I thought about putting in a table reset as you mentioned of 60*=140, 30*=180 where OAT is referencing the HWS-T of the loop.

The controller is a DX9100 which I am not that familiar with. I am trying to review the program.
Sequence:
The hot water system consist of two hot water boilers each with a dedicated circulating...

Would it be recommended to program the following:
If OAT is below 36 degrees and secondary hot water supply temp is below 150 degrees for (period of time - example:15 minutes) then start boiler #2,...

I am new to this site but yes the lead boiler is what is enabled. I have not tried to to off boiler 1 to see if boiler 2 will start. Any thoughts on having the lag boiler "start" if the supply water...

I am currently working at a site that has 2 hot water boilers each with 3 way mixing valves for primary loop, dedicated primary boiler pumps and 2 secondary pumpsfor the secondary loop. The boilers...

I am currently working in a facility where they are using Metasys ADX server. There are 2 floors with about 100 VAV boxes that are Siemens TEC and they are connected into the Metasys which allows you...

I can use MAT for control. There is a MAT sensor, the MA low level setpoint is 45 degrees and the freezestat is set for 38 degrees. Yes, I can upload the program in HVAC PRO. Here are the parameters...

It is being controlled by the SAT.

It is the older AHU-101 controller. There are 2 points economizer available and economizer enable. In HVACPRO, the ECONSP = 57. When the outside air is below 57, the economizer available changes to...

Looking for some help on JCI Metasys. When AHU's startup, the OAD's go to 100% until about 2 minutes, then they slowly modulate to position they are trying to maintain. This is causing some AHU's to...

I just acquired a new site that has Trane Tracer Summit v17. The current building operator does not receive any alarms and does not know when something is in alarm until he goes to his workstation...

Thanks for your responses and my apologies for sounding harsh. You are correct in many areas such as I have had no support at this site at all. I did react quickly and for that I am sorry. I...

As for previous repsonse about calling in somebody who know what they are doing, I won't post on this site again. If you can't ask questions to get answers then this is a waste of time. Problem is I...

Just venting about no support from JCI whenever they do anything onsite. As the controls tech onsite, I have had to learn Metasys the hard way, trial and error. Learned alot the hard way but sure...

No problem. All I was trying to accomplish was to see how you backup the nae data with your laptop. We have 12 nae's and I was going to plug into each nae for backups. The JCI tech doesn't...

Just one NAE will be plugged in.
I was going to plug in directly to the NAE with my laptop to get a backup before upgrading the NAE. I thought that you needed a hub or switch in order to do the...

I would like to connect to a Metasys NAE-55 with my laptop. Is it better to use a hub or a switch. Can somebody provide a preferred product to purchase.

I just got a new laptop with windows 7. I previously had windows xp. I can,t login to a site remotely with windows 7. Do I need to update a newer java?

I have a Metasys server front end and the controller is a FEC2610. While looking on the front end, under and NAE, this FEC and its points are located.

I agree with your comment. I also have posted a few questions, did receive acouplemof responses, bu that was it. Not very helpful when looking for some direction.

The reason I am trying to rotate pumps on a monthly basis is due to the building maintenance not remembering to command the PMP-ROT point each month. I did try to create a simple control strategy in...

Thanks for your response. If I am understanding correctly, by answering the Q/A's and selecting the pump runtime rotation box, which I have, that the pumps will rotate on their own, based on lowest...

Sorry, meant to say above 200 hours, P6 (Off), P5 (On)

The program is CCT in a FEC2610 and I do see the pump totalization in output control for P5 and P6. On the front end (ADX) I am reading:
P1 runtime = 200 hours, (Pump 5-C, OFF)
P2 runtime = 114...

Trying to setup 2 pump points for totalization for rotation in Metasys.

Can someone help me to toggle a pump rotation point from false to true momentarliy to switch a pump command on in JCI. I am using an X<Y for rotation and have tried a timer and a latch for the output...

After looking around in CCT, I found out where to reset the runtime hours.

How do you map the hours into user views? I have gone to the controller, insert field point, assisted, invoke discovery but I don't see any hours point. Are the hours just being totaled by the HWP-S,...

When looking at the HWP-S point in the ADX, the elapsed active time shows alot of seconds. When I go to edit, I can't reset the active time reset.

I believe it is being done through the BI (HWP-S). I don't know how to check. When I am in CCT, I don't see a place in any of the points where the hours are being totalized.

Or do you have to do this in CCT, then downlaod the program again? I was talking about the command option on the ADX

When I right click on the point HWP6-RUNTIME I get default value, enable alarm, disable alarm, not reset option.

Does anybody know how to reset pump status point runtime hours to 0 in Metasys. There is no override option for the PMP-S point to reset. Can't find where to do this.

I could send you a snapshot in Word to show what I did yesterday to one of the HX's. I didn't do the programming is CCT but I created on the ADX in control strategies. I agree about JCI, their stuff...

If I sent you the.caf file would you be able to look at it.

No I am not that familiar, but if shown I will understand. I am have been working with controls for a long time, mainly Siemens, but for the past few years been cx a building with JCI using CCT and...

If on the workstation, click on the ADX or ADS icon in the site tree, select e-mail, advanced and then enter in the information for your email address.

I can read the totalization hours of each pump. The pumps do not shut off each day, they stay ON below 60 degrees based on an OAT reset schedule.
I think I can accomplish this part of programming in...

I did create a new TEST program similar to the one I am working on. I am trying to figure the points and connections. As I mentioned, the rotation does work manually by commanding the PUMP-ROT point....

No I haven't. I haven't spent alot of time with the CCT programming.
I would prefer the customer not messing with the lead lag. As for the program I am reviewing the CCT HWP program but I don't see...

This is for 1 heat exchanger and 2 primary heating pumps to be rotated on a monthly basis.

Just updated laptop to 5.1.0.4

Server is 4.0.0.3

FEC-2610 (using CCT)

Does anybody have sample lead/lag program with 2 pumps for Metasys they could share.

I am looking at a hot water system with 2 pumps that the customer would like to lead/lag the pumps each month automatically. Currently, to switch the pumps you have to toggle a PMP-ROT point to...

I sent you a copy of the .caf file for your review. I appreciate your help!
I can't get any from the JCI techs.

I would prefer the customer not messing with the lead lag. As for the program I am reviewing the CCT HWP program but I don't see the pumps rotating on hours. This is what I have:

HPW6A-C = OFF...

Is it possible to send me a copy of your lead lag program? I am trying to lead lag 2 hot water pumps based on hours (monthly). I would like to create this either in CCT or using the control strategy...

Can somebody send me a copy of this lead lag program. I am trying to build a lead lag program for 2 hot water pump that will switch monthly. I am not familiar enough with the block programming.
