Aquastat question

[McKraut]

Are we sure we didn't move any wires from their original position? RIB relay gets wired in parallel with the actuator.

You are correct. I pulled the thermostat wires. I am on my way downstairs to correct it. I'll let you know.

I wired it in parallel with thermostat wires. I have the yellow and orange on the Aquasmart, and wh/yel and wh/blu on the TEKMAR. The RIB's light was flashing quickly and it was clicking (in concert with the light flashing). The oil burner kicked on without a call for heat from the TEKMAR.

The RIB will stay constantly lit when powered correctly. What I'm trying to do is get the RIB to close T-T on the Aquasmart when the 3 way valve is set for flow to the Buderus. We can do it a few different ways. We need to know what terminals have power on the 3 way valve and when (what position). The RIB has normally open and normally closed contacts allowing us to do it a number of different ways.

Ok. I jut spent the last hour or so measuring voltage across the actuator in response to the display on the TEKMAR. I'm not sure if it is new, or it is just the first time I noticed it, but when I power up the oil burner, and there is no call for heat, the actuator closes the 3way. When there is call for heat from Stage 1, there is no change in position of the actuator. When stage 2 calls for heat the actuator opens the 3way valve. Is it possible I was told to put the 3way valve in backwards? I have "B" as N/O and "A" as N/C (yes that looked backwards to me before I put it in, but I did ask and verify that is the correct way to install it). If that's not the problem, I can give you all the results for the voltage tests I did this morning.

Do we currently have any wires between the actuator and the Aquasmart?

 

[McKraut]

Yes, there is still the thermostat wire. (I disconnected the RIB because it continued to chatter and fired the oil burner)

Without the RIB attached:

With power to the oil boiler off, valve is open, and there is no voltage at actuator

With power to the oil boiler on, and no call for heat, valve closes and there is 24 volts between blue/brown and blue/black

With power to the oil boiler on, and first stage calls for heat, valve stays closed, and there is 24 volts between blue/black and small amount of voltage (around 1/4V) between blue/brown

With power to the oil boiler on, and second stage calls for heat, valve stays closed, and there is 24 volts between blue/brown and blue/black

If I turn off power to the oil burner, the valve opens.

This is what I recorded this morning. Now that I am reading it, something must be wrong. I would think that the RIB would be lit and not chatter with the boiler on because it is getting 24 volts from the acuator. I won't be able to check it tonight or tomorrow because of Christmas. I will check it out this weekend and recheck the data and record it for you.
Thank you for all your help so far. Have a wonderful Christmas.

Where are you on L.I.? My son lives in Port Jeff.

We'll get this sorted out Bob, I'll digest your last post and we'll come up with a plan.
Pt. Jeff isn't far, less than ten miles, I'm in Ridge.

Enjoy your Christmas as well.

Hi Ron,

Can you open a Excel file? I can't post it here. I took a bunch of readings today and I would like to send them to you.

Thanks,

Bob

I think I have Office on one of my pc's, I'll sure try.

Ron,

Scratch that. It wouldn't let me drop the file in the message. Can you send me an email address?

Update, it appears we've found a fix that Mr. McKraut can live with.
Just wanted to let everyone know what a great resource this forum is for all of us.
Glad I could help.

Ron


Ron,

I wanted to send you an email to let you know everything is working
just fine. I put in a switch to reset the zone valve to open whenever I
go back to wood. I just flip the switch and I am ready to go. Several
times over the last 2 weeks the wood boiler could not keep up with the
cold temperatures (it's been as low as -9°), and the oil kicked on some
time in the middle of the night. We woke up to a warm house, thanks to you.
Keep warm and thanks again,

Bob

What was the fix?

 

[McKraut]

What was the fix?

Ron will have to explain it to you or maybe you will be able to deduce it from the information below. I followed instructions that Ron gave me, but I have no idea why I did what I did.

Actuator Wires -- Connection(s)

Brown -- Stage 1 (RED) on TEKMAR

Blue -- Stage 2 (Black) -- Yellow/White from RIB

Black -- Stage 2 (Red) -- Blue/White from RIB

Thanks again to you, Ron, and Scott (Clarkburg).

I can't tell you how happy I am now that my wife is warm.

Glad you got it sorted Bob! Happy wife, happy life!
