1. OVERALL INFORMATION
HEATER CONDENS heating and ventilation devices are designed to be applied in the buildings of small and medium capacity,
especially such as: production and warehouse halls, car showrooms and service stations, sports halls and stadiums, sacral build-
ings and churches, retail stores and wholesales outlets, agricultural facilities, exhibition surfaces. HEATER CONDENS is a special,
dedicated solution to be connected to low water temperature sources (for ex. condensing boilers, industrial heat pumps). Main
advantages of HEATER CONDENS are: high temperature of exhaust air generated by low temperature of water supplied
to a unit, maximum use of water coil surface –new geometry of coil construction (enhanced fins size, lower space be-
tween fins), optimized air flow exhaust –in effect high air exhaust temperature generated on each speed of fan.

3. GENERAL INFORMATION
HEATER CONDENS heating and ventilation devices are manufactured in compliance with standards concerning quality, ecology,
utility and work comfort. HEATER CONDENS devices are delivered ready-to-use in a cardboard package that is to protect from
mechanical damages. The package consists of: the device, the Manual (Operation and Maintenance Documentation) and Guar-
antee. If the optional automatic control ordered, it shall be delivered in a separate package. Make sure all the aforementioned
elements are in the package immediately after the delivery. In the absence of any element, please fill in the suitable carrier
document.
4. ASSEMBLY
Prior to any installation procedures, take the following aspects into consideration: easy access for maintenance works, access to
water and electrical installation, appropriate air distribution in a room.
Each HEATER unit is equipped with a set of 2 interchangeable colour inserts; in order to change the color, remove the insert
from the front panel and place the desired one back in place.
It is advisable to mount the device to the wall or the ceiling on original mounting brackets, supporting mount pins (not delivered
with the device) or supporting constructions (shapes and dimensions of the supporting construction may be individually de-
signed in compliance with durability and strength requirements).
In case of mounting to the ceiling, pay attention to the fact that air-release/venting of the device may be difficult so it is advis-
able to place vent at the highest point of the pipework.
The device may be mounted to the wall with the use of a mounting bracket at the angle of 0°, 30° or 60 °. A mounting bracket
holder is made of curved profile. It has two holes for vertical assembly. Assembly to the wall and/or to the ceiling is possible at
different angles but it requires making necessary holes in the holder.

Operation and maintenance documentation HEATER CONDENS v202103
NOTICE !
To sustain proper functioning of the device keep a safe distance–200 mm from its sides and 300 mm from its backside
(from the fan)
ATTENTION !
While drilling the holes in marked places be careful not to damage the coil by going deeper than 20mm!
Mounting bracket to the heater
The bracket set consist of: a holder, two sleeves, two
M8 screws and washers. In order to mount the brack-
et, drill two Ø12-13mm holes in places visibly marked
on the casing. Insert sleeves into drilled holes and
place the bracket in. The included holder must be
screwed with M8 screws with washers.

mounting pins. Drill two Ø8-9mm holes in places visi-
bly marked on the casing. Mounting pins may be
screwed into the frame of a heat exchanger to the
maximum depth of 20 mm. Mounting pins and con-
necting elements are not included with the unit

Operation and maintenance documentation HEATER CONDENS v202103
5. ELECTRICAL INSTALLATION
The electrical installation and connection to power supply must be done in compliance with the existing regulations and stand-
ards for building industry.
The fan’s engine is equipped with the internal temperature limit fuse protecting the engine from its overheating.
The unit set does not consist of: a feeding cable, a master switch (see diagram)
The electrical installation must be done by an authorized person, acquainted with the Manual. The connection of the feeding
cable and master switch must be done in compliance with electrical diagram (with or without the automatic control, depending
on the option chosen). Any and all damages incurred as a result of the aforementioned causes are not provided with the Guar-
antee and the user will be charged with any costs of the device exchange. The connection of the automatic control should be
carried out in accordance with the electrical diagram.
In case of any doubts or problems, unplug the device and contact the device’s installer or SONNIGER Authorized Service.
6. WATER INSTALLATION
The installation of the unit should be done in a way enabling maintenance service; on both stub pipes manual closing valves
should be installed in order to cut off the device. Feeding cables of the heater shall be connected in accordance with the sym-
bols/marking on the casing (inlet/outlet). In case of electromagnetic valve (with the option of the automatic control) it should
be installed on the outlet as it may be damaged otherwise. When the pipework is being connected to the exchanger, secure the
connections of the heater from oscillating torque (see figure) that may cause leakage in the exchanger.
Heating medium
The connector pipes are at the back of the
device. When connecting the hydraulic
pipes/connections, make sure you secure the
connector pipes against rotational torque.
Notice that the connector pipes are not
strained by the pipes. The valve of heating
medium is on the supply pipe and the vent is
on the return pipe.
Use flexible connections to allow the heater to
be turned to the sides. Depending on the
flexible connections, the maximum turn
is 70° - for HEATER CONDENS MAX,
78° - for HEATER CONDENS CR1, CR2, CR3,
68° - for HEATER CONDENS ONE , to both
sides. Figure shows maximum angle to one
side and 50° to the other with minimal dis-
tance left for connections.

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
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 regu-
late up to 6 pcs of HEATER CONDENS CR ONE, 3 pcs of HEATER CONDENS CR1,2,3 units or 2 pcs of HEATER CONDENS
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 HEATER CONDENS units or for single HEATER CONDENS MAX
Splitter MULTI 6 - control up to 6 pcs of HEATER CONDENS, HEATER CONDENS MAX or 12 pcs of HEATER CONDENS ONE
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 sup-
plied to the thermostat and the fan’s motor is powered by the revs controller.
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 HEATER MIX or for room ventilation in sum-
mer season)
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 CONDENS 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 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 fire protection device. The heat exchanger may be damaged if the room tempera-
ture 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 ex-
changer 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.

closes water supply.
FAN –function not active, unit will not operate when FAN switch is selected
COOL –thermostat sends signal only to fan and the servo of the valve, 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)
Attention! You can use additional jumper on the contacts 4-5 of COMFORT Panel, in this case you may only use function of
changing speed of fan I-II-III and ON / OFF. The thermostat and switches HEAT / FAN / COOL remain not active.
Additional jumper on terminals 4-5 might be applied when for ex different (supplied by user) thermostat is used to control the
system.
