I do not understand the assembly of Cross Manifold and Tekmar as a system.

Harold

I have a long thread in a post but I am starting a new one to help me communicate.

My incentive to work harder: The contractor is gone. I do not understand the information left behind. I have had no heat in the house for a month. Currently 55 degrees.

The intended build has stopped me because I do not understand what is remaining.

There is the original Tekmar. Has run just fine for a long time. Has three sets of 6 wires and a bunch of thermostats. Wires for all the thermostats are in the Tekmar. I think at least one of 6 wires may be altered. Not sure.

The Cross Manifold equipment has me more confused and I am scared to put the pieces together because I do not understand. I can easily destroy the equipment.

Note: I have no functioning photos. My camera has been broken by Microsoft.

The Tekmar is in the basement with the boiler. The primary issue there is that the contractor may have changed something. I do not think so but?

There are two closets upstairs (East and West). One has a single Cross Manifold and the other has two. I do not even know if the Cross Manifold is still in business.

In each closet there is a cable which has been placed by the contractor for existing Tekmar wires. There are 6 colored wires in each set of three. These wires are intended to interact with the Cross Manifold connections. I believe one connection can occur with others. Not at all sure.

The Cross Manifold is where I loose my understanding.

There is the required 24 VAC power to run the Cross Manifold board.

There are sets of interfaces for the Cross Manifold boards. They interact with the CM boards. Each set has three possible uses. Red, White, and C. The CM appears to have no use for the C item in each slot of interest.

Red seems to be a power link. But I am not sure what it does. I do not understand. The information is very limited. One approach I have made up would put a red wire for all the items in the controller. This is not the minimal use. Then use the white wires to distribute something. One approach seems to have wires distributed for each red wire - but that is not actually used from the limited information. It would also seem to prevent rational multi-wiring.

This is where everything goes sideways. Here is where I seriously need assistance. The Tekmar and the CM are seriously confusing me.

Please provide some explanations.

Here's the link to Cross Manifold.

If you can post some model #s of the Tekmar and the manifolds maybe we can help

Well, that's nifty.

This one has been a marathon session. This is more information than was previously provided.

1. How many 369's do you have?
   
2. How many t-stats are connected to each 369?
   
3. How many manifolds are in the East closet? How many valves are on those manifold(s)
   
4. How many manifolds are in the West closet? How many valves are on those manifold(s)
   

If you have questions on how to answer these questions, please ask.

Zman. I am still trying to get heat. 18 degrees today then it will get cold. I have tried a couple of contractors but they were reluctant to get the combination of things the way they are. I have a BOSH boiler, the Tekmar stuff, and the Cross Controls.

A person on this site has been extremely helpful. But when I get to the end of the day, I am just as confused as always. I used to be able to do most everything, but I am just too old to deal with this any more. I read and listen, and a minute later forget.

You have mentioned linking to the boiler from the Tekmar connections. There is one pair from the Tekmar to the DHW. That is working fine. There is a pair that I suspect should be used for heating. This pair was put in by the missing installer.

Any thoughts of fixing this?

Where are you located and why is the installer missing and where is he ?

Yet you are still unable to answer simple questions....
