Also, any changes made to the Wireless Temperature Sensor’s settings won't take effect until the radio link is reconnected.
How to manually control the Wireless Receiver without a radio link.
When the Wireless Receiver hasn’t gotten a room temperature update from the Wireless Temperature Sensor, it will continue to operate with the last settings received from the Wireless Temperature Sensor until the link is repaired, or you make a manual change.
When the radio connection is lost, you can manually switch heating and hot water on or off directly on the Wireless Receiver.
When the connection to the Wireless Temperature Sensor is lost, the connection LED on the Wireless Receiver will blink.
Check the error LED.
If the error LED is blinking the same way as the connection LED, it means that the device will keep the last heating temperature set before the connection was lost.
The heating and hot water LEDs show the last recorded state before the radio link was interrupted and can either be solid on or off.
