2. STRUCTURE, INTENDED USE, PRINCIPLE OF OPERATION
2.1 INTENDED USE
Powrmatic WX has been designed to ensure ease of use and optimum performance.
The device is available in FOUR versions:
Powrmatic WX combines state-of-the-art technology, innovative design and high effectiveness. Unique technical solutions such as the design of the heat exchanger, improved fan and
increased range of air stream, allow the WX heater to achieve optimal heating power, perfect for the size and type of room. APPLICATION: production halls, warehouses, wholesale outlets,
sports facilities, greenhouses, supermarkets, church buildings, farm buildings, workshops, health care facilities, pharmacies, hospitals. It is allowed to use Powrmatic WX air heaters in rooms
with high humidity (without condensation) i.e. car washes, provided that the unit is not exposed to direct impact of the water strIt is allowed to use Powrmatic WX air heaters in rooms with high
humidity (without condensation) i.e. car washes, provided that the unit is not exposed to direct impact of the water stream. Prohibition of using Powrmatic WX air heaters in rooms with
aggressive environment (i.e. high concentration of ammonia) that can cause corrosion of aluminium or copper.
MAIN ADVANTAGES: high effectiveness, low maintenance costs, full parameter control, easy and quick assembly.
2.2 PRINCIPLE OF OPERATION
The heating medium (hot water) gives up heat to the heat exchanger using a highly developed heat exchanger, ensuring great heating power (Powrmatic WX-1-EC – 10.4-15.3 kW, Powrmatic
WX-2-EC – 15.6-22.0 kW, Powrmatic WX-3-EC – 24.2-36.7 kW, Powrmatic WX-4-EC – 36.7-55.0 kW). A highly effective axial fan (1100-5700 m3/h) draws air in from the room, pumps it
through the heat exchanger and then sends it back into the room. Powrmatic WX heater de-stratifies the heated air from the sub-ceiling zone to the above-ground zone. Hot air exhaust results
in a leveling of the temperature gradient in particular air layers and contributes to reducing the costs of heating by lowering the temperature in the ceiling zone, thus limiting heat loss through
the roof. Cooperation of these device types will allow for achieving optimal temperature comfort fast due to the support of the heating system through more efficient distribution of hot air.
Powrmatic WX-1-EC (10.4 - 15.3kW @ 80/60°C, 1100 - 2100m³/h)
Powrmatic WX-2-EC (15.6 - 22.0kW @ 80/60°C, 2800 - 5300m³/h)
Powrmatic WX-3-EC (24.2 - 36.7kW @ 80/60°C, 2400 - 4850m³/h)
Powrmatic WX-4-EC (36.7 - 55.0kW @ 80/60°C, 3000 - 5700m³/h)

5. SAMPLE CONSOLE
1. EN: HEAT EXCHANGER: maximum parameters of a heating medium for a heat exchanger are: 130°C, 1,6MPa. Aluminium and copper construction using copper tubes, coil pipe and
aluminium lamellas. Connecting ferrules (male thread ¾”) are on the back panel of the unit. Our series of types includes a single-row heat exchanger in the Powrmatic WX-2-EC – 15.6-22.0
kW and two-row heat exchanger in the Powrmatic WX-1-EC – 10.4-15.3 kW and Powrmatic WX-3-EC – 24.2-36.7 kW, Powrmatic WX-4-EC – 36.7-55.0 kW - three-row heat exchanger. The
glycol concentration in the heating medium can be up to 50%.
2. AXIAL FLOW FAN: maximum working temperature is 60°C, nominal power supply voltage is 230V/50Hz. AC Engine protection is IP54, insulation class F for EC motors IP is 54. Air feed is
performed by the axial flow fan, which i s secured with a protective grate. Adequate blade profile a nd proper bearings guarantee silent and unfailing operation o f the device. High engine
power allows for achieving high efficiency at low power consumption rates, maintaining full air feed regulation. Properly profiled housing lowers the noise emission levels, which makes the
device particularly user-friendly, suitable for buildings with higher acoustic requirements.
3. HOUSING: consists of the body and the front panel, made of high quality plastic guaranteeing compatibility with devices powered by heating medium with temperature parameter up to 130°C.
4. AIR GUIDES: allow the hot air stream to be directed in 4 directions. Optimum air stream range and direction are achieved through the special fan blade profile.
5. ASSEMBLY CONSOLE: an element of additional equipment - its ergonomic, light structure allows for rotating the device on the horizontal plane for -60°÷0÷60°, to direct the stream of hot air
wherever it is necessary.

6. START-UP, OPERATION, MAINTENANCE
6.1 START-UP/PUTTING INTO OPERATION
● Prior to any installation or maintenance works, disconnect the device from the power supply and secure it against accidental power-up.
● Use filters in the hydraulic system. Before you connect the hydraulic lines (especially supply lines) to the device, you should clean/rinse the installation by draining a few litres out of it.
● Install vent valves at the highest point of the installation.
● Install cut-off valves directly behind the device, so it can be easily disassembled.
● Secure the device against pressure increase according to the permitted maximum pressure value of 1.6 MPa.
● Hydraulic pipes need to be free from any stresses and loads.
● Prior to the first start-up of the heater, check the hydraulic connections (vent and collector air-tightness, installed fittings).
● Prior to the first start-up of the heater, check the electric connections (connection of automatic devices, power supply, fan).
● It is suggested to use additional external current differential protection.
NOTE All connections should be made according to this technical documentation and the documentation enclosed with the automatic devices.
6.2 OPERATION AND MAINTENANCE
● Device casing does not require any maintenance.
● Heat exchanger needs to be regularly cleaned of dirt and grease. Especially before the heating season, the heat exchanger needs to be cleaned with the use of compressed air on the
side of the air guides (but the device does not need to be disassembled). Pay attention to the exchanger’s lamellas, as these are delicate.
● If lamellas bend, straighten them with a special tool.
● The fan motor does not require any maintenance. It may only require cleaning of the protective mesh, fan blades and dust and grease deposits.
● If the device is not used for a long time, disconnect the voltage supply.
● Heat exchanger does not have fire protection.
● It is recommended to periodically blow through the heat exchanger, preferably with compressed air.
● The heat exchanger can freeze (fracture) when the room temperature falls below 0°C and the heating agent temperature decreases at the same time.

