Installing / dismantling the controller  

a. 

TFT panel 

 

Ensure that the power is turned off ! 

 

Cable for connecting the controller should be derived from the wall – preferably, it is mounted in a typical box as 
electrical equipment (power sockets, switches .... etc.) 

 

Next, drill two holes in the wall for wall plugs, symmetrically to the can. These holes should be done horizontally with 
ce of 89mm.

control panel case consists of two halves, connected to the latch. You must gently divide them. You can help yourself 
with a flat screwdriver, undermining the special holes in the cover (bottom left or top right corner of the housing). 

 

Mount to the wall with screws. 

 

The cable should be connected to the upper half of the housing containing the electronics controller. Excess cable 
should be put in a box in the wall. 

 

The cable mustn't be shortened or extended!

 

 

 

Connect gently upper and lower half. 

 
 

b. 

The relay module 

 

Installation and wiring must be carried out with power off! 

 

Diagrams are supplied separately. 

 

The module should be mounted in a recuperator or as close as possible so that the fan power cables are as short as 
possible. 

 

To connect wires use screwdriver type philips PH0 

 

The recuperator power supply must be protected with appropriate fuse. 

 

The electrical connection should be made by person with the appropriate permissions. 

 
 
To dismantling controller to pieces use screwdriver PH0 and to separate TFT from pcb use hot air desolder. 
 
NOTE !!!

 – Connecting should be done carefully and accurately according to the scheme. Connect the adequate colors in the 

appropriate connector line in the module relays. Different connection from the schema can cause damage to the driver!
