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 + 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.
