DANGER

Operating instructions Rinnai E-Series

The Rinnai E boiler is a room sealed, condensing

and modulating central heating boiler with an

integrated hot water facility.

The boiler is provided with a integrated control

system. Because an outdoor sensor is connected

to the boiler, the boiler works weather dependantly.

This means that the boiler control measures the

outside temperature and ow temperature. With

this data the boiler calculates the optimal ow

temperature for the installation.

When the boiler is connected to an RS100 room

thermostat information can be retrieved from the

boiler. For more information about the Rinnai

thermostats. Please refer to the user manuals.

On the bottom left side of the front panel there is a

small door. Through the transparent panel you can

see the boiler status on the display. After opening

this door you will nd the function buttons.

On the following pages you will nd the explanation

of the function buttons and display messages.

Description of the boiler

RS100

Operating instructions Rinnai E-Series

Explanation of the function buttons

Only qualied personel who are trained for

these boilers are permitted to make alterations

in the controller to chronolize the boiler to the

installation.

1. Display.

See following pages for further information.

2. ON-OFF Switch (Placed separately next to

the boiler). This switch turns the power supply

to the boiler on or off.

3. Central Heating program button.

Switching the Central Heating on or off (Led

on/off);

4. Hot Water program button.

Switching the Domestic Hot Water (DHW)

facility on or off (Led on/off);

5. Pump program button.

When the pump program LED is ON, the pump

is switched into a continuous circulation mode.

When the pump mode is switched OFF, LED is

off the pump is control by the boiler processor.

In most situations it is best to leave the pump

mode OFF and let the boiler control cycle the

pump as needed.

During freezing temperatures it is possible (when

there is no outside sensor connected), to manually

place the circulation pump in constant circulation

mode, thus reducing the chance of freezing pipes

(garage, attic or other cold spaces / rooms) which

are sensitive to frost.

When the pump is switched

on continuously it can lead to

undesired heating up of the

central heating system during

the summer.

Technical

The second way is a technical read out. In normal

situations the following will be shown:

• on the left the status in which the boiler is active

(see bottom of this page);

• on the right the supply temperature in °F;

• the water pressure in the installation in PSI.

When a message (E or BL code) is necessary this

will be shown instead of the technical read out.

To switch over from the Good-state to the

Technical read out (and vice versa):

- Press 5 sec. on the STEP-button.
