| B1 | IP code high setting | 00-FF | 0 |
| B2 | IP code low setting | 01-FF | 1 |
| B3 | Thermostat and receiver paired | Display”55″ means IP match successfully. (When receiver is power-on, and orange LED is on ,press thermostat | 0 |
| B4 | Sensor state | N1:single built-in sensor N3:both built-in sensor and external sensor. | N1 |
| B05 | Minute interval of RF transmission | 0-30 minutes | 20 min. |
| B06 | Second interval of RF transmission | 3-30 seconds(B5=0 IS availd) | 30 s |
When the setting value of B5 and B6 in the advanced option is less than or equal to 20 minutes, it is recommended to use the USB adapter to supply power. If the battery is used for power supply, the battery life will be greatly shortened.
Description of hysteresis: The factory initial high temperature protection is set to 45℃, and the high temperature protection hysteresis is set to 2. When the external sensor detects that the temperature rises above 45℃, the relay will stop output and the thermostat will send out a high temperature protection alarm; When the sensor detects that the temperature drops below 43°C, the relay will re-output and the alarm will be cancelled. (This function is valid when the relay has output) Please select the internal and external temperature sensor working mode correctly. If the selection is wrong or the sensor is faulty (damaged), the display interface will display “E1” or “E2”, and the thermostat will stop heating until the fault is eliminated.
Description of thermostat data communication:
- Under normal working conditions, communicate with the receiver every 20 minutes.
- Press the switch button to communicate with the receiver once.
- When the output status is switched, it will communicate with the receiver once.
: Always on when wireless communication is normal, and flashing when wireless communication is abnormal.
Receiver Indicator Light
Power indicator (green): Always on after power-on, and off: green light on for 1 second and off for 1 second.
RF signal indicator (orange): always on within 10 seconds of power-on (at this time, the IP address of the thermostat can be sent to the receiver to complete the pairing: refer to the thermostat and receiver pairing options in the advanced options), the pairing is successful After that, the signal light will be off; or if there is no pairing action within 10 seconds, the light will also be automatically turned off; during normal work, the light will flash when a wireless signal is received.
Load/fault indicator (red): In normal operation, the load output is turned on, the light is on, and the load output is off, and the light is off; when there is a fault, it flashes to alarm, and the fault indication is as follows:
- The thermostat and the receiver are not paired: flashes 2 times (quick flashes), with an interval of 2 seconds off
- Loss of wireless signal (no data communication in 1 hour): flashes 3 times (quick flashes), with an interval of 2 seconds off
- External sensor alarm: flashes 4 times (fast flashes), with an interval of 2 seconds off
Note: Fault 3 is only valid when the sensor type is selected as N3 in the advanced options of the thermostat.
WIFI signal indicator (blue): When WIFI data is received, it will flash once; continuous fast flashing means it is in WIFI EZ network configuration mode; continuous slow flashing means it is in WIFI AP network configuration mode; it will be often after successful network configuration On for 2 seconds; when the WIFI is abnormal, it will flash twice quickly with an interval of 2 seconds off.
