The intent of the two analog outputs (available on all -A model gas monitors) are to control the speed of a variable speed fan (VFD) or to send the gas readings to the analog inputs on a controller. By default both analog outputs are linear and have an output signal of 2…10 V or 4…20 mA (selectable via a jumper on the gas monitor PCB) proportional to sensor A and sensor B gas readings. They are also configurable via the programmable menu. For more information please refer to the gas monitor operating manual, available on the Belimo website: www.belimo.com/mam/americas/technical_documents/Support%20material/belimo_gas-monitor_operations-manual_en-us.pdf
Thank you for inquiring! For the US market currently only vehicle emissions (Carbon Monoxide and Nitrogen Dioxide) and IAQ (Carbon Dioxide and Relative Humidity) are available. But there are plans to expand the product range in the future. In addition to the vehicle emissions and IAQ monitors, combustible and toxic gas monitors are available to the Canada market. If you have any further questions, please let us know!
Thank you for inquiring! The study done by AIT is not available to the public. For more information regarding the study you can reach out to your local sales representative.
Can this valve also be used as bypass for minimum pump flow when the load is low? It means lower delta T for the coil than designed at this scenario. Thanks.
Delta T scaling can be used to enable lower delta Ts at low flows, rather than maintaining a fixed DT value. Alternatively, the Energy Valve can be configured in flow control mode with DT manager disabled to maintain a minimum flow. For further questions, please contact Technical Support at technicalsupport@us.belimo.com
One thing I am a little worried about is that if your coil's valve has been closed for a long time, the inlet temperature is probably going to be about the same as the return, which could mean having a false 0°C ∆T. Wouldn't it be better to use the supply temperature from the heating plant instead? Especially since it has a bacnet interface
We want to address the Delta T at the coil so inlet temperature closest to the coil is best. Delta T management is performed on an operational basis requiring a minimum flow rate to be activated. If a valve was closed, it would typically mean no heat exchange is occurring and no minimum flow rate is provided.
I have watched two of Belimo's webinars on this product and I am surprised to see their thoughts on the Calibration process for these devices. Basically "buy a new sensor - its good for a year' and oh ya if you want to do it MANUALLY then we will sell you some calibration gas. The Idea of looking up a calibration procedure is not to be told to replace the sensor because if the sensor is replaced it would be with a QEL unit that can be used for years with proper calibration. What ever happened to the time when companies stood behind their product and wanted to keep it working as long as they could. The information that I have read in the manual and been given over the phone is miss leading to the point of being wrong. From what I can see while trying to calibrate these devices you need to adjust a 'gain' value that will intern adjust the displayed level the sensor is reading. The question is 'what is the proper procedure to do this?' and do the sensors have a code to say they are at end of life?
Thank you for your feedback. We apologize for the delayed response. We worked closely with a product specialist to understand your concerns and provide feedback you will hopefully find helpful. Belimo gas monitors are factory calibrated, so when a customer purchases and installs them, they do not need to be calibrated during installation. However, additional factors must be taken into account, such as how long the gas monitors have been in storage and at what elevation they will be installed, so calibration upon installation is a good option but is often not required. After installation, Belimo gas monitors are required to be recalibrated annually, or more frequently as specified. Recalibration is done by flooding the sensor modules with gas and adjusting the zero and span values. This process of recalibrating ensures that the device is reading correctly and will react appropriately should gas levels rise above normal levels. For a detailed description of the calibration procedure on all Belimo gas monitors, please see the Belimo Operating Manual sections 6.2 to 6.5. After a gas monitor is recalibrated, it should read correctly and react appropriately until the next recalibration service is due. At some point, the sensor modules (the physical sensors inside the gas monitor that detect gas) will reach their end of life, which is when they should be replaced and can no longer be recalibrated. When a sensor module reaches its end of life, a code will be displayed on the LCD display. This is a safety precaution to force them to be replaced and not forgotten. Each sensor module has a unique end of life depending on the gas it senses. To see the end of life for all sensor modules, please see section 6.7 in the Belimo Operating Manual. To replace a sensing module, simply open the gas monitor's door, remove the sensor modules, replace them with new ones, and register the new modules. When the gas monitor's end of life is reached, only the sensor modules need to be replaced. Also important to note, all Belimo gas monitors are compatible with one another, mixing older and newer devices will not affect the functionality of the devices or of the system. For a detailed description on replacing and registering sensor modules, please see section 6.6 in the Belimo Operating Manual. A customer has the option of either recalibrating the gas monitor or simply replacing the sensor modules with new ones, depending on which option is more cost effective. It could be that the volume and location of the gas monitors do not justify the cost of having a trained technician come and recalibrate them. In such a situation, replacing the sensor modules (which can still be used for years) is possible. We are trying to continue to make Belimo gas monitors reliable, accurate, user friendly, and long lasting. If you have any more questions, concerns, or feedback for us, we would love to talk to you more about it!
I have Belimo nrf24a-sz Used on the cooling line. Always variable when temperature rises, sometimes 100% and sometimes 0%. Note that he must be a conqueror
It will depend on your application, heating or cooling.

Can you please help to solve this issue.. we have a old modulating actuator which is obsolete now. So now i’m replacing the new actuator. When i press the self adoption for 3s it goes to the direction and meeting the 1/2 inch valve scale from 0 to 100%. But during auto operation it doesn’t goes after 50%… When i check on the actuator terminals I receive the max control signal 10V , so now it supposed to reached 100%. then i measure the voltage on the actuator terminal i received 7.2v only, then i disconnected the actuator and measured it receiving 10V…Model is SVK24-MFT-50. I don’t know why . When my control signal gives 10v it supposed to go 100%.. but it’s not going after 50%.. my range is 2 to 10vdc. 0-100%, total 3 wires) -, + and control signal +) My PLC sends 10vdc but it doesn’t goes after 50%, But when manually change the direction it goes 0-100% properly

There are no replaceable fuses on the Belimo Devices, but we’ve got you covered. Belimo products come standard with a 5-year warranty, and the first 2 years of that warranty are unconditional. This means that if you or the contractor in any way damages that product during the installation; we will replace it like for like under the warranty.

Hi Yokelee - We are unsure what you mean with your question. If you provide us with your country location we can direct you to the correct technical support team who can help answer your questions.
Hello Juan, We estimate that you would save money using the rebuild kits as the installation of tearing down an old valve and replacing it with a new one is still going to be more than the replacement work which as you can see from Joe's tutorial is simpler. Additionally, there is a cost savings to a rebuilt kit than a new valve. If you have any additional questions about rebuild kits we would be happy to answer them!

Hi Raymond - Thank you for your feedback. You can find technical documentation for our ZoneTight Zone Valves on our Learn More page: www.belimo.com/us/en_US/products/valves/product-documentation/zone-valves Additionally, the technical documentation for the product range includes how to identify the flow rate (page 7). The flow rate is identified by a letter in the product number (For example: B = 0.9 GPM) www.belimo.com/mam/americas/technical_documents/Tech%20docs/belimo_zonetight_technical-documentation_en-us.pdf We hope this helps!
