Problem Solution

actuator output to be available.
You have already assigned this output to a room
thermostat, or the output has not yet had an
actuator fitted. Please uninstall RT from TWA, it
must be available to the application chosen (or fit
actuator – if this was not yet done).
Er17 External PT1000 sensor not fitted, or
defective.
Check sensor and replace if necessary
NOTE! Remember to ensure that the Master Control-
ler is connected due to risk of electric shock.
14.5. Frequently asked questions on Danfoss Icon™ section:
• How do I activate pairing mode Danfoss Icon™ Zigbee Module?
Pairing mode is activated by short pressing the button. The GREEN LED must be rapidly flash-
ing while the Danfoss Icon™ Zigbee Module is searching for the Danfoss Ally™ Gateway. If the
green LED is not rapidly flashing, then factory reset should be performed:
1. Remove the LAN cable from the Danfoss Icon™ Zigbee Module
2. Press and hold the button while connecting the LAN cable again
3. Hold the button until constant red LED and release the button.
Short press the button should then make green LED rapidly flashing.
Please note that the Danfoss Ally™ Gateway might need up to 60 seconds to discover the
device.
• Why is the LED is flashing red on my Danfoss Zigbee repeater?
Danfoss Zigbee repeater is designed to extend the wireless range from the Danfoss Ally™ Gate-
way to the Danfoss Ally™ Radiator thermostats or Danfoss Icon Zigbee module. If the Danfoss
Zigbee repeater is placed in a location where it is not active – meaning none of the devices are
communicating through the repeater then the LED will start flashing to indicate it is not being
used. Try moving the repeater to a different location.
