A great way to extend the capability of Tekmar controllers
Very high quality product
Nice design - external activator a help
Just Like The Original
Excellent. Worked exactly as advertised
Product Q&A
3 QuestionsQ: Would this unit serve as a switch for a circulator on a simple "call for heat" from a tstat? Much like a Taco 501 functions? The 501 has a bunch of features we never use when setting up a multi-zone end switch zone valve system.

Verified Reply- Supplyhouse Staffit should, as long as you dont need more than 2 accessories to engage.
Q: I'm looking for a relay that I can mount on a board, next to a control module. Is this relay configured to fit into some sort of an electrical box, to protect the 120 volt wiring? If it's not, what model of simple relay do you recommend for this application? Thanks.

There are several approaches that can be used to address your requirement. The Tekmar 003 relay can be mounted with screws or it mounts on a DIN rail, so it can be used in any enclosure that meets your needs. You might consider a large enclosure to house both the Tekmar control and the relay(s), or alternatively you can use a smaller enclosure just for the relay(s). If you are using several Tekmar 003 relays then any enclosure that meets the 120V electrical codes should work well. In the case of a single Tekmar 003 relay, an octagonal electrical box with an extension ring works well as an enclosure. The extension ring is typically available at any electrical supply house, for example http://reviews.homedepot.com/1999/100544210/1-gang-15-5-cu-in-octagon-extension-ring-reviews/reviews.htm. In addition an octagonal box and cover are required. This is an easy and inexpensive solution that should meet most local code requirements.
I mounted mine in a basic metal box. You would not need to mount it in a box per say but depends on your electric code.
Q: does this fit the Tekmar 252

The Tekmar 352 appears to be a single zone control for a hydronic heating system. If that is a correct description for the 352 in question, then this relay is compatible with that device. The unit runs on 24 volts a.c., which is the proper voltage to operate this relay. I hope this helps. Hal Ferguson
The Tekmar 24V relay can be used for a wide range of applications. It will integrate very well with the Tekmar Two Stage Boiler & DHW Control 252. Keep in mind that the Tekmar 24V relay must be installed to meet local wiring codes that generally require the use of an enclosure for switching high voltage loads. For example, the 24V coil relay can be used to switch a 120V circulator, and in that case should be housed in an enclosure. The enclosure is not included and must be procured separately. You might want to enclose the Tekmar 252 and any required relay(s) in one enclosure, or you can use the Tekmar 252 with it's native enclosure and provide an additional enclosure just for the relay(s). If you provide additional information about your particular requirements or proposed design I might be able to provide additional insight into the use of the Tekmar 24V relay.
It depends entirely on what you want your Tekmar 252 to do, and how you wire it up. It is not a simple plug-and-play installation.
cutter123, I used the Tekmar Relay on the 256 Control and it works just fine, I checked out the Tekmar 252 and it will work just fine there too. Great systems, I have mine working with a 4 zone oil-fired base-bd hot water, in a 1901 house
