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.
