Landis & Gyr PolyGyr controllers

[lenb]

Ran into a couple old Landis & Gyr digital temp controllers on a job today, and was wondering if anyone might have or know where I can find any info on these. Can't find anything on Siemens web site.

Found a pic of one on e-bay, it is a RWF 61.10. There is also a RZF 61.10 solar compensation controller. They might be about 17 years old, controlling some baseboard radiation loops.

I remember those (and the brownish plastic room sensors).
I'll check and see if I have any documentation at work tomorrow.

Here are some of the original data sheets.

That is awesome, didn't think I would find any info on these. Thanks.

Checked the mixing valves that they are controlling today (pneumatic, thru transducers), and found they were physically stuck in one position.
Packings have probably been leaking for years, packing gland and valve stem corroded bad. Freed them up and jammed them open for now, will replace them.

The controllers appear to be working. The digital display modules on them, though, not sure how they work. One of the displays on one of the RZF shift controllers is blinking on and off. They display the sensor value, and X1, or X2 as you push the button. Didn't look at them very long, but I should be able to figure out what it all means now.

You wouldn't happen to have the data sheet # 3424 they mention, would you?

I'll check.

Here is what I found for the display module.

Thanks, that helps a lot.
Now I know what those different indications mean.

I'm Working On The Same Control, What About Any Data On The Temperature Sensor Connected To It Like Resistance Ranges?

Lost0ne, i don't suppose you would have a datasheet for a rwf21.20, we can find a german version but not very helpful

Not sure if these files are any help, but here they are anyway!

Wow, I didn't think anyone had this documentation any more. I am looking for the datasheet for a RWF 61.30_ controller. Very similar to the 61.10, but a couple more functions. If anyone has a copy, could they please post as an attachment?
Thanks in advance!

Does anyone have pdf manuals for PolyGyr RWF61.2 & RWF61.14?
Thanks

I'm looking for the following data sheets/manuals - finally found this website mentioning some. they are principally;
POLYGYR RWF 61.10, RZM 61.40 & SEZ 61.5.
Any info much appreciated. How do I download the datasheets as there are no attachments.
