 Operation

Manual mode

There are two temperature setpoint levels at our disposal. In manual mode chosen setpoint temperature level is maintained permanently until user changes operation mode or  set a different temperature for each level.
– Comfort Mode – in this mode, the thermostat is to maintain a constant day temperature. When the temperature is set manually, e.g. 23°C, the thermostat maintains it until  user switches to another operating mode or set a different temperature, e.g. 21°C.
– Economic Mode – in this mode, the thermostat is to maintain the reduced (night) temperature. When the temperature is set manually, e.g. 17°C, the thermostat maintains it until user switches to another mode or set a different temperature, e.g. 19°C.

Comfort mode

In the comfort temperature mode, the thermostat is to maintain a constant day temperature. The comfort temperature level is indicated by sun icon.
To set the comfort temperature, see the steps below:

Press any button to highlight the display.| Press button to enter comfort temperature mode.
The sun icon should be visible on the display.
Using or buttons set new comfort temperature value.| Confirm by button or wait until the thermostat will approve your choice itself and display the main screen.
The thermostat will return to the main screen and display the actual room temperature.

Economic mode

In the economic temperature mode, the thermostat is to maintain a reduced (night) temperature. This is to ensure a more economical operation of the heating system when,  for example, you are away from home. The economic temperature level is indicated by the moon icon. To set the economic (night) temperature, see the steps below:

Press any button to highlight the display.| Press button to enter economic temperature mode.
The moon icon should be visible on the display.
Using or buttons set new economic temperature value.| Confirm by button or wait until the thermostat will approve your choice itself and display the main screen.
The thermostat will return to the main screen and display the actual room temperature.

AUTO mode – two schedule types

– AUTO Mode – In the automatic mode, the thermostat maintains the set temperature according to the schedule selected by the user. You can choose from 2 types of schedule to manage the temperature during the week.

First type schedule

First type schedule mode is represented by timeline – 24 hours of a day. Empty „boxes” means hours where Economic (Moon) setpoint temperature will be maintained, black  „boxes” means hours where Comfort (Sun) setpoint temperature will be maintained.
There are three different configurations in a schedule type 1:

• Two different programs (timelines), separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday)
• Individual programs (timelines) for each day of the week
• Same program (timeline) for the whole week

Second type schedule

Schedule type 2 enables the programming of 6 time intervals per day, with precision up to 10 minutes. Each of the 6 time intervals allows you to set a different temperature  (schedule type 1 is limited to switching between two setpoint temperatures (SUN/MOON) at full hours time periods).
When creating a schedule type 2, you must define time and temperature setpoint (thermostat will start to maintain given setpoint temperature from given time setting). There are three different schedule configurations:

• Two different programs, separate program for working days (Monday to Friday) and separate program for weekends (Saturday to Sunday)
• Individual programs for each day of the week
• Same program for the whole week

Schedule of the second type example

TIME INTERVAL| DAYS OF THE WEEK (1 TO 5) MON-FRI| DAYS OF THE WEEK (6 TO 7) SAT-SUN
---|---|---
P1| Time 6:00 Temp. setpoint 21 ° C| Time 6:00 Temp. setpoint 18°C
P2| Time 8:00 Temp. setpoint 14°C| Time 8:00 Temp. setpoint 20°C
P3| Time 11:00 Temp. setpoint 21°C| Time 11:00 Temp. setpoint 22°C
P4| Time 13:00 Temp. setpoint 14°C| Time 11:00 Temp. setpoint 22°C
P5| Time 16:00 Temp. setpoint 21°C| Time 16:00 Temp. setpoint 18°C

Pairing with the E901RX receiver

PLEASE NOTE!
E901RF thermostat is already paired with the receiver!
In order to pair the devices correctly, you must first prepare the receiver for synchronization!

If you want to re-pair the devices with each other,  make sure that the receiver is disconnected from  the power supply and the switches on it are in the  AUTO and ON positions. Then connect the receiver to the power supply and wait for the  green diode to glow continuously.| Move the left switch to the OFF position and  back to the ON position with a quick motion.| The green LED will start blinking to confirm that the receiver has entered the pairing mode.

Press and hold button for 5 seconds.| Use button to select SYNC parameter.
Confirm by button.| Using or buttons choose YES and start the pairing process on a new frequency by pressing the button.
The thermostat started to send a signal to find the receiver (the symbol of the blinking antenna) and started the countdown with the number 10 (min).  The pairing process may take up to 10 minutes.| When the green diode on the receiver lights up continuously, the devices have been paired on a new frequency.
The thermostat will display the message „good”, which means that the devices are successfully paired with each other.| The thermostat will return to the main screen.

WARNING! If the green diode on the receiver has not stopped blinking after 10 minutes, repeat the pairing process taking into account the distance between devices, obstacles and interference.

Transmission test

It is important to place the receiver and transmitter in places where nothing is interfering with the radio signal. The range of communication between the transmitter and the  receiver in an open area is up to 60m. The radio transmission is influenced by many factors that can shorten the working distance, such as thick walls, drywall covered with  aluminum foil, metal objects such as cabinets, general radio interference, etc. However, the range is sufficient for most domestic applications. It is recommended that the radio transmission between devices has to be tested before mounting the thermostat to the wall. The test can be performed by changing the set temperature, i.e. by activating or deactivating the heating.

Check that the thermostat is not sending a signal to heat.
Press any button to highlight the display.| Press button to enter comfort temperature mode.
The sun icon should be visible on the display.
Using or buttons set new comfort temperature value.| Confirm by button or wait until the thermostat will approve your choice itself and display the main screen.
The thermostat started sending a heating signal when the screen went blank, which was signaled by the antenna symbol.

The flame icon will start to animate, which means that the thermostat is sending a signal to heat.| Check that the orange LED on the receiver is on. If so, it means that the communication between the devices is correct.
Set the temperature setpoint a few degrees lower than the room temperature by repeating steps 1 to 5. Wait a few seconds. The flames icon should stop animating…| …and the orange LED on the receiver should go out.

Please note:
If the orange LED does not turn on / off as indicated by the transmitter flame icon, try moving the transmitter closer to the receiver and repeat all steps from the beginning.
If it still doesn’t work, try the pairing process again.
