411 to 416 Description: Faulty Room Sensor
Cause: The ATAG One Zone or Cubes for the specified zone are incorrectly set or faulty. The zones are highlighted via
the 3
rd
number of the fault code i.e., 411 is zone 1, 412 is zone 2 and so on up to zone 6, 416. Room Sensors are
either ATAG One Zone controllers or Cubes only. No other 3rd party thermostat will act as a 'room sensor' into the
boiler.
1. The Zone assignment must be correct on the ATAG control, so One Zone or Cube zone assignment must
correspond to the zone parameter in question. i.e., zone 1 thermostat = zone 1 parameter 4.2.1, zone 2
thermostat = 5.2.1. The full 6 zones are shown below.
• 4.2.1 for zone 1.
• 5.2.1 for zone 2.
• 6.2.1 for zone 3.
• 14.2.1 for zone 4.
• 15.2.1 for zone 5.
• 16.2.1 for zone 6
2. Check PCB settings for configuration issue. Where a zone parameter has been configured incorrectly for the
heating control equipment used.
3. Check the Thermoregulation is set correctly in the technical area using the above parameters. This
parameter can be set to 2 or 4 if One Zone or Cube is fitted.
4. Other 3rd party thermostats must have this parameter set to either 0, on/off fixed flow temp, or 3 for
weather comp with on/off. If 3 is selected an outside sensor must be fitted as well.
420 Description: ATAG zone supply overload.
Cause: When using ATAG Zone managers or pump modules, A "BUS supply overload" error may appear when three
or more devices supplying power to the BUS are connected to the system.
1. To rectify this error, microswitch 1 on the PCB of one of the Zone Managers, or pump modules must be
switched from ON to OFF.
