1. GENERAL DESCRIPTION
• HMI controller is compatible with LEO FB V–type water heaters.
• Automatic or manual 3–step fan speed adjustment.
• Control room temperature (by opening/closing the valve, or by
adjusting air volume automatically).
• Antifreeze mode – protection against dropping room temperature
below critical level.
• HMI controls up to 6 LEO V–type units (it is required to use RX signal
distributor while connecting more than one unit).
• Possibility to connect external NTC temperature sensor.
Power supply 230VAC/50Hz
Regulation Panel buttons / LCD display
Setpoint range +5 ÷ +40°C
Speed of the fan control range 3 steps
Storage conditions temperature –10 ÷ +60°C
Ambient temperature range 0 ÷ +50°C
Temperature sensor Built–in internal/
external NTC (option)
IP 20
Montage surface
Casing ABS & Acrylic material
Weekly programmer ON: 5d+2d, OFF
Rated switching power 830 W (single–phase motor)

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.
• To change option use MODE button.
• To change value use +/– buttons.
