That's well done. Cable is the correct type (LIYCY = 2x stranded copper wires + copper braid shield). The zip tie holds the cable itself, there is no ...
+1 CAT5 and 6 work absolutely fine for RS485 until the wires break, which will happen eventually if vibration is present or someone opens the panel ...
Heat of vaporization of water is 2.25 MJ/kg (0.625 kWh/kg), this is the amount of heat that must be removed to condense 1kg (or 1l) of water. Dehumidi...

Well deserved! 👌 55°C to the rads is really high, shouldn't be that high if they are oversized. Assuming the heat loss is correct, this shou...
OK Power (Watts) = Flow (in l/s) * Heat capacity of water (4180 J/°C/L) * DeltaT (in °C) Flow (in l/s) = Power (Watts) /( DeltaT (in °C) * Heat ca...
Heat capacity of water is 4180 J/(°C.liter), therefore 1kW = 0.24 °C.liter/s Assuming inlet water temperature 20°C outlet 65°C deltaT 45°C, 1kW cool...
Above dew point cooling is mostly useless. For actual air conditioning you need both cooling and dehumidification which can only be achieved with belo...
If it is RS485 (is it?)... It uses balanced/differential twisted pair link. The idea is to send the signal on one wire, and the inverted signal on t...
