Document Number 671703 The EMC Directive 2014/30/EU The Low Voltage Directive 2014/35/EU MRXBOX-VSC Visual System User Control Installation and Maintenance 1.0 INTRODUCTION The MRXBOX-VSC is a user control from the Ecosmart range. These wall mounted user controls include a 3.5’’ colour LCD touchscreen display to provide improved user interface. The unit can be surface or semi-recessed mounted and is compatible with standard 2-gang recess back box. The control is manufactured from an all plastic construction and supplied with 10m of pre-plugged connection cable and surface mounting back box. Units are SELV (12 Vdc) with the power supplied from the fan unit via the pre-plugged cable. 2.0 DIMENSIONS 3.0 INSTALLATION The unit is supplied with back box suitable for surface mounting (see Figure 2 - Figure 6). If semi-recess (final projection from wall is approximately 7mm) is needed, a proprietary 2-gang back box (25mm deep minimum) may be used. Always physically check the suitability of the back box before fitting. In some instances, the earthing point of the back box may foul the unit and need to be removed. 1. Fix one end of the 10m cable to the fan’s Ecosmart connection point and route the cable to the mounting position.

The mounting surface must be free from vibration. 2. Unclip the front bezel from the unit and remove the 2 retaining screws, then remove the working section from the back box (see figure Figure 3). 3. Feed the cable through the knock-out hole in the base of the back box and mark the fixing point on the wall, drill appropriately sized holes at the required fixing points and insert the wall plugs. Fix the back box on to the wall (see figure Figure 4). 4. Plug the data cable into the socket (see figure Figure 5). 5. Fix the unit back into the back box using the screws supplied, then clip the bezel back on the unit again noting which way is up.

They have a 3.5in colour LCD touchscreen display to provide improved user interface. The unit can be surface or semi-recessed mounted and is compatible with standard 2-gang recess back box. MRXBOX-VSC– the unit is all plastic construction and supplied with 10m of pre-plugged connection cable and surface mounting back box. The units are SELV (12V d.c.) with the power supplied from the fan unit via the pre-plugged cable. 1.0 Installation INSTALLED ENVIRONMENT 0-40oC and up to 90% RH non-condensing. Caution: The unit must be installed away from any direct source of heat (e.g. radiators) and not in areas where it would be subjected to steam or water spray. The mounting surface must be free from vibration. The unit is supplied with back box suitable for surface mounting. (see Figs. 1 - 5). If semi-recess (final projection from wall is 7mm approx) is needed, a proprietary 2-gang back box (25mm deep min.) may be used. Always physically check the suitability of the back box before fitting. In some instances, the earthing point of the back box may foul the unit and need to be removed. a) Fix one end of the 10m cable to the fan’s Ecosmart connection point and route the cable to the mounting position. b) Unclip the front bezel from the unit and remove the 2 retaining screws, then remove the working section from the back box. (see Fig. 2). c) Feed the cable through the knock-out hole in the base of the back box and mark the fixing point on the wall. Drill appropriately sized holes at the fixing points and insert the wall plugs. Fix the back box on to the wall. (see Fig 3). d) Plug the data cable into the socket. (see Fig. 4). e) Fix the unit back into the back box using the screws supplied, then clip the bezel back on the unit again noting which way is up. (Top is printed on the inside face of the bezel and and middle section). (see Fig. 5). 2.0 Data Cable Installation A 4-core SELV data cable is used to connect the control to the fan. Do not run data cable in the same conduit as the mains cables and ensure there is a 50mm separation between the data cable and other cables. For cable lengths in excess of 10m a MRXBOX-JB will be required to provide sufficient power. Keep the number of cable joints to a minimum to ensure the best data transmission efficiency between devices.
