Compressor delay setting on temp controller

[fun4stuff]

what do you guys have your compressor delay set to?

I have it set to 3 minutes on my STC-1000. IIRC, that's the default delay time on the unit and I just left it that way. Just long enough to keep the freezer from toggling on and off a lot.

Edit: it's for a ferm chamber, not a keezer. But the principle is the same.

Same here, 3 minutes. On two ferm chambers, a keezer, and a glycol chiller.

Mine is at 5 I believe

I use an Inkbird 308 on a full size GE fridge for fermentation/cold crashing, etc. I have another 308 on a 4.4 fridge for smaller scale and lagering/aging. I set both to 4 over under on alarms, 2 over under on temp set point and 5 on compressor delay. They dont cycle often since they both are pretty efficient.

My controller instructions say this:

“The Anti-short is the delay time to turn on the cooling device. If the cooling device is compressor based, compressor should not be turned on immediately when it is at high pressure (just after turned off). Otherwise, it may shorten the life of compressor. The Anti-Short cycle delay function can be used to prevent the rapid cycling of the compressor. It establishes the minimum time that the compressor remains off (after reaching cutout) before turns on again. The delay overrides any controller demand and does not allow the compressor to turn on until the set time-delay value has elapsed. It gives time to release the refrigerant pressure through evaporator. It typically set to 4- 6 (minutes). The unit is in minutes.”

5 minutes.

More importantly, if you aren't using a thermowell put the probe against the fermenter and put some insulation over the probe to make sure it's reading the beer temperature and not the air temperature.
I tape on the probe and then tape a sponge over it.

Thanks guys! My fridge is already on the fritz. I think I’ll be on the conservative end and set it to 5 mins then.

I use an STC-1000 and I set the compressor delay to whatever the maximum is... it's been so long I can't remember what it is, but I think it's 10 minutes. I figure, any temperature change on a large vessel of liquid is going to be negligible over an extra few minutes so might as well crank up the delay and minimize compressor cycling as much as possible. In practice, assuming an undisturbed chamber, I realize setting it at 10 minutes probably yields the same cycling schedule as 5 minutes, but whatever.
