Parts of the air-forced heater ECO2
1. Rear part, collar, heating element, electronic part and contacts for
supply voltage (230V) and for the thermostat cabling
2. Perforated cover
3. Fixing screw for the perforated cover (2 pcs)
4. Fixing screw for the rear part (to a wall, 4 pcs)
Installation of the air-forced heater ECO2
1. Drill holes into the wall for wires and fixing screws (4), using the
cutout template supplied with the delivery (for the cutout template
see Appendix 1).
2. The minimum distance of the supply air unit from the ceiling is
70 mm (see Figure 1.1). The minimum installation height from the
floor is 1,8 m. The diuser must be installed in a place where children
can’t touch it without supervision.
3. Remove the two fixing screws (3) of the perforated cover (2) and pull
the cover away from the rear part (1).
4. Push the collar of the rear part inside the supply air duct and fix the
rear part to the wall, using four screws (4), Ø max 5 mm.
5. Connect the supply cable of the supply air unit (MMJ) and the control
cable of the thermostat (KLMA) to the terminals of the electronic
part of the supply air unit as shown on Figure 2.
6. Check that all the connections are correct. Push the perforated cover
back onto the rear part and fix it properly using the fixing screws of
the cover.
7. Mark the power switch and temperature drop function switch clearly.
Connection
1. Connect supply voltage (230V) to terminals N and L of the electronic
part of the supply air unit as shown on Figure 2.
2. Connect the grounding to the separate ground terminal in the supply
air unit as shown on Figure 2.
3. Connect the supply air unit of the ECO series to the thermostat by
means of the KLMA cable as shown on Figure 2.
4. You can activate temperature drop function by connecting terminals
Z1 and G0 in the thermostat as shown on figure 5.
5. When two or more forced-air heaters are controlled with one ther-
mostat, the G pole of the power unit in only one supply air unit is
connected. The poles G0 and A2 are again connected from all con-
trolled power units. The supply air devices must be connected in the
same phase in the distribution box.
Note! Connection may be performed only by
a person with necessary professional skills.
WARNING! 230V voltage inside the unit.

Commissioning
1. Make sure that the connections are made correctly.
Turn on the 230V supply voltage coming to the supply air
unit. The display (7) will show the room temperature and
the LED (6) will light up. The factory setting of the ther-
mostat is 21ºC (central point of the setting area) and if
the room temperature is lower, the led will turn red and
the heating will be switched on, otherwise a green led
will be illuminated.
2. When the value of the thermostat is changed (± 3ºC from
the value of the central point) with the control knob (4),
you can see the new setting value on the display (7).
3. Changing the central point of the setting area to e.g. 24ºC.
Open the cover (2) of the thermostat and turn the tem-
perature control knob (4) up (extreme position). Remove
jumper S3 and install it back to its position. The new
central point of the setting area will now be 24ºC.
4. The factory set accuracy of temperature adjustment is
± 0.5ºC. If you need to change the accuracy to ± 1ºC,
remove jumper S2.
5. Temperature drop from the setting value of 3ºC...10ºC
is adjusted from the knob (8). The value of temperature
drop is visible on the display (7).
6. After you have made all the necessary changes, reinstall
the cover (2) and the system is ready for use.
Installation of the thermostat:
1. Bring the cable intended for the thermostat unit (KLMA)
from the supply air unit either to the instrument box
(60 mm spacing between holes) or directly to a surface-
mounted ECO thermostat.
2. Remove the cover (2) of the thermostat from the rear part
(1), using e.g. a small screwdriver (clips at the upper and lower
edge of the thermostat).
3. Fix the rear part of the thermostat either to the instrument
box or directly on the wall, using screws (3).
4. Connect the cables to the terminal block (5) as shown on
Figure 2.
5. If the temperature drop function is taken into use, connect
it as shown on Figure 5.
6. After all the connection work, check the connections and
reinstall the cover of the thermostat.
