Teco tk chiller temp reading issues

Piece of reef · Dec 12, 2022

Hey guys i have a teco tk500 chiller, and for some reason the temp plays up,
For example for about 1 hour or 2 hours it will match my inkbirds temp

Then randomly it will show 23c then 20c then go back up to 24c etc

Just rapidly going up and down, could it be the probe or thermostat display? If anyone has had it happen to them aswell would appreciate your answer

Assure the probe is an area of low flow and not near heater or return pump which can throw readings off

The probes inside the chiller, and the inlet is in the overflow section if the sump (first section), the outlet is in the return pump section,

Its strange because its been on for 5 hours now and hasnt played up

Ahh yes- you have the 500. I have the 1000 with external probe.
You may have to do an offset with higher/lower temperature to see if it changes into range desired
