controller dimensions refer to "Table 4. Appliance Dimensions - B Series & Universal Water Controller" on page 34.

Communication Cables

Wired water controllers operate at an extra low voltage (12 Volts DC) which is supplied from the water heater, a 10 metre long communications cable is supplied for connection to the water heater. Rinnai supplied communication cables may be used.

Optional longer per metre communication cabling Part No. 92078609 is available from Rinnai.

The per metre communication cable does not come supplied with spade connectors, spade connectors are available from your local electrical component retailer.

Joining Communication Cables (REU-A / REU-AM)

so that there are only two sets of spade connectors (4 spade connectors in total) to be terminated (spade connectors are available from your local electrical component retailer).

Connecting Communication Cable(s) With 'Ezi connect' (REU-A / REU-AM)

CAUTION

DO NOT attempt to connect cables to the 'Ezi connect' cable connector at the water heater

components may occur.

1. Isolate the electric power supply by switching

plug of the water heater from the electric power socket.

2. Remove the retaining screw A of the 'Ezi

connect' cable connector at the base of the appliance.

3. Swing the 'Ezi connect' cable connector door

open and thread the cable through the weather seal of the cable access hole B in the direction

the sheath of the cable can be secured with cable clamp C.

4. Loosen screw terminals D & E and connect

the cable spade connectors to these terminals and re-tighten.

Polarity is not important, either wire colour can be connected to either terminal.

5. Return the 'Ezi connect' cable connector to

the original position taking care not to damage cable wires in the process and replace the retaining screw A.

Connecting Communication Cables to Mini-Plug (REU-E & REU-VCM)

Installation MUST

DO NOT attempt to connect water controller cables to the mini-plug when it is plugged into the

components may occur.

Water controllers are connected to the PCB via a dedicated pre-wired mini-plug (supplied).

Use the supplied electrical cable connectors to terminate the water controller wires to those of the mini-plug. The existing spade connectors of the communication cables will need to be removed prior to termination. Controllers are not polarity sensitive, however to avoid confusion it is recommended that like coloured wires be terminated together.

2. Remove the front cover of the appliance.

3. Insert the mini-plug and the connected

7. Proceed with the water controller

installation and connect the communication cables to controllers.

UNIVERSAL WATER CONTROLLER (MC-601Q) INSTALLATION

1. Determine the most suitable position, refer "Location" on page 25.

2. Mark and drill 3 holes (mounting and cable access) refer to page 34 for water controller dimensions.

3. When running cable through the access hole ensure the connector end of the cable is located nearest to the

water controller (Fig. 1).

4. Carefully remove the cover plates from the water controller, using a screw driver (Fig. 2).

5. Connect the cable to the water controller. Feed any excess cable lengths into the wall cavity to avoid the

pinching of cables between the wall and the water controller.
