eading time switches and heating controls manufacturer, Sangamo, has added new Bluetoothcompatible timers to its DIN Rail


Time Switch collection. Designed to offer convenience and versatility to the user and broaden the product category reach to a wider potential market, the new range will help manage costs in residential, commercial and industrial applications. It uses Bluetooth technology to programme the timer and is compatible with Android and IOS, and applications include lighting, security, heating, ventilation, irrigation and horticulture. The current Sangamo DIN rail time switches use Near Field Communication (NFC) to programme the timer from an Android device.

The size of a switch and intuitively operable: KNX eTR 101 heating controller

temperature controller for KNX


NX eTR 101 is a heating controller for the KNX building bus system. The switchsized control unit is placed on site in the room. The


controller automatically ensures the desired room temperature and enables individual readjustment via touch surfaces. The simple user interface allows use in both private and commercial areas, especially in hotels, where the user wants to adjust the room temperature quickly and intuitively. "Plus" and "minus" for setting are understood internationally and are supplemented by a temperature value display. The real glass surface is both elegant and durable. The design language matches many current furnishing styles.


KNX eTR 101 measures the temperature on site


and controls the heating and, if necessary, the cooling via integrated PI controllers. Singlestage and twostage systems can be controlled. All settings such as connected systems and target temperatures for the operating modes Comfort, Standby, Eco and Building Protection (according to KNXHVAC standard) are made in the KNX application of the room temperature controller. Here it is also determined whether the measured value, target value or the basic setpoint shift is displayed on the device and the setting range is limited. This allows the KNX eTR 101 to be adapted to large as well as small projects.

installing two separate booster sets, one for the cold water and another for the operation of the sprinkler system, you only need a single unit – Saving space and money. Manufactured to meet the requirements of BS 9251. How it works: If a signal from the BMS or the sprinkler control system activates the sprinkler mode on the unit, all pumps will run continuously at full speed. The unit is

This allows for optimum charging of two devices at the same time, without fear of fluctuations in the power supply interfering with the charging process. Unlike some products on the market, the total power available is 4.2A, allowing both ports to deliver 2.1A at the same time, so you are guaranteed optimum charge every time, regardless of the devices being charged.

Carrier updates customers on implications of EcoDesign for chillers, heat pumps and AHUs


customers on the implications of the legislation for HVAC equipment. EcoDesign regulations apply


C


across the European Union, and introduce new minimum efficiency requirements for new chillers, heat pumps and Air Handling Units (AHUs) as a means of reducing energy use by buildings and industrial process cooling plant. The requirements are being


introduced in stages, with significant changes implemented on 1 January 2018 and important future changes planned for coming years. The changes include the use of new metrics for calculating seasonal energy efficiency, designed to better reflect real world operating conditions and give a more accurate measure of actual energy consumption. In the case of chillers for


comfort cooling, this calculation will be based on a new


standardised Seasonal Energy Efficiency Ratio (SEER) and primary energy efficiency. For chillers used in process cooling applications, Seasonal Energy Performance Ratio (SEPR) will now be used, to take account of the different operating conditions in these applications. Equipment will have to meet minimum efficiency standards in each area. For heat pumps (rated up to 400kW), equipment will have to meet a minimum acceptable Seasonal Coefficient of Performance Ratio (SCOP) for a range of different temperature bands, depending on the intended system operation.

awareness of the impact of buildings on occupant health has raised the profile of the building services sector. It has also highlighted the important role of the commissioning specialist in making sure that key equipment installations are set up correctly and, therefore, will continue to perform well throughout their operating life. However, deadlines on building projects can often be so tight that the commissioning of heating and hot water equipment is sometimes arranged just a few hours before the building needs to be handed over. This can make it difficult to address any problems, according to Lochinvar’s service manager Paul Mitchell. “We do what we can under the circumstances, but


advanced planning and earlier involvement of specialists would help deliver a better longterm outcome for the building user,” he said. “Commissioning of heating and hot water equipment should be considered as early as possible in the process so that easy access to the equipment is included in the design and comprehensive technical information is passed on to the commissioning team. “This not only helps with the handover process, but also means the pieces are in place for ongoing service and maintenance,” added Mr Mitchell.


ushed or poorly planned commissioning is undermining the heating and hot water industry’s efforts to reduce energy use and


Joined up Lochinvar believes a collaborative approach is more important than ever because of the growing trend of integrating renewable technologies, such as heat pumps with high efficiency boilers and water heaters. The initial set up of such systems is particularly crucial in ensuring that a system with different technologies works in harmony. “Manufacturers have intimate knowledge of


their products and applications, and their commissioning engineers will already have experienced most of the technical challenges they are likely to meet,” said Mr Mitchell. “This allows them to quickly identify potential issues and ensure the system is set up to perform well throughout its operating life.” The commissioning team at Lochinvar is able to


make sure boilers and water heaters operate at maximum efficiency from day one and can spot potential problems quickly because of their detailed knowledge. They will also issue a commissioning report, which is a valuable resource for facilities managers as it helps ensure warranty conditions are met. The company’s engineers are also able to assist


onsite staff with the operation of the equipment, including some targeted training. “As buildings become more complex and


performance challenges increase, the role of the commissioning engineer must be given greater attention and status,” said Mr Mitchell.

“The secret with increasingly sophisticated heating and hot water solutions is to ensure the sophistication remains behind the scenes and the equipment is relatively simple to operate for the


building occupiers; otherwise, the performance will drift over time.”
