Hi all, firstly I’m not in anyway qualified to do any electrical work but was just hoping for a quick piece of help In regard to trying to find a replacement for my non-functioning Uponor PRT-E digital thermostat which controls our underfloor heating. The model in question, the PRT-E is generic to a number of different brands, and I’m struggling to find the identical Uponor model at a reasonable price to replace my current thermostat. I am however able to find an almost identical model, with one exception. The LOAD symbol on the sixth wiring input on the model that i was looking to purchase is different from the left arrow symbol (again sixth input) on my current version (Please see red circled screenshots below). My question being are these essentially the same, and therefore interchangeable and compatible with my existing system, or would i need a direct replacement for the model in the bottom screenshot, for the system to work in that zone. Many thanks in advance! Rob
