7. Automatic control - installation
A set of automatic control may be used (powered 230V) that consists of the following:
• COMFORT panel - including room thermostat and switch for regulation of 3 speeds of fan. One COMFORT panel may regulate up to
3 pcs of Solano Eco 1, 2 and 3 units or 2 pcs of Solano Eco MAX
• 2-way water valve with actuator; valve should be installed on a return stub of the heater
• INTELLIGENT electronic control panel with an automatic speed controller, weekly program and BMS communication.
One INTELLIGENT panel may regulate up to 2 pcs of Solano Eco units or for single Solano Eco MAX
• Splitter MULTI 6 - control up to 6 pcs of Solano Eco, Solano Eco MAX units from one COMFORT or INTELLIGENT Panel
The system is ready to start once the connections between the thermostat and the valve actuator are done, 230V power is supplied to
the thermostat and the fan's motor is powered by the revs controller.
8. First start
Do all the connections (electrical, water and automatic control), check for tightness of all connections done by an installer and
air-release/vent the device then start the device in the following sequence:
1. Switch on the mains,
2. Set requested speed of fan on revs controller,
3. Set requested temperature on thermostat,
The fan operates continuously irrespective of whether the heater's valve is opened or not.
9. Turning off
To switch the device off do the following:
1. Set minimum temperature on thermostat - after 7 seconds valve will be closed and heating switched off.
2. Set main switch to the "0" position (off); fan will be switched off and the thermostat will be off the power.
10. Operation
The engine and fan used in Solano Eco and Eco MAX units are maintenance-free devices but regular check-ups are advised, especially
motor and bearing (fan's rotor should rotate freely, free from any axial and radial throws and undesired knocks/rattles).
NOTICE!
• In case of any metallic knocks, vibration or increase in sound level check if the fan mounting/fixing does not work loose contact

11. Maintenance
The heat exchanger requires systematical cleaning all with all dirt/impurities cleaned off. Before the start of the heating period the heat
ex-changer is advised to be cleaned with compressed air directed to the air outlets; there is no need for dismantling of the device. Pay
special attention when cleaning the exchanger's fin due to high possibility of damaging them. If fins are bent use a tool specifically
designated to carry out such repairs. If the device has not been used for a longer period of time, unplug it before the next use.
The heat exchanger is not equipped with any frost protection device. The heat exchanger may be damaged if the room temperature
goes below 0°C.
Anti-freeze liquid must be added to the water circulation/system. Anti-freeze liquid must be appropriate for the material the exchanger
is made of (copper) as well as other elements of the hydraulic system. The liquid must be diluted with water according to the solution
recommended by the anti-freeze manufacturer.
COMFORT panel description
ON/OFF - turning ON/OFF a unit
I-II-III - switch for fan speed regulation
HEAT - thermostat sends signal for valve and actuator and fan, fan turns off when temperature in
room is achieved, valve/actuator closes water supply.
FAN - function not active, unit will not operate when FAN switch is selected
COOL - thermostat sends signal only to fan and to the servo of the valve, fan begins operation
starting from temperature which is set on thermostat (function used to air mixer Solano MIX or for
room ventilation in summer season)
