[au] Where can I get a anti-short cycle timer?

[paul_h]

Last job today was a quick look at a temperzone ducted split.
The timer had crapped itself.
I mainly work on electronic splits, not mech ones, so I don't have manuals or parts supplier for temperzone.
Anyone know who sells parts in perth, talking about these things that TZ and carrier normally use in this PDF:
http://www.mjbcontrols.com.au/manuals/lt240x300T.pdf

I need one quickly tomorrow morning.
I know of airskill, as I've bought controllers and more specialised temperzone stuff there, but they're a bit out of the way for me. I'm hoping a more generic parts supplier with more locations around the place stock similar timers, as I've said, I've seen these timers in nearly every non fully electronic a/c here.

Heatcraft, Actrol & NHP are my suggestions. Any of these stores nere you?

[paul_h]

Yeah, I've already looked through catalogues at actrol, airefrig, heatcraft, RS spares etc, it's not something those type of places seem to stock.

Both Actrol and RES stock those timers up here. Actrol part numbers are 155071 and 155077 Avion timers depending if you want an adjustable timer or not.

Thanks a lot, I was searching for the manufacturer name or model number, didn't know actrol have them under a different make/model.

Edit: wait, which one is the 3 or 4 terminal versions out of those actrol ones? ie like the one in the PDF I linked from another manufacturer.

I tried to follow the links to enerstat and avion, but still none the wiser for it

These are just basic anti short cycling timers put in line with the the compressor contactor. I don't have a temperzone wiring diagram so not sure what the other two terminals are for on your timer.

crazy things are happening here, when I posted, I got redirected to a website called mettical?

Well I can help there:

It just means the hp/lp goes through the seperate timer circuit, rather than the compressor contactor circuit.
Not a big deal, I just don't really have time to stuff around rewiring the control circuit. I'd rather chuck the same timer in and be done with it.

Edit: btw, the diagrams in that link are not right. This one has reverse cycle and a de-ice pcb like the last diagram, but has the time delay relay (unlike the last diagram) same as the first cooling only diagram

Sorry buddy thats all I got at the momment. There a nice and simple timer and no neutral is required. Normaly just bypass the timer untill we can get another.

If you were to bypass yours you would just have to join numbers 1 to 3 and 4 to 2 till you get an original, or put the new timer in 1 to 3 and join 4 to 2.

Thanks for your help anyway. I know where I can get temperzone parts, like I said, it's just that they were a fair way away.
I've already bypassed the timer for now, I did that on friday after not having found anything straight away/getting any replies here.
Now I can leave that job alone for a few days anyway as the weather has cooled here. I'll order one from airskill and hopefully get back to it on wednesday.

I have had a problem where the time delay for the compressor start was taken through the pcb, and had stopped working, not letting the signal through to the comp contactor. My solution was to take the input signal and wire it through a delay on make timer, fortunately the defrost etc was controlled seperatly.
