Normal State (the steady connection between Sender and Recipient)： When the RF signal is transmitting, Green LED is flashing ONCE in every 30 minutes; Heating equipment connected, Red Led is ON

Integrate Panel with Receiver

How to Learn

Recipient(RECEIVER)：
Press and hold Learn button for some secs, Green LED will keep flashing. When the Learn is done and successful, Red LED is on and Green Led stop flashing.

Sender(HTW-91-WT410 Controlling Panel)：
At the state of switching off, press and hold button for some secs to enter into Learn. In this case, the display of room temperature is “rE”; after that, press button quickly, Learn is matching. If Learn is successful, the display of Room Temperature should be “OH”; if not, the display is “Er”, please Learn again.
