FWECSA

Controller for units

entrance of the exchanger in the heating circuit.

FWB-FWP

Example, valves installed on the left side:

System pipe
supplied by the customer

• 

For FWB-FWP units without valves, for 2-pipe systems, 
the water probe must be positioned on the pipe at the 
entrance of the exchanger.

• 

For FWB-FWP units without valves, for 4-pipe systems, 
the water probe must be positioned on the pipe at the 
entrance of the exchanger in the heating circuit.

USER UNIT INSTALLATION

Choose an area to install the controller panel which is easily 
accessible to set functions and efficient for room temperature 
detection (at least 1.5 m from the floor). Therefore, avoid:

• 

direct sunlight exposure;

• 

direct exposure to hot or cold air currents;

• 

placing obstacles which impair correct temperature 
detection (cur tains or furniture);

• 

the constant presence of water vapour (kitchens, etc.):

• 

covering or recessing the panel into the wall.

For wall installation of the controller, it is advisable to use 
a recessed 503 electrical contact box behind the controller 
to house the wires. For installation, follow the instructions 
below:

• 

Remove the controller's closing screw 

(figure 13)

.

• 

If a 503 enclosed gang box is used, pass the cables 
through the slot at the bottom of the controller and use 
the relative holes for fastening 

(figure 13)

.

• 

Otherwise drill a hole in the wall, for the fastening 
holes on the base of the controller, where you wish to 
install the controller. Use the base of the controller as 
a template to mark the position of the holes. Pass the 
cables through the slots on the base and fasten it with 
plugs onto the previously drilled wall 

(figure 14)

.

• 

Connect the clamp to the display board.

• 

Close the controller back up using the closing screw.

The connection between the panel and the controller and 
the I/O board must be set up using the 2-clamp connectors 
for conveyed waves installed on both devices (see electrical 
diagram). With the I/O board, there are 2 connectors to set 
up the connection: it makes no difference which connector is 
used. It is necessary to use a data cable for networks with a 
pair of twisted conductors and shielding. It is also necessary 
to connect the shielding conductor to the clamp (-) on the 
user side and on the I/O board
