STC1000 Thermostat Case with BTICINO MATIX Socket

cults3d

This enclosure has been designed in order to have a more efficient and easy to use docking structure for the well known STC1000 Thermostat. There are many enclosures available for this thermostat, but all of them are just "shells" to protect the thermostat, leaving all the wiring out of the box. I wanted an easier and elegant solution, *something that could be considered *"plug-and-play" ** where the protective function is not the only focus. Hence I designed the "STC1000 BTM CASE", having in mind simplicity of use and a reasonably low budget to fully assemble it. (let's be honest, many of us are choosing the STC1000 for home-made projects where we want something functional while keeping the costs low.) Probably this particular case won't be of much use to users outside Italy due to the electric sockets used for the design; I don't know if BTCINO sockets are used elsewhere and if so whether the MATIX series is known. The case has two "snap-in holes" designed to accommodate two 16A BTCINO MATIX Sockets, which are the most commonly used and also the least expensive of the series available while still offering good durability and affordability. The "snap-in" design has been created in order to mimic the 503SA Wall Mount locking system, allowing a solid interlocking between the socket and the printed part. Differently from the native mount system, here it's not present the flexible tab used for the easy release of the item since there was no intention to create a variable system. Once locked in place the two sockets become pretty sturdy and can withstand the usual amount of force needed for plugging and unplugging. For this same reason, inserting the sockets will require a bit of pressure in order to slide over the locking pin designed in a recess of the wall. The base wall has a quite ample ventilation grid that won't require support. Since there are many sub-variations of the STC1000 module (some wider, some thinner) the slot is designed with ~2.5mm tolerance. The shelf item is provided to accomplish both the needs to securely lock in place the thermostat without using glue or zip ties and rationalize the space creating a usable pocket on top of it. (cables or temp sensor might be stored there) For further optimization, you can print a second shelf and further optimize the space on top of the thermostat. (such space was a due consequence of the height required for the walls in order to securely fit the MATIX Sockets) Neither of the shelves reaches the bottom, leaving an adequate space for the wiring. On the back wall, a generous round hole allows for passing up to two sensor cables, in case you need to use both heating and cooling control. Warning: do not attempt any electrical work if you don't have a full understanding of the process, of the safety measures and of the risks involved. Wiring an STC1000 requires dealing with live voltage, always seek the advice of an appropriately qualified professional.
