Description for Tekmar 260


The Tekmar 260 boiler control is a microprocessor-based control designed to regulate the supply water temperature from a single boiler based on either outdoor air temperature or a DHW demand. The 260 can control either a DHW pump or valve and provide DHW Priority. A tekmar indoor sensor can be connected to the Tekmar 260 in order to provide indoor temperature feedback from the heating system.

                          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.

                                      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.

                                          A non-condensing boiler generally should not be operated below 140 degrees F. When configuring the Tekmar 260, the type of terminal unit will influence the recommended design supply temperature (BOIL DSGN), and minimum supply temperature (BOIL MIN) for greatest efficiency. For your non-condensing boiler, do not specify a temperature less than 140 degrees for BOIL DSGN or BOIL MIN. Take a look at Terminal Units on page 6, and section B3 on page 7 of the Tekmar 260 Data Brochure for more detailed explanation.

                                          I believe it is. I have a Weil MClain. I live in New York,. The lowest temp my boiler ran at was 135 degrees. I didn't notice any condensation issues. Over the past 2 years. I have hot water baseboard, I only noticed a problem with a room over the garage. Since water running through baseboard was not 190 degrees that room had trouble maintaining temp on cold days. I added about 3 feet of baseboard and had no more issues. It has been difficult estimating savings, because the winters have been very different since I put it in. Unfortunately my electric utility was working on the lines and caused a power surge that wiped out the tekmar. I'm waiting to see if they are going to pay to replace it. I hope this was helpful

                                          The 260 should will work fine for you if you set the lowest set point to
                                          140. This will virtually eliminate the risk of condensation as the return
                                          temperature should be greater than 120 deg.

                                          The boiler temperature is a settable item in the controller. My memory is
                                          that the Tekmar 260 has a minimum low setpoint of 140 degrees. It will not
                                          allow you to program a boiler setpoint below that temp. Nor does the
                                          outdoor reset schedule allow for a lower temperature than that. That
                                          setpoint is the temperature of the fluid in the boiler, not your stack
                                          temperature. Low stack temps mean shorter run times to achieve the
                                          setpoint, not lower combustion temps in the burner chamber. If you are
                                          worried about condensation due to short run times, then pick a higher value
                                          for your minimum boiler temp.

                                          yes it is and as far as the condensation is concerned during the setup the 260 will need input on the unit its being hooked up to and one of the settings is for you to check the manufactures suggested lowest allowable temp to prevent condensation so what ever temp you input the 260 will never fall below that temp it also will need the highest allowable temp as well and it will never let the boiler get any higher than that number . The 260 is a perfect fit for your application just remember you need to install a sensor well in the boiler so it can read the water temp .This is not included in the kit

                                          Sounds like a good match. I have the same basic boiler. I've used this
                                          controller for two seasons and haven't seen any condensation. This unit has
                                          delayed firing to prevent short burns and you can set the low(and high) temp
                                          limit by preset or change it manually to your own needs.

                                          The 260 has a lower temp limit setting to try to limit condensation problems, but I've never used it, so I can't verify how well it works. Without adjusting this setting, I suspect you'd for sure run into condensation problems with the outdoor reset feature & sensor enabled.

                                          No, the replacement for the Tekmar 353 would be the Tekmar 356.

                                          The temperature sensor can not be adjusted, as it simply reads the outside temperature. If the readings are not accurate, it could be that the sensor is defective, the wiring of the unit is incorrect, or the sensor is not placed in the right location. It should be situated on the north side of the house without exposure to direct sunlight, otherwise the readings could be incorrect.

                                          As long as you have a one stage boiler, this model would be the correct unit.
