mode min and max values specify active dial
range. In all other modes it guarantees maximum
pulse ratio. Note: Setting can be used, e.g., to
limit maximum heating power to comply with
installation standard EN50599. Cycle time of
PWM is 10 minutes.
Snow melting ON temperature min and max
Min and max setting specify the active knob
range. When outdoor temperature is below this
setting point the snow melting operation is ac-
tive.
Snow melting OFF temperature
When it is colder than this temperature the
snow melting is switched OFF.
Snow melting air humidity min
When wireless outdoor temperature sensor is
used the thermostat also receives air humidity
level. Snow melting function will not be activat-
ed if the air humidity is below this limit.
User program activated eco temp
During all green hours in user program the tem-
perature is adjusted to this value. This set value
is also used when eco state is seleced from the
menu.
Externally activated eco temp
When 230VAC (pilot signal) is connected to
the setback input terminal the temperature set
value is defined by this parameter.
Valve protection
Valve protection turns heating ON once per
week for 5 minutes even at summer time. This
setting is typically used with water carrier floor
heating valves. Feature prevents the valve from
getting stuck during summer.
Sensor type
Floor sensors from different manufacturers can
be used. Supported types are 2k, 10k, 12.5k, 15k,
33k NTCs.
Display brightness in standby
Brightness of the OLED display when it is
dimmed in standby mode. Notice that standby
brightness affects the lifetime of OLED display.
User program mode
AUTO enables the user program, OFF disables
it.
Wireless temperature sensor
Adding a wireless BLE temperature sensor al-
lows the best location for temperature measure-
ment. It is very accurate and also measures the
air humidity. To add a wireless sensor you have
to select it in the ecoControl App and write the
sensor address in Network key fields.
Receive wireless eco controls
A thermostat with an external setback switch
can control several other thermostats to go in
setback mode. This feature will save the user
from hard wiring the Home/Away switch to
many thermostats. To form a group of thermo-
stats you need to enable the Receive wireless
eco controls and write a freely selectable group
name in Network key fields.
Network key and Confirm Network key
Network key is used to identify the wireless
temperature sensor or the group of thermostats
to receive the wireless eco controls. Both fields
need to have exactly the same text string and
you have to save the settings. For the wireless
sensor you can use the QR code printed on the
back side of the device. Just use the App cam-
era function (bottom of the screen) to read the
code, then accept and save it.

Week schedule
User can create 7d/24h week schedule in
ecoControl App. With week schedule the user
programs thermostat to decrease temperature
during time slots when room is not used.
Comfort/eco state is indicated on the set value
page.
6
Week schedule execution needs correct real
time in thermostat. In case of invalid real time
the week program is deactivated and user is
warned by the error message on screen. Real
time is updated from ecoControl App every time
the thermostat is connected to a mobile phone.
Real time has backup to power shortages of up
to 2 hours.

Error modes
Thermostat indicates an erratic state by display-
ing the text ERROR and the error code. The
most typical case is that real time is corrupted
during too long power break. This is automati-
cally solved by taking connection with ecoCon-
trol app. Possible error codes are
1 Floor sensor fault
2 Over heat
3 Internal fault
10 Calendar time is not valid
You may try to reset the fault by switching off
the power, to soft reset or by using ecoControl
App to generate a hard reset.
In errors 1, 2, 3 heating is permanently off. In er-
ror 10 user program is deactivated.
