4.1. Setting mode
Press and hold OK and “” buttons for approximately 3 seconds to enter the setting mode.
Configure the thermostat in the following way: choose a required parameter with “”, “”
buttons, use OK button to enable the introduction of changes and change the value using “”,
“”, then confirm the modified value with OK button. The following parameters may be
changed:
1. Hysteresis — H
It is a difference between current and preset temperature being allowed by
the thermostat. It determines the accuracy of room temperature control. Euroster Q1E
enables selecting the following values of hysteresis: 0.2°C/0.5°C/1°C/2°C or 5°C.
The sketch depicts the effect of hysteresis
2. Sensor calibration — C
It is a value added to or subtracted from the measured temperature value. It enables
correction of the displayed temperature. Calibration range: -5°C... +5°C with 0.2°C step
of the change.
3. Operation mode — t
It enables to choose the thermostat operation in heating (“ ” icon) or cooling (“ ” icon)
mode.
4. Selection of sensor — S
This option enables to select a temperature sensor to cooperate with the thermostat.
There are three operation modes available:
“S 0” — the thermostat measures and maintains the temperature based only on internal
sensor operation
“S 1” — the thermostat measures and maintains the temperature based only on external
sensor (the one with cable) operation
“S 2” — the thermostat measures the temperature of both sensors; maintains
the temperature of an internal sensor, and the external sensor acts as a temperature limit.
5. Floor temperature limit value (active only in S2 mode) — L
This parameter enables setting the maximum safe floor temperature. When this
temperature is reached, the relay is switched off.

5. THERMOSTAT OPERATION
5.1. Setting temperature
Use “”, “” buttons to set the desired temperature value. Pressing one of the buttons for the
first time will make the current temperature preset blink and repeating the activity will cause
the temperature value decrease or increase adequately with 0.2°C step of the change.
The longer the button remains pressed, the quicker the values change. Confirm
the temperature change with OK or wait until the set value stops blinking and is stored.
5.2. Programming and program canceling mode
One or two temperatures entered by the user may be stored daily in a program. The preset
values are stored with an accuracy of one minute. When operating with a program, the
thermostat switches the stored temperatures regularly at their setting times.
Enter the programming mode by pressing OK for approximately one second, PROG ON sign
appears on the display, then enter the temperatures at the adequate times. This mode is quit
after:
•entering two temperature values. The preset temperatures with their setting times are
stored as a program. The displayed PROG sign signals the end of programming cycle.
The program is then implemented regularly on all days of the week.
•a lapse of 24 hours. If one temperature value is entered, the thermostat maintains this
temperature. If no temperature is entered, the programming mode is canceled.
•holding OK for 1 second twice. Pressing it for the first time enables to turn on
programming mode again and pressing it for the second time enables to leave
the programming mode and erase the previous program. Leaving the programming
mode is signaled by displaying PROG OFF sign for approximately one second.
Example:
Switch to the programming mode (PROG ON). First temperature is set to 8.00 am, e.g. 21°C,
the second one is set to 4.00 pm, e.g. 19°C. Entering the second temperature completes
programming. The thermostat quits programming mode (PROG) automatically. The next day
the thermostat will maintain the temperature of 21°C from 8.00 am to 4.00 pm and 19°C from
4.00 pm to 8.00 am.
5.3. Temporary change of temperature
During the thermostat operation with the stored program, it is possible to introduce changes
of temperature using “” and “” buttons. However, the changed value will be valid only until
the next hour stored in the program. For the time of temporary operation with changed
temperature icon is displayed.
If you want to restore operation with the stored program, use “” “” buttons to set
temperature at which icon disappears.
5.4. Operation with two temperature sensors
The function of floor temperature limitation is active when two sensors are connected and S2
mode is selected. If the preset temperature is reached at any sensor, the receiver is turned off.
The floor temperature limit control operates with fixed hysteresis of 5°C. The device is turned

on again when the temperature drop reaches the hysteresis value. Overview of the current
temperature of the floor sensor is possible in test mode.
5.5. Turning the thermostat off
In order to switch the thermostat off, hold “”, “” buttons for 3 seconds. OFF sign is
displayed. The relay is turned off.
Hold the same buttons for 3 seconds again in order to switch the thermostat on.
In case of loss of power, the program is stored for approximately 10 hours, and the parameters
of setting mode are not deleted.
5.6. Indication of sensor damage
According to the type of damage there is a "Sh" or "OP" sign displayed adequately for shortage
and opening (break) of the sensor. If the floor sensor is damaged, then blinking “ ” icon is
displayed additionally.
6. TEST MODE
Test mode enables checking the main parameters of the thermostat. In order to enter the test
mode press and hold OK and “” buttons for approximately 3 seconds. Choose the desired
test with “”, “” buttons and in case of testing a relay use OK button to change its status.
