Technical Documentation waterfan HEATER v201905
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 HEATER units
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 HEATER units
Splitter MULTI 6 - control up to 6 pcs of HEATER 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 HEATER 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).
11. MAINTENANCE
The heat exchanger requires systematical cleaning all dirts /impurities off. Before the start of the heating period the heat exchanger 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 fire 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/circulation. The liquid must be diluted with water according to the solution
recommended by the anti-freeze manufacturer.
NOTICE !
In case of any metallic knocks, vibration or increase in sound level check if the fan mounting/fixing does not work loose
contact the installer or SONNIGER Authorized Service
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 – termostat sends signal only to fan, fan begins operation starting from temperature which is set on
thermostat (function used to air mixer HEATER MIX or for room ventilation in summer season)
