Carel HecU and RHEC Manager I Have No Idea But Let's Go Through IT Together Episode 529

Carel HECO/pRack Simulator Chaos: CO₂ Store Startup, Firmware Headaches & High-Pressure Valve Settings

In this episode of the Advanced Refrigeration Podcast, hosts Brett Wetsel and Kevin Kompus roast the brutal heat and then jump into a messy CO₂ startup at a Jewel-Osco—made worse by electricians missing neutrals on case circuits. From there, they wander into hands-on “FAFO” mode using Carel’s RHEC Manager to simulate HECO/pRack controllers, repeatedly running into freezes, blank screens, and the key gotcha: you can’t open or simulate a program unless the firmware version and required binary/CT-CD files match, and the firmware isn’t visible inside the downloaded variable list. They poke through CO₂ transcritical menus (HPV/receiver/flash tank pressures, valve behaviors, safeties), discuss tuning KP/KI on a pulse-width valve to stop it from slamming shut, and complain about proprietary MultiMAX/Pico programming, limited support, and confusing compressor staging logic, teasing a follow-up on laptop connections and navigation.

Dorin Compressor Software What Can I Use It For & Brett Gets A TOOF Episode 529

Dorin CO₂ App Walkthrough + Heatwave Rack Chaos (Advanced Refrigeration Podcast)

Brett Wetzel and Kevin Compass open with jokes about Brett’s new tooth causing a lisp before diving into brutal Chicagoland heat (95°F+ for two weeks) and how it’s hammering CO₂ racks, especially systems without adiabatics. Kevin describes racks struggling at peak hours, capacity gaps where a second compressor is too large, VFDs stuck at minimum, low suction, rising discharge temps, overload trips, and heavy flash gas with bypass valves 50–60% open, with gas cooler outlet temps around 97–98°F (near ambient). They discuss limited quick fixes, defrost scheduling problems, and controller wiring/programming hurdles. Brett then screen-shares a training-style walkthrough of the Dorin app for sizing and troubleshooting, entering typical inputs to estimate compressor selection, discharge temperature, amperage, and using those values diagnostically to spot issues like valve plate blow-by rather than relying on pump-down tests.

Fishing Fails, Target Startup Nightmares & Chicago Fireman’s Dump Lines | Advanced Refrigeration Podcast

Brett Wetzel and Kevin Compass open with fishing stories and then jump into a rough Target CO2 startup plagued by miswired comm loops, mixed case-control hardware, and constant walking in a multi-level downtown layout. They discuss troubleshooting methods for crisscrossed MODbus wiring, common causes of shorts and opens, and an electrician mistake that blew an XM controller apart. The hosts explain Chicago’s “fireman’s dump line” code requirement and how piping it off the bottom of a suction header can trap oil and cause recurring low-oil issues. They also flag a backwards high-pressure control/relay setup on a Target backup CO2 unit, share practical tips for S3C/Corelink/CC200 case controllers, Ethernet jumpers, termination, protecting solid-state outputs, transducer orientation, and water-damaged controllers from case washing.

E3, Pack Controller, I Pro, O my Brett Looks Like He’s From Arkansas!! Episode 527

Post-Anesthesia Tech Tips: iPRO V5 ADF File Failures, Valve Driver Mix-Ups & Danfoss Tunneling Gotchas

Brett and Kevin kick off the Advanced Refrigeration Podcast with Brett fresh out of oral surgery and sounding “absolutely hammered,” then pivot into startup tips for new CO₂ racks using E3/E2 controllers with iPROs. They warn that many OEM programs load the wrong ADF files—using iPRO CO2 instead of the iPRO V5 ADF—causing pressures/temps to read correctly while the HPV stays at 0% and won’t open, potentially high-heading and shutting the rack down; the fix involves deleting old ADF files and fully reprogramming the application. They also cover common configuration mistakes like valve steps being “x10,” assigning valves to the wrong drivers on V5 dual-driver setups, verifying peak/holding current and step rates for Danfoss valves, checking swapped T1/T2 sensors, and adding backup network P/T sensors for redundancy. Finally, they describe Danfoss PAC/System Manager tunneling being disabled after about eight hours for security, a Danfoss controller IP-address glitch that may require toggling HTTPS/DHCP or reloading the program, and the importance of correct HTTP vs HTTPS ports when connecting remotely.

Target Startup Chaos, Buggy CoreLinks, andDanfoss EKE400/ICAD Headaches | Advanced Refrigeration Podcast

Brett and Kevin open the AdvancedRefrigeration Podcast after a brutal week, with Brett stuck on a transcritical Kevinwith a  startup at a poorly designed downtown store wherethe E3 and roof access are far from the grocery and the rack is on the roof. Heblames electricians for mis-marked and mixed-up comm lines, missingcontrol-power splices, and dangerous live voltages, turning a “simple” startupinto days of rework. They also vent about painfully slow, buggy CoreLinksetup and web UI issues compared to smoother E3 terminal mode. Kevin then walksthrough using a Danfoss EKE400 in CoolConfig for defrost and reheat control, MMRGdisplay jumper/address quirks, Modbus connection ideas, and generating wiringdiagrams. They finish with ICAD failures, O-ring moisture/rust problems, andsolving calibration alarms via process-of-elimination part swapping.

Skills Canada Gold, Rack Life inNewfoundland, and the Great Apprenticeship Debate |

Advanced Refrigeration Podcast In this episode of the Advanced Refrigeration Podcast, hosts Brett Wetzel and Kevin Compass welcome Devon Owens from Newfoundland, a three-time Skills Canada gold medalist, to talk shop andtrade some laughs. Devon breaks down Skills Canada—provincials, nationals, and worlds—plus the intense 15-hour two-day refrigeration build he finished as theonly competitor, featuring a two-evaporator, two-temperature system with EPRs, solenoids, transducers, a superheat controller, and an EEV. The conversationshifts to how Canadian apprenticeship schooling differs from U.S. union training, including unpaid full-time pre- eployment, block exams, pay-scale progression, and a challenging 125-question journeyman exam that spans everything from CO2 and ammonia to natural gas. They also touch on rack work,CO2 sites in Newfoundland, 600V power, and why water leaks can ruin your day.
