thought you mentioned got one shop along jalan besar rd ...at the beginning of the road ( coming form bendeemer rd)..... if not try sim lim tower at the top level got sell ... biggest shop next to the escalator .... lady boss ... very friendly and nice and helpful lady... think she offered the unit for 60 bucks ... dunno if the probe is included ....

i thinking of getting one .... but dunno how to connect it the chiller ... spade, have you done it before ? can help ?... i was thinking of DIY 1 such that the controller is connected to a switch( power point ) that the chiller is plug into and turns the chiller on that way ...and not changing the internal circuitries of the chiller itself ... you know how to do it ?

for eliwell one i've the connection diagram. i can pass u if u want (at home, now drifting at work ). it's pretty simple. dun think eliwell is good cos it break for no reason ....

anyone got a better one to recommend?

[spiff]

spade, break for no reason???? wat u mean by tt?

[mv3i]

but is yours connected str to the chiller ?? I was thinking of modifying it such that it becomes a 3 pin plug and the chiller is plugged into it and the controller turns the chiller on via the plug .... ( er .... seems rather chim !!! how can help ?? )

the chiller cooled down to 27, stopped. waited a long while temp goes up to 29, when it start, a loud sound and everything stop.

later opened up the whole chiller and test here and there find out that only this thing is not working. is this normal with other chiller also??

this controller is connected directly to the chiller's compressor and probe. 4-wires only

i really dunno man. it doesnt hv control any more. can start but cannot stop. when the temp of the water is higher then the temp set, the controller displays "hea" which i hv no idea wat it means.

my fren sold me the eliwell.

spade tt means ur chiller is 2nd hand lah, n u hv no idea how long the previous owner used the eliwell??

spade ,

saw the manual on your temp controller ....

something to ask you ...

saw under wiring :

12 ... NO ... means normally open

13 ... NC ... means normally close ...

but how to connect and to what ?? ? ???

the rest are pretty straight forward with the power supply and probe attachment wire .....

12 ... NO ... means normally open

13 ... NC ... means normally close ...

u should connect to 1 and 3, meaning it will only on when the temp reach the setpoint+differential (normally set to 2deg)

if u connect to 1 and 2, it will always on. no relay.

Spade, so now your chiller is operational based on direct water temp??? meaning your probe is in your sump rather than in your chiller???

BTW, how did you ever understand all those technical specs????

I want one too........!!!!!!!!!!!
