Boiler Control - One Stage Boiler & DHW

Excellent control capable of automation of the heat curve. Easily installed for those who understand controls. Love the adaptive DHW priority. All of tekmar controls are great 👍

I used this on my boiler to automatically set the temperature of the boiler based on outside temp. Prior I had to manually increase boiler temp on super cold days or it would not hear all zones properly.

Use These Items In Apartment Complexes For Some Control Of The Heat But Unfortunately Most Buildings Are Not Piped To Operate At Lower Temperatures For Fear Of Condensing Cast Iron Boilers So The Usable Temperature Range Is Generally 160°F To 200°F Supply Temperature If System Is Sized With A 20° Delta T. If a System Is Piped As An Injection System, Primary/Secondary Or Makes Use Of 3 Way Or 4 Way Mixing Valves As Opposed To Straight Through You Will Get A Much Greater Range Of Temperature To Work With Which Will Result In Better Comfort And Fuel Savings. 14 Gauge Wire And Larger Is Difficult To Install In The Terminals.

Every hot water boiler with a indirect HW heater should have this control so you can save mucho$$$$$$$

Reset control and DHW priority

a great product to save on fuel costs

I have a five zone (two radiant floor, 3 cast iron radiator) system on newer non-condensing Utica gas boiler and had a problem with the house overheating. After t-stat stopped calling for heat and zones and boiler shut off the house would still build about to about 10 degrees over t-stat setting (this was at 160 degree water temp). Lowering boiler temp to solved problem but on cold days house was too cold! Tekmar 260 solved the problem! My only wish was that it had an relay for 120volt power connected to the warm weather shutdown feature that could be used to power my zone circulators. Tekmar's only solution for zoning is the more expensive TN4 system with multiple add on cards. I added my own WWSD for the zone circulators with a RANCO temp relay. Overall, the 260 is great and very smart. Not sure about savings because I had also added a zone in the basement but gas bills seem to be about same or little less that previous years. System is a true primary-secondary, three zone circulators (one with three zone valves for radiator zones) with boiler by-pass loop. I do not use the indirect domestic water heater feature but piped it for future use.

I had this unit installed in my 8 unit apt bldg, to use on HW Boiler...after 1 year, my bal. billing went from $420, to $275/month. A great savings due to less usage. Installing them on all my buildings.

The Tekmar 260 was easy to install and the directions to do so were very good. It is a good looking control and easily mountable. I still have to see how it works with my existing boiler controls during the winter months.
