4. FUNCTIONS AND MODES
4.1 Function modes
MANUAL MODE – Fan is operating with chosen speed (LOW, MED or
HI). There are three additional modes: Heating, Cooling and Ventilation.
According to set temperature, valve is opened/closed.
AUTOMATIC MODE – air volume V is regulated automatically
depending on differential between pre–set Set Temperature (3) and
measured Room Temperature (2) (there is no possibility to change fan
speed manually). In this mode there is possibility to resign from the
valve, heating source will control ow and proper temperature of
water.
4.2 Fan function
To choose fan function see point 5.1.
Continuous – after reaching pre–set temperature (3) valve is closed,
fan operating with:
MANUAL MODE - pre set speed (1)
AUTO MODE - low speed
Thermostatic – after reaching pre–set temperature (3) valve is closed,
fan stops operating.
4.3 Working mode
Heating – valve is open and fan is on when Room Temp. < Set Temp.
Cooling – valve is open and fan is on when Room Temp. > Set Temp.
Ventilation – fan is turned ON and operate with pre–set V.

4.4 Temperature sensor
To choose sensor see point 5.1.
Internal – room temperature is measured by built–in sensor.
External – room temperature measured by external sensor NTC
(optional). It is possible to connect one external NTC sensor to one HMI.
NOTE!
Alarm will appear if there is error with internal or external
temperature sensor: E0.
4.5 Antifreeze
When external sensor or internal sensor detect temperature below 5°C
(default setting), valve and fan is about to open immediately even if the
thermostat is set on OFF status.
5. SETTINGS MENU
5.1 Parameters setting
• When HMI is switched off, press and hold MODE for 3 seconds.

• Remarks
• During setting, displays can be set while they are flickering.
• When the beginning time is flickering, it is able to be set
(10 mins each step) via scrolling + – buttons. The time setting
is the beginning of current time zone, also the end time of last
time zone.
• When ON/OFF is flickering, it is able to be set via scrolling + –
buttons. When status is ON, thermostat will run according to
setpoint; when status is OFF, thermostat will be switch off
• When the setpoint is flickering, it is able to be set via
scrolling + – buttons. Even choosing OFF status, setpoint is able
to set. And this setpoint will be the working if someone switch
thermostat ON manually this time; however in next time zone,
it will run according to automatic programmable setting.

• Example
• As ex–factory setting, press FAN button for 3 sec and enter into
programmable setting; from Mon to Fri display on the left top
of LCD; the time is flickering, and the beginning time of 1st
time zone we should enter 06:00( also it is ending time of 6th
time zone); then press FAN again, to choose ON by scrolling
+ – ; Continually press FAN again, to set 26°C by scrolling + –
buttons.
• Press FAN again, to set the beginning time of 2nd time zone
at 08:00 (also it is the ending time of 1st time zone); then press
FAN again, to choose ON by scrolling + – ; continually press
again, to set 24°C by scrolling + – buttons
• Press FAN again and follow the same steps to set time zones
from 3rd to 6th time, 22:00 is the beginning time of 6th time
zone, also the ending time of 5th time zone.
• After 6 time zones for Mon to Fri are done, keep pressing FAN
again and move to Sat. to set data by same steps; press FAN
again and move to Sun. to set data by same steps.
• After all settings are done, please press FAN or wait for
5 seconds to confirm settings.
7. INSTALLATION
NOTE!
Mind to disconnect HMI panel before starting work. Control panel

• Umożliwia 3–stopniowa nastawa prędkości obrotowej wentylatora.
• Kontrola temperatury w pomieszczeniu (poprzez otwieranie/za-
mykanie zaworu, albo automatyczną nastawę prędkości obrotowej
wentylatora V).
• Antifreeze – zapobiega nadmiernemu spadkowi temperatury
w pomieszczeniu.
• HMI może może obsłużyć do 6 urządzeń LEO FB V (wymagane jest
użycie rozdzielacza sygnału RX w przypadku podłączenia więcej niż
jednego urządzenia).
• Możliwość podłączenia zewnętrznego czujnika temperatury NTC.
