Hello, I'm Scott from WarmlyYours, and today we're going to discuss the low voltage connections between our SCP-120 controller and the aerial sensor and slab sensor. This guide will help you understand where to make these connections to ensure your system operates correctly.
In this setup, we have our controller, along with the in-slab sensor, which continuously monitors the temperature of the slab, and the aerial sensor, which detects the air temperature and snowfall. To make the necessary connections in the controller, you'll need to open the front cover. You'll notice that we have already removed some screws, but there are additional screws that will need to be taken out. Additionally, you will need to pop the plastic rivet located on the front to fully remove the cover.
Once the front cover is off, you'll see where the connections will be made. We have removed the metal bracket from the box to make it easier for you to see the connection points. The connections we will focus on are located along the terminal strip, which is numbered for your convenience. Specifically, we will be connecting to screws number 1, 2, and 3, as well as screws number 10 and 11, which correspond to the aerial snow sensor and the in-slab temperature sensor.
Looking at the wiring terminal strip, terminals 1, 2, and 3 must be connected in a specific order: white wire in terminal 1, black wire in terminal 2, and red wire in terminal 3. For terminals 10 and 11, the color of the wires does not matter, so you can use black or red interchangeably. The key is to ensure a solid connection between terminals 10 and 11.
When making these connections, it's important to minimize the amount of excess wire hanging out to prevent any chance of short circuits if the wires happen to cross inside the controller. The wiring space can be tight, so aim to keep the insulation close to the terminal connections. These connections are simple screw-down types, and a small screwdriver, such as a jeweler's screwdriver, will suffice for this task.
That's how easy it is to make your low voltage sensor connections with the SCP-120. If you have any further questions, feel free to contact us at www.warmlyyours.com.
