Perfect Replacement Part

My home uses the Tekmar 356 as a mixing control for the hydronic floor heating system. It was present when I moved into my home which was built about 11 years ago. A few weeks ago, as the weather started to become cold again, I noticed that the unit had burned out. I ordered a replacement from PexSupply.com, and installed it in about 20 minutes. Now my floor heat is working perfectly again.

I have used this product many times.

The Tekmar 356 Injection Mixing control with outdoor reset is the minimum mixing device I will install on a multi temperature radiant/ hydronic system. The 356 is a more economical mixing control device then most products on the market that offer the same functionality. NASA grade controls for your hydronic and HVAC systems Literally!

Mix it right

356 control is the best control for basic pump injection. We use is all the time when running a two temp system. Does not work well with the new ECM pumps so make sure to throw it on a Taco 007 or comparable.

Full of features

I'm using this in my house to control the temp to my zone circulators. It works as advertised. Easy set up if you have done heat load calcs. Able to input all design parameters and the reset curve works perfectly. Menus are easy to navigate. If it has "a mind of it's own" it probably wasn't wired correctly. Lost a star due to price

This control has the option of using a boiler sensor. If the boiler sensor is on the boiler return and the boiler return temperature measured by the sensor is at or below the boiler min setting then the injection is ramped down to allow the boiler loop to heat back up, thus providing boiler return protection to the boiler.

Yes, the 356 is the direct cross reference of the 353.

If you are doing variable speed mixing with a circulator, you need the 356 control. If you are using a modulating mixing valve, you need the 360 control.
