apex to tunze cable extension?

drukkosz · Sep 19, 2023

After some research I couldn't find an answer to my question so here I am.

My apex is in my basement and my tunze pump is upstairs in my main display. I have 2 Channel Apex to Tunze Stream Cable but its very short and wont reach the pump. Is there any kind of extension i can use in order to control the pump through my apex?

Does anybody know if this cable would work?:

Profilux Tunze Connection Cable - Type 2

What does your current cable look like and where does it plug into your Apex?

Hi,

this is the cable, not sure why they made it so short. It has 1 RJ45 connector which plugs into the Apex base unit

It sounds like maybe all you need is a M-F RJ45 connection then?

This or a 5 pin din male to female.

Thank you for your responses. Now I have a idea what to look for. I was wondering, is there a reason why not try the cable from profilux?

Did you ever find a solution to this?

I am working on the same issue and wondering if a regular cat 6 extension cable with the Rj45 Male & Female ends will work to extend the cable.

unfortunately I have not. I had to mount my apex unit very high in order for it to reach it...
