GF Conical Pro Test 30.12.22 - 02.01.23

• Already washed when fetching it - november 2022
• Rinsed / sprayed with Star San and let dry

• Filled with 21 L water
• Setup Wi-Fi OK
• Measured:
  • Device: 30.12.22 16:56: 21.2 C
  • Digital Inkbird (top) - broken 26 C
  • Analog Temp (top) - hard to read - 20.8 C?
  • Analog Temp (middle) - 20.2 C?
• Might be 0.5 C off - OK
• Note - no insulation of any kind

• Set point 25 C (already heating from factory preset) - 30.12.22 16:56
• Set point 23 C - 30.12.22 17:47
• Reached 23 C - 30.12.22 19:14

• Filled 5 L mug with about 4.5 L + a bottle of frozen water and placed in keezer
• Did not drill holes yet - so lid a little bit open in keezer
• Measured cooling water temp with analog - 7 C 30.12.22. 17:30
• Set point 15 C - 30.12.22 19:25
• Quite big leakages - presumably from quick connect fittings- had to tighten with wrench very hard
• Added "gjengeteip", resume cooling - reading 20.1 C - 30.12.22 19:50
• Cooling water 11 C, reading 18.1 C - 30.12.22 23:31
• Cooling water 14 C, reading 15.8 C - 31.12.22 12:45
• Set point 16 C to check if temp can be maintained - see that GF goes into monitoring state
• Added half-frozen water bottle to water mug, reading 16.3 C - 31.12.22 16:38
• Set point 12 C
• Set point 14 C - 31.12.22 ??
• Reading 14.1 C - put bottle into freezer 01.01.23 12:03
• Put frozen bottle and 0.5 L cold tap water - reading 14.2 C - 01.01.23 16:40
• Set point 12 C
• Seem to be struggling - reading at 12.9 - 01.01.23 21:22
• Set point 13 C, removed water bottle
• Still struggling, set point 14 C - reading 13.8 C? at 02.01.23 07:35?
• Seem to be keeping 14 C OK - cooling water about 9 C, reading 14.2 C at 02.01.23 19:40

• Unplugged adapter, disconnected wire to fermenter, closed fermenter inlet with cap
• Tried to use Ryobi air compressor to blow out air, did not get everything out - but most of it. About 0.8 L water in hoses and fermenter
• Drain water through outlet valve and last bit through dump valve
• Quick rinse with hose
• Will spray with Star San when air-dried

• Blue circles when adding frozen bottle and changing set points

• Need frozen bottles in order to bring temp down sufficiently - use 2 and rotate is probably a good idea
• Very hard to push temperature down by several degrees at once without very cold water
• Quite efficient at keeping the temp once reached
• Hysteresis hard-coded at 0.5 C
• Should work fine to keep pitch temp and rise afterwards, will not work great with Cold Crash...
