15. TEMPERATURE SHOWN IN DISPLAY  
SENSOR TYPE  
IN MENU STRUCTURE  
PARAMETER  
By default, the temperature shown on the display while  
in standby state is the setpoint. This may be altered with  
Parameter 12:”Temperature display”. It may also be changed  
by entering the local settings menu and holding the Center  
button for 2 seconds when “MODE” is displayed. You can  
choose between “SETT” and “RELT”. “SETT” is the Setpoint  
temperature and “RELT” is the real-time temperature.

21. BRIGHTNESS  
Using the menu choices “BR1” and “BR2”, the brightness  
of the display in Active and Standby state can be changed  
respectively. “BR1” and “BR2” are also included in the device as  
Parameter 13 (BR1) and Parameter 14 (BR2).  
16.KWH VALUE IN MENU  
The device supports power metering to give insight into the  
power consumption of the heating. The total consumption of  
the device can be seen in the system from the “kWh” menu  
option. The total consumption data can be reset by holding  
the Center button while in the kWh menu.  
22.DISPLAY ON/OFF (DON/DOFF)  
The thermostat has a display ON/OFF function which decides  
whether the display should turn completely off when in  
Standby. To enable/disable this function, hold the Left and  
Center buttons for 10 seconds. The display will show “DOFF”  
when the function is activated and “DON” when the function is  
disabled. When operating any button, the display will light up.  
17. SIZE OF LOAD  
In the “load” menu or from Parameter 26 (size of load), the  
load value can be set manually if the load is not directly  
connected to the thermostat. The size of load can be adjusted  
in 100W increments up to 9900W.  
23.DISPLAY ICONS  
ICON  
DESCRIPTION  
This icon will be displayed while the device is in Heat or  
ECO mode, and is currently heating.  
18.CHOICE OF SENSOR  
The thermostat has multiple sensors and sensor modes. This  
lets you configure the thermostat to work correctly in most  
installations. The sensors and modes may be selected from  
either the local settings menu or via Parameter 2;  
”Sensor mode (“OPER”)”.  
This icon will be displayed while the relay is on and the  
device is in Cooling mode.  
This icon shows the current signal strength.  
24.CHILD LOCK  
Available sensor modes:  
Child lock is a function for disabling the buttons from the  
display locally. It will show “LOCK” when attempting to  
operate it while the function is enabled. To enable or disable  
the function, hold the Left and Right buttons for 10 seconds.  
Enabling the function will show “LOCK” in the display, disabling  
the function will show “OPEN”.

External room sensor  
External room sensor + Floor sensor  
PWER Power regulator mode (no sensor used)  
NOTE: Some types of floors require a limit of 27°C for the floor  
temperature (check the manual from the floor manufacturer).  
An external floor sensor must be connected to monitor and  
control the floor temperature when A2F is selected. By default,  
the floor temperature maximum limit is set to 27°C. The  
minimum and maximum temperature limits are 2°C and 40°C  
respectively.  
25.OPEN WINDOW DETECTION OWD  
Open Window Detection (OWD) is a function which will  
reduce the thermostat setpoint on detection of an open  
window. This happens when the temperature sensor registers  
a rapid temperature drop.  
When OWD is active, the setpoint is reduced to 5°C in order  
not to waste energy. OWD will automatically be cancelled  
if OWD has been active for more than 1 hour, or if the  
temperature increases by 3°C. OWD can also be cancelled  
manually by increasing/decreasing the setpoint with the Left  
and Right buttons.  
19. SELECTING SENSOR VALUE  
The thermostat allows the selection of multiple different  
resistance values of a NTC sensor and can be selected using  
either the local settings menu or via Parameter 3: ”Sensor value  
“SEN”. The supported sensor values are as follows:  
6.8, 10, 12, 15, 22, 33, 47 or 100KΩ.  
By default, OWD is not enabled. The feature may be enabled  
by selecting “OWD” from the menu. Choose between options  
“OFF” and “ON”. It can also be enabled by setting parameter 25  
(open window detection) to 1.  
The factory default value is 10kΩ. When connecting both the  
floor sensor and the external sensor, make sure to use sensors  
with the same Ohm value.  
20.CALIBRATION  
26.MODBUS  
If the temperature sensor readout is not correct, you can make  
minor changes to the temperature readout. The temperature  
readings can be calibrated by 6°C using Parameter 8 and 9.  
The calibration can also be performed from the menu using  
CAE and CAF. The adjusted value will be displayed in the  
controller/gateway indicating what the thermostat uses for  
regulation.  
The Modbus protocol implemented is RS485. This uses  
Differential data communication through 3 wires: Ground, A  
and B. A and B are Data+ and Data- respectively.  
The default value for Device ID (Slave ID) is 1. This can be  
changed through the menu option SLAV. The value  
can be set from 1 to 250.
