Temperature Controller

[BarraCudaTM]

just to inform you all .. the EWPC 901/N is the older version of PC901N

Oh,..... you are refering to the external probe......

but isn't that how chillers work???

and how does the hysteris work in this area???

isn't the hysteris the difference between the wanted temp and the activation temp...

If that is so..... think the external controller should have that...

meaning, correct me if I'm wrong..... setting my reef temp at 27 C and the hysteris at 1 C.....which would cause the chiller to activate at 28 C only and stop its cooling function at 27C.....

think my braincells finally working......

BTW Hon, if you read this.... can you post up the settings (the P1, P2 thingy) for Teco Chillers again.....

I sort of lost track........ still trying to recover from the " shock " this morning......

phang .. you cannot set the differential at 1 degrees C

the PC 901 model spade is using have a accuracy up to 0.15 degrees C!

you need to set at least 2 degrees C to prevent frequent starting of compressor

btw both controllers can directly start compressors up to ½HP or can act as a relay for up to ~1900watts (240V * 8A)

Barra, that also depends on the chillers ability to cool the reef.... mines barely keeping it at 28C once activated even through the hysterisis is at 1.......once start never stop.... only after the lights went out.... and even then, takes awhile before it reaches its intended temp....

phang ,

that's becos u have about 800W of lights .... + pumps + water +LR + corals to cool ...... the lights and pumps would be a killer for the chiller .... so wat chiller r u looking at next ???

[spade]

that's becos u have about 800W of lights ....

correction:

1x 250w + 2x 400w = 1050w!

[Phang]

Stop it... you too guys.... else I will zap you with the notorious Saki Ray.......

<_<

[mv3i]

wah .... even more .... gosh .... think he needs at least a 1.5HP chiller for that tank size and lights ... wat do you think ??

DIY chiller or install industrial cooling fans

Barra,

If you are available one of these days, maybe can come over and have a good look.... the last round was busy with reef refurnishing so couldn't sit and troubleshoot.....

then see if some ammendments made should improve in the heat reducing of my reef....

And yes, would need lots of help with MHs (downgrading to 250W) and the introduction of the temp controller to mine system........

[mv3i]

bought the probe but it doesn;t work with my temperature controller .... so anyone wants to use it to try on his chiller ???

<_<

[spade]

the controller can't read from the probe?? do u need to change the probe type in the controller??

maybe weekends but this week I got stuff to do

btw , how to change probe type in the controller .... ???

note : ... i only bought the probe from them and not the controller ... and the controller is reading 50 on the display when i replaced the probe ....

Is there a way to change the probe type , spade ???

[spade]

the eliwell supported 2 type of probe, PTC and NTC. the problem now is what type of controller u r attaching it onto? i think tanzy posted some Teco programming b4, but can't seems to find it ... need to verufy whether they can support the probe ..
