Ptouchremotecontrolpanelisdesignedfor:
• SALDA ventilation units and other devices based on PRV, MCB or ECO controllers;
• Modbus-controlled devices.
Remote control panels guarantee optimal comfort of operation, monitoring, maintenance and service. All
operations can be performed using remote panel, which displays the status of the system, fault reports
and service settings.
Features:
• Simple use;
• Surface mounted;
• 4.3 touch-screen;
• Display of functions and set points;
• Acoustic response to touch;
• Maximum fan speed setting for limited time period (BOOST);
• Blocking (locking) - protection from children;
• User menu for fan speed, mode, status, CO2 control settings.
Packageincludes:
• 1x Ptouch control panel;
• 1x Cable;
• 1x Manual;
• 2x Fastening elements (screw 3,9 x 25 DIN 7981 – 2 pcs nylon plug 5x25 – 2 pcs, hammered steel plug
12x30 – 2 pcs).

Ptouchinstallationonaplaster-boardwall:
1-2Turn over the panel. Use a screwdriver to lift the cover as shown in g.2.
3Take the cover apart.
4Put it at desired location on the wall. The arrow must point upwards. Mark the positions of mounting
holes (distance center-to-center is 106 ± 0.5 mm). Also mark the position of the square hole for the cable
(30 x 20 mm).
5Drill two 5 mm holes at the marked positions for nylon plugs and the hole throughout the wall to install
the cable. Insert the nylon plugs.
NOTE:Youcanusespecialmetalplugs(included)insteadofnylonones.
6Use included 2,9x16 DIN7981C screws and mount the panel to the wall as indicated in g. 6.
Connect the included cable to the panel and pass another end of the cable through the square hole in
the wall.
7-8Put the panel on the mounting bracket by aligning the upper identations. Then push the lower part
of the panel.
