DIP SWITCHES SETTING
Modify the Dip Switches inside the DRA‐L NET control as per:
•
Installed unit;
•
Water unit installation position;
•
Operation logic.
Dip Switches functions:
Dip Switch no.
Dip Switch no.
NOTES:
(1) on demand in heating, continuous in cooling.
(2) no Hot Start and Too Cool.
To enter the DIP Switches, follow this procedure:
•
First, separate the connectors' base plate from the main interface by means of a small screwdriver – insert the screwdriver
into the special holes (onto the container's side) and slightly twist until the two parts are divided;
•
By turning the back of the main interface, it is possible to see the Dip Switches fitted onto the printed circuit board.
8.5 WATER PROBE
• Install the probe downstream the valve and insulate it by means of aluminium tape;
•
As for the 4‐pipe systems, it has always to be fitted onto the hot water circuit, and never onto the cold water one;
•
Use only the probe supplied as accessory – NTC temperature probe, reinforced insulation, PVC cable, cable length = 1,5 m.
Note: Set the no.3 Dip Switch on the ON position –valve thermal regulation.
