Siemens TEC Point

[gazoo]

i have a hot water valve on a TEC that is set up invertly. 0% fully open, 100% fully closed. without physically switching wiring on controller can i change action via insight??

What application is the TEC using? Check the application point list. If you can change the action there will be a binary point to change the action. You should then be able to change the action from the Insight. You will need to back up the TEC to the panel and the panel to the Insight to make sure the changes are backed up and won't be reversed if the TEC loses power, this will cause a reload of the TEC point list in the panel.

What is the current value for point 58? This will help me find the value you want.

I can't find my old Insight CD's , I haven't worked for Siemens in a quite a while, but I was able to look up the application guide for VAV TEC's on the internet & point 58 is the point to change the action of the motors. Just remember it affects all 3 motors (VAV damper & both hot water valves). Unfortunately what I found on line didn't have the table for how the value works. Check your Insight CD's, I believe there should be a copy of all the application guides with the values for point 58 & how each value affects the motors.

It has been a few years for me but I think the DO Direct should be a value of four to accomplish your goal.

Don't hold my feet to the fire but I'm about 66% confident on this.

Thinking about this in the morning, I may have been thinking of the 2070 application, not the 2023.

Don't want to steer you wrong if I can help it.

You may have to do a wire reversal.
Hope this helps....

5 equals motor 1 is enabled, motor 2 is enabled and motor 3 is not used.
13 equals motor 1 is enabled, motor 2 is enabled and reversed, and motor 3 is not used.
