Er03 You have set-up a cooling application that

requires a reference room thermostat to be appointed.

Er05 Communication lost to Radio Module. Please check that the cable is properly connected in the Radio

Er06 Communication lost to room thermostat. Identify the room thermostat by looking at the ashing

Er07 Communication lost to Slave Controller. If wireless, check Radio Module connection to Danfoss

Er08 Communication lost from Slave to Master

Controller.

Er10 Communication lost to Repeater. Check that the repeater is plugged into outlet / has not been

Er11 Communication lost to Expansion Module. Check that Expansion Module is slidded fully into place.

Er12 Actuator defective.

The defective actuator output is ashing.

Er14 A Danfoss Icon™ Master Conroller cannot

be included as (become) a Slave Controller because one or more room thermostats, repeaters or Danfoss Icon™ Master Controller 24V have allready been included.

Please go to the thermostat in the desired reference room and enter the thermostat installer menu. Set thermostat to ON in ME.6 “reference room thermostat”.

Er16 This application requires a specic actuator

output to be available.

Er17 External PT1000 sensor not tted, or defective. Check sensor and replace if necessary

You have already assigned this output to a room thermostat, or the output has not yet had an actuator tted. Please uninstall RT from TWA, it must be available to the application chosen (or t actuator – if this was not yet done).

Note! Remember to ensure that the Master Controller is connected due to risk of electric shock.