10.1 PROCEDURES IN CASE OF DEFECTS
WX-1-EC/WX-2-EC/WX3-EC/WX4-EC
Problem Check points Description
Heat exchanger leaking
● assembly of the exchanger connections with two wrenches (adjustment), which
safeguards against internal twisting of the collectors,
● Check if the leakage may be associated with mechanical damage to the
exchanger,
● Vent valve or drain plug leaking,
● Heating agent parameters (pressure and temperature) – should not exceed
permitted values,
● type of heating agent (it cannot be aggressive to Al and Cu),
● Circumstances when the leakage appears (e.g. during the first, tentative
installation start-up, when the installation is filled up after the heating agent
has been drained) and outside temperature at the time of failure (risk that the
exchanger may freeze),
● Possibility of operating in aggressive conditions (e.g. high concentration of
ammonia in the air in a sewage-treatment plant),
Pay special attention that the exchanger may freeze during winter
time. 99% of registered leakages appear during installation start-up/
pressure tests. The defect can be removed by pulling back vent or
drain valve.
Fan works too loud
● check the device assembly for conformity with the instructions in operation and
maintenance manual (e.g. distance from wall/ceiling), min. 40 cm
● Device appropriately level led,
● Correctness of electric connections and qualifications of the wireman,
● Inlet current parameters (e.g. voltage, frequency),
● use of rotation controller different from ARW,
● noise at lower gears (possible controller failure?),
● Noise only at higher gears (regular situation explained by aerodynamic
characteristics of the device, if there outlet air chokes),
● type of other devices operating in the building (e.g. induced draught fans) –
intensified noise caused by simultaneous operation of many machines,
● Does the fan rub against the casing?
● Is the fan evenly screwed to the casing?
Level of operating noise of the devices is perceived subjectively. If
the device is made of plastic, it should operate quietly.It is
recommended to unscrew the clamping screws and tightening them
up again. If the fault does not disappear, you should make a
complaint.
Fan does not work
● Correctness and quality of electric connections and qualifications of the wireman,
● Is there an additional bridge between required engine terminals (diagram in the
manual) – U1 – TK (TB),
● Inlet current parameters (e.g. voltage, frequency) on the clamp block of fan
engine,
● Correctness of operation of other devices installed in the building,
● Correctness of wire connections on the engine side acc. to the manual, in
comparison to wires clamped in the engine terminal strip,
● PE conductor voltage (if present, may mean there is a break-down),
● Is N conductor correctly connected to the fan or ARW or is the connection of U2
clamps on the motor and ARW made correctly?
Electrical connection need to be done strictly according to the
drawings in the manual. If there is no bridge between U1 and
TK(TB) clamps, the motor lacks thermal protection and may break
– burn.
● damage or installation of controller different from ARW, It is recommended to check the device/ speed controller by
connecting the heater directly to power supply.
Damaged casing ● Circumstances when it was damaged – notes on the bill of ladings, stock issue
confirmation, condition of the box,
If the casing is damaged, make photos of the box and device, and
photos confirming that the device serial number on the device
and on the box are the same. If the device was damaged during
transport, it is necessary to write down an appropriate statement by
the driver, who delivered the damaged device.
ARW – rotation controller
does not work/ it is burned
● Correctness – quality of electric connections (wires accurately positioned
in electric clamps, cross-section and the material wires are made of) and
qualifications of the wireman,
● Only 1 controller connected to 1 device,
● Inlet current parameters (e.g. voltage, frequency),
● Correctness of operation after connecting “in short” (skipping ARW, i.e.
connections L and TB, N and U2, PE and PE) to the power network,
● Check if the user did not damage the knob, e.g. rotating it around
For the TRANSRATE controller, the following must also be
checked:
● circuit breaker,
● correctness of connection to the SCR10 controller,
● use of shielded conductors,
● control conductors, which should be located away from the
working conductors
Actuator does not open
the valve
● Correctness of electric connections and qualifications of the wireman,
● Correctness of the thermostat operation (characteristic tick sound during change-
over),
● Inlet current parameters (e.g. voltage),
The most important is to check whether the actuator responded
to the electric impulse within 11s. If the motor is damaged, you
need to make a complain and switch actuator operation to manual
(MAN), which mechanically opens the valve.
Programmable thermostat
does not send any signals
to the actuator/ controls
the operation of the
heating system wrongly
● Correctness of electric connections and qualifications of the wireman,
● Correctness of the thermostat operation (characteristic tick sound during switch-
over),
● Connecting a few motor of the devices directly to the thermostat
(permitted only if contactor is used!),
● Inlet current parameters (e.g. voltage),
● Programming method exactly the same as in the manual
● When was the last time the sensor was calibrated?
RDE thermostat is powered by batteries, that need to be replaced
(every 2 years). Also, the sensor needs to be periodically calibrated
– detailed information can be found on: www.vtsgroup.com
Complaint is unjustified, if the RDE thermostat was directly
connected to the motor, without a contactor. If the sensor incorrectly
measures the temperature, it should be calibrated (instructions in
the catalogue).
