FX Controllers w/TEC 1100 & 2100 Series - HELP!

[esusa56]

We're running into some difficulty with the FX controllers (retrofit of NCM350) when connecting to the JCI TEC 1100 and 2100 series programmable t-stats. Specifically we are having an issue with not being able to remove some over rides from the local user (ie unoccupied setpoints). These are connected to a building with WSHP and when someone screws with the t-stat after hours it can lock out the unit as the condenser water systems are not on. We also have an after hours system to manage after hours requests. Is there a dip switch or lock out setting for these pieces of #$%&?

:mad:

Depending on the model, you have the ability to "Lock" the buttons on the TEC T-Stat, it's different on almost all of them.

A word of caution (if your using FX-20/40/60) do NOT use the setpoint command for those babies (the TEC's I mean). It will cause you no end of grief. JCI documnets in the new lit to use either Override or Emergency Override only. If you can get to the JCI website (http://cgproducts.johnsoncontrols.com/default.aspx?main.aspx&2 ) search for the model number(s) of the TEC's you are dealing with to the the cut
sheets.

Good Luck,

Thanks.

Why are the setpoints an issue?

:confused:

The TEC's are not JCI OEM, they will accept a "setpoint" command but usually go into fault, then you have to go to the proberty sheet and mess with fallback as null, not null, null again to remove the setpoint value.

If you can't find the TEC1100 documentation I may have it in pdf somewhere.

thanks.

I would love any TEC1100 documentation that you have.

My email is in my profile.

Did you try the link I sent ? Give it a shot, there is tons of Johnson literature available. The TEC1100 is a bit hard to find but I'll email what I have.

[esusa56]

Yes I have been there and have downloaded all of the 2100 series docs. We do have an 1100 series doc, but I wanted to see if there is anything available that we may have missed or do not have.

Thanks for your replies.
