New 6105 on Apex Question

GQuinn · 03/22/2018, 10:30 AM

What is the minimum flow setting on the Apex for the new style Tunze 6105? The old style 6105 were 30%(min) or 0%(off). I thought I read somewhere the minimum % was different.

Thank you

The pump can do 20% now, but keep in mind, to my knowledge Apex is still using the old control voltage range so the speeds are not correct. What you will usually find is 40% equals 20% and below that the pump will stop.

So if 40%(apex) equals 20% (6105). Is 100% the same on both?

Thanks again for your help.

Roughly, the top end does not matter 6.5-10V is the same as 6.5V, the problem is the bottom range is all compressed so the voltages don't match up.

Thanks for your help. Just to verify, when using the Apex for control, the dials on the 6105 controller have no function.

Yes, they should be set to external and main speed to 100%, after that it is ignored and the Apex will control it.
