By pressing any button once, you will see the measured
temperature. By pressing the Left or Right button multiple
times, you will change the setpoint.
15. 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.
16. SIZE OF LOAD
In the “load” menu or from Parameter 29 (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.
17. 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”)”.
Available sensor modes:
FFloor sensor
AInternal room sensor
AF Internal room sensor + Floor sensor
A2 External room sensor
A2F External room sensor + Floor sensor
PWER Power regulator mode (no sensor used)
NOTE: Some types of floor require that a floor sensor
is connected in order to limit the floor temperature to
a maximum of 27°C (check the manual from the floor
manufacturer). When the thermostat is used in (AF or A2F) the
floor limiter FHI is automatically set to 27°C. When using any
other sensor type (A, F or A2) the minimum and maximum
limits are 5°C and 40°C respectively.
18. SELECTING SENSOR VALUE
The thermostat allows the selection of multiple dierent
resistance values of an 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.
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.
19. CALIBRATION
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 10, 11
and 12. The calibration can also be performed from the menu
using CAR, CAE and CAF. The adjusted value will be displayed
in the controller/gateway indicating what the thermostat uses
for regulation.
9. STARTUP
After powering up the device for the first time, all parameters
will have default settings and the thermostat will start by asking
which sensor mode should be used.
10.PRINCIPLES OF REGULATION
The thermostat uses temperature readings retrieved from the
internal sensor and/or from external wired sensors to regulate
the temperature. The thermostat will regulate the temperature
using hysteresis or PWM, based on the setpoint temperature.
To select either “HYST” or “PWM” you can find the “REG” menu
option or use Parameter 13 “Regulation mode (“OPER”)”.
10.1 Hysteresis
Hysteresis will turn on and o the load based on the hysteresis
value in comparison to the setpoint. You can make changes
to the thermostat hysteresis. You may choose hysteresis
values between 0.3°C and 3.0°C using Parameter 14. The
default setting is 0.5°C. When using waterbased heating we
recommend a hysteresis of 1.0°C.
You may also change the hysteresis by entering the local
settings menu and holding the Center button for 2 seconds
when “REG” is displayed. Here you can choose values
between 0.3 and 3.0.
10.2 Pulse-width modulation PWM
With PWM regulation enabled, the thermostat will regulate
based on duty cycles. The thermostat is turned on and o in
percentage intervals of the cycle. The amount of time the relay
will be on is based on how far the measured temperature is
from the setpoint.
11. LOCAL SETTINGS MENU
To enter the settings menu, hold the Center button for 5
seconds. The display will display “OFF”. You are now in the
settings menu. While in the settings menu, “SET” will be
displayed in the bottom right of the display. You can now scroll
up and down using the Left and Right buttons. Some options
have submenus. To navigate the submenus, press the Center
button once to enter or exit the submenu. Press the Left and
Right buttons to find your desired value and hold the Center
button for 2 seconds to confirm your selection. “STOR” will
appear to indicate settings are stored.
12. DISPLAY MENU STRUCTURE
See flowchart at the end of this manual.
13. TEMPERATURE SHOWN IN DISPLAY
By default, the temperature shown on the display while
in standby state is the setpoint. This may be altered with
Parameter 15:”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.
14.STANDBY AND MAIN SCREEN
When the thermostat remains untouched for a while, it will
automatically go to the standby screen. The standby will by
default show the setpoint temperature.
