Parts of supply air unit ECO4

1.

  Rear part, collar, heating element, electronic part and contacts for 

supply voltage (230V) and for the regulator 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 supply air unit ECO4 

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 10 

mm (see Figure 1.1).

3.

 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 regulator (KLMA) to the terminals of the electronic part 
of the supply air unit as shown on Figure 4.

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.

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 RCL ECO series to the regulator 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 regulator as shown on figure 5.  

5.

 When two or more supply air units are controlled with one regulating 

unit, the G pole of the power unit in only one supply air unit is con-
nected. The poles G0 and A2 are again connected from all controlled 
power units. The supply air devices must be connected in the same 
phase in the distribution box.

Note! Connection work may be performed only by a 
person with necessary professional skills.

WARNING! 230V voltage inside the unit.

Taking into use

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 regu-
lator 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 regulator 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 regulator and turn the 
temperature control knob (4) up (extreme position). Re-
move 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, remo-
ve jumper S2. Temperature drop from the setting value 
of 3ºC...10ºC is adjusted from the knob (8).

5. 

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 regulator:

1. 

Bring the cable intended for the regulator unit (KLMA) from the 
supply air unit either to the instrument box (60 mm spacing bet-
ween holes) or directly to a surface-mounted ECO regulator.

2. 

Remove the cover (2) of the regulator 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 regulator 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 regulator.
