FX40 help...

[smokeout]

I have a facility that has multiple VMA's in a public area, the customer wants the stats locked down. I know how to do this with HVACPro, is there a way to do this through the FX? Or do I have to change in HvacPro, save, and change prn? (nightmare) Can I delete read point add rwpoint for acthtgsp and actclg sp without ill effects?

Just bring in the warm/cool adjust or remote setpoint ai as a numeric writable and you can override to your heart's content

Brought WCADJ in and it is showing fault. It is not giving me a fault cause. Do you know the name of the remote setpoint point?

I took COMMONSP to 0.0 and added values for CSP and HSP. I dont think I have seen a point for remote sp.


WC-ADJ and remote are the same point.

What type of stat is it (digital or slide adjust type)? And are the VMAs N2 or lon?

1-slide

2-N2

We don't currently have any FX40 sites where the customer desired to override the setpoint adjust so the points are mapped in as non-writeable. In NCMs and NAEs though we have customers that do this and it works fine.

So i would think that mapping AI2 as a numeric writeable should allow you to override it from the FX40.

WC-ADJ was reading fault because it was at -5 and I guess at lowest setting.
Overrode point to 0.0 and took CommonSp to 0.0 deg and set CSP and HSP and then it allowed ActSP to be presented. I think I got it. If anyone has a better way, gimme a shout. Thanks.
