3. E901RXWIFI receiver
3.1 Receiver’s switches description
E901TXWIFI thermostat communicates bi-directionally with the E901RXWIFI receiver on the 868Mz frequency. The set is factory paired and prepared
for work. In addition, the receiver has a built-in 2.4Ghz Wi-Fi and BLE (Bluetooth Low Energy) module. So that the thermostat can be controlled with
mobile application, place the receiver within the 2.4GHz Wi-Fi network. The receiver should be powered with 230VAC, and
the maximum load of the receiver is 16A. It is forbidden to install the device in places exposed to water and steam condensation
water. The receiver can operate in two dierent modes - AUTO (automatic) and MANUAL (manual).To select a specic mode, use the switches
on the front of the receiver.
Thermostat (transmitter) will communicate with receiver only when both are paired together and receiver’s switches are set to ON and AUTO position.
LEFT SWITCH
1. ON - receiver ON
2. OFF - receiver OFF
RIGHT SWITCH

MANUAL - Receiver works in manual mode
(receiver operation state depends on the position of
the left switch)
4. AUTO - Receiver works in AUTO mode
(according to the thermostat’s commands)

DESCRIPTION
The red ashes
The red LED diode ashes - receiver and thermostat are prepared for installation in the app.
LED always ashes red:
- immediately after connecting the receiver to the power supply, if the thermostat is not
added to the app
- after running the parameter“APP”-> YES (installer parameters)
- after removing thermostat from the app (device automatically entered pairing mode)
The red LED lights up
The red LED diode is steady - E901 WIFI has not been installed in the app and it is working
in Oine mode. It means also app pairing mode timed out (pairing with app must be done
within 10 minutes after enabling pairing mode).
The green LED lights up The receiver is connected to a router, that does not have access to the Internet (works in
oine mode).
The green ashes The receiver lost communication with the router (router turned o).
The blue LED lights up The receiver is connected to a router with Internet access (works in online mode).
The blue ashes
Odbiornik był sparowany, ale stracił łączność z regulatorem z powodu braku zasięgu lub
wyczerpania baterii w regulatorze. Niebieska dioda na odbiorniku zaczyna migać po ok. 15
minutach, gdy nie otrzyma sygnału z regulatora.
The
orange LED lights up The receiver in AUTO (automatic) mode received a heating / cooling signal from
regulator or the receiver has been started in manual mode (left switch ON, right switch MANUAL).
The
orange is o The receiver didn’t get a heating / cooling signal from the thermostat.
The
orange ashes
The receiver is in the pairing mode and is looking for a signal from the thermostat (then you need to run
the parameter SYNC on the thermostat).The receiver was paired, but lost communication with the ther-
mostat due to lack of range or exhaustion of the battery in the thermostat.The orange LED on the receiver
starts flashing after approx. 15 minutes, when it does not receive a signal from the thermostat.
The
pink LED lights up The update process has started.To increase the chance of successful update - immediately after
the pink LED appears, click any button on the thermostat to turn on the display backlight.
