Frequently Asked Questions - i40R Atag

How do I change the central heating temperature on my Atag i40R?

Press OK on the home screen, select Complete Menu, then CH Settings, then CH Setpoint Temp. Use the selector wheel to adjust the temperature and press OK to confirm.

How do I set the DHW temperature on the i40R?

From the home screen, press OK, go to Complete Menu, then DHW Settings, then DHW Comfort Setpoint Temp. Adjust with the selector wheel and confirm with OK.

What do error codes on the i40R display mean?

Error codes are two types: blocking (temporary, e.g., 1P4) and error (requires reset, e.g., 101 overheat). Press the Reset button to clear error codes. Refer to the manual's error list for specific meanings.

How do I reset the boiler after an error?

Press the Reset button located on the boiler control panel. If the error persists, check for underlying issues like low water pressure or a blocked flue.

What should I do if the water pressure is too low?

If pressure is below 0.8 bar, refill the system using the filling loop (for iC boilers) or contact your installer (for iR open vent systems). After refilling, run the air purge program (approx. 7 minutes).

How do I activate continuous pump operation for frost protection?

Go to Complete Menu > CH Settings > Pump continuous running and set to Enable. The pump will run continuously to prevent freezing.

What type of maintenance does the i40R require?

Arrange an annual service with a qualified engineer. Clean the exterior with a non-aggressive cleaning agent. The Benchmark Checklist should be updated after each service.

Can I use chemicals or inhibitors in the heating system?

Only add chemicals like frost inhibitors on the advice of your installer. Use only potable water for filling. Improper additives can cause corrosion and void warranty.

Where can I find the warranty card and how to register?

The warranty card is supplied with the boiler. Fill it out completely and send it back to ATAG Heating Technology Ltd. Registration ensures full service support.

How do I access boiler information like flow temperature or pressure?

Press and hold BACK and OK for 7 seconds, enter code 007, then select Complete Menu. Navigate to 8 Service Parameters to view values like CH Flow Set T or pressure.

3 Boiler description

The ATAG i-Range boiler is a closed, condensing and modulating heating boiler which meets the European standard (CE).

A declaration of conformity can be obtained from the manufacturer.

The efficiency of the boiler is very high and the radiation convection and standby losses very low. The emission of noxious substances is far below the fixed standards so the boiler is >88% Efficient SEDBUK 2009 rated.

4 Screen and functions

The boiler is equipped with a door at the front. For opening the door just pull at the door handle.

After opening the flap you will find on the inside of the flap a brief overview of the meaning of all the buttons and icons. These are described hereafter.

If the (T1) flow sensor registers a temperature of 5° C or below in the boiler, the boiler will fire up. The boiler keeps on firing until the temperature reaches 10° C (measured on the flow sensor) and the boiler switches off again.

5 Filling the heating system

Information on the water pressure (only iC and iS)

Information of the actual water pressure:

The controller Home screen shows OK. The actual water pressure is always visible.

Water pressure is too low (<0.8 bar):

Power is reduced by 20%. The installation should be refilled.

Water pressure is too low (<0.5 bar):

The boiler is taken out of operation. The installation should be refilled.

Air purge program:

After the installation has been refilled and if the pressure was below 0.5 bar the air purge program will start. This will last for approximately 7 minutes.

Water pressure is too high (> 3.0 bar):

The boiler is taken out of operation.

The installation pressure should be reduced by draining water from the heating system.

The central heating installation needs to be filled with potable water according to the requirements in chapter 9.3 'Water quality' in the Installation manual. For filling or topping up the installation use the filling loop according to the following procedure (see figure 1).

Filling procedure

Combi boiler (iC-Range):

The iC-Range boiler is provided with a filling loop. Connect the filling loop between cold water connection (1) and CH connection (2)

• Open slowly the valves (A and B) of the filling loop;
• Read the water pressure from the pressure gauge under the boiler or from the display according to the procedure described above and wait until the pressure reaches between 1.0 and 1.2 bar;
• Close both valves (A and B) of the filling loop. Always disconnect the filling loop and close the valves with the cap nut (3).

System boiler (iS-Range)

The heating system connected to the iS-Range boiler is provided with a filling loop.

Connect the filling loop between cold water tap and the connection on the heating system

• Open slowly the valves of the filling loop
• Read the water pressure from the pressure gauge under the boiler or from the display according to the procedure described above and wait until the pressure reaches 1.2 bar.

- Close both valves of the filling loop

Always disconnect the filling loop.

Figure 1

Regular boiler (iR-Range)

This boiler is part of an 'Open Vent' heating system. The system is not pressurized, but is filled automatically by a filling system in the loft.

If there is a problem with this system, please contact your installer.

When the heating system is filled and after a power interruption the boiler will be reset and starts with a air purge program. The automatic air purge program will take approx. 7 minutes and will be followed by the home screen if the water pressure is above 0.8 bar (pressure reading for iC & iS boilers only).

A detected failure is indicated on the screen in blocking or error messages.

- Blocking code

A blocking code is a temporary error that can be automatically corrected by the boiler.

- Error code

A error code requires the error to be reset and/or corrected for the boiler to go back into a normal operating mode. A "Press the Reset button" message appears on the screen.

An overview of the most common blocking and error codes are listed below.

101 Overheat
102 Pressure Sensor Error
104 Flow Check Failed
108 Pressure < Pmin (< 0.5 bar), Filling needed
1P4 Pressure < Pmin (0.5 - 0.8 bar), Filling needed
109 Pressure > Pmax
110 Send Probe Damaged
112 Return Probe Damaged
114 Outdoor Sensor Damaged
141 CH Flow Switch open
201 DHW Probe Damaged (Combi)
203 Tank Probe Damaged (Solo)
303 PCB Fault
304 Too many resets
501 No flame detected
612 Fan error (fan does not start up)
