 PID REX C100 (REX-C100FK02-V * AN or REX-C100FK02-V * DN) Component Needed (this or XMT 7100) Cheaper, the set comes with SSR (it is possible to use the thermocouple but I recommend to buy another model). For other details, check the comments about the XMT 7100 below. Check the spec: the models linked are FK02, not FK07. 9.00  PID XMT 7100 Component Needed (this or Rex C100) Some people prefer this design, the smaller size. However, you need to input a code even to change the target temperature. With Rex C100, you just press a button, and can see the target and current temperature, but it's a bigger device. 40.00  SSR Component Needed (except if you buy the PID kit above) Pay attention to the spec: 40A, 24-380 VAC, 3-32 VDC 4.00  Termocouple type K (hole washer model) Component Needed You can also buy the PT100, but this is good enough. The reason for this model is that it's easier to fit under the thermostat that you will bypass.
2.00  Piggyback connectors 6.3 mm Component Recommended 1.00  Wires Component Needed Recommend at least AWG16 which is adequate for up to 13 Amp 13.00 (4 colors, 5 meters each)  Wago Connector Component Recommended Be careful with similar / counterfeits 6.00 (pack with 10)  Connectors kit (without piggyback) Component Recommended 8.00  Thermal Compound Paste Consumable Highly recommended There are cheaper versions, but this one has a higher heat transfer capacity. 7.00  Thermometer Tool Optional Useful to measure the temperature in the puck which tends to be 10-15 degrees below the boiler. If you don't want to buy, I recommend to adjust the offset to -12 in your PID. 5.00  Crimper and Cable Cutter (Model Pro) Tool Optional 10.00  Multimeter Tool Needed 8.00  Multibits toolkit Tool Optional 20.00  Aluminium Enclosure for XMT 7100 Component Optional You can use a 3d printed version. There are enclosures for PID, Dimmer and Pressure gauge integrated for Gaggias and I will design one for Rancilio SIlvia and make it available on https://makerworld.com/en/@espressohackers 10.00 |
