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% E󰀩cient 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 ap you will nd on the inside of the ap a brief overview of the meaning
of all the buttons and icons. These are described hereafter.
The Control unit has a 'sleep mode' if no key is operated within a certain time.
Activation occurs by any key operation.
Explanation of the buttons

Boiler frost protection
If the (T1) ow sensor registers a temperature of 5°C or below in the boiler, the boiler will
re up. The boiler keeps on ring until the temperature reaches 10°C (measured on the
ow sensor) and the boiler switches o󰀨 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 relled.
Water pressure is too low (<0.5 bar):
The boiler is taken out of operation. The installation should be
relled.
Air purge program:
After the installation has been relled 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 lled with potable water according to the
requirements in chapter 9.3 'Water quality' in the Installation manual. For lling or topping
up the installation use the lling loop according to the following procedure (see gure 1).

User manual ATAG iC, iS and iR-Range

Filling procedure
Combi boiler (iC-Range):
The iC-Range boiler is provided with a lling loop.
Connect the lling loop between cold water
connection (1) and CH connection (2)
- Open slowly the valves (A and B) of the lling
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 lling loop.
Always disconnect the lling 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 lling loop.
Connect the lling loop between cold water tap and
the connection on the heating system
- Open slowly the valves of the lling 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 lling loop
Always disconnect the lling loop.
Regular boiler (iR-Range)
This boiler is part of an 'Open Vent' heating system. The system is not pressurized, but is
lled automatically by a lling system in the loft.
If there is a problem with this system, please contact your installer.
When the heating system is lled 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).
