Page 4: Introduction
Its use will ease a more efficient consumption of energy resources, resulting in savings for the user. KEM is able to measure and report in the KNX system the values of energy, water consumption and caloric energy along with other magnitudes related to these three. -
Page 5: Installation
KEM (7). The flow meter will be supplied from the 5V power output of KEM (5). Note that this output will only be live if at least one of the channels for water measurement is enabled in the parameterisation (see section 2.3). - Page 6 (return) of the air-conditioning circuit. For this purpose, the temperature probes incorporated in the flow meters and fittings supplied by Zennio can be used. Each one of these probes can be connected in any of the 5 analogue/digital inputs (1).

Page 7: Measured Quantities
1.3 MEASURED QUANTITIES Next, the quantities measured by the KEM that can be sent to the bus for monitoring are described. 1.3.1 ELECTRICITY Magnitudes of each conductor or phase: Current: rms value expressed in milliamps [mA]. Active power: effective power capable of transforming electrical energy into work. -
Page 8: Water
It is measured in joules [J]. Heat/cool quantity: sum of the calorific energy consumed during both heating and cooling. It is enabled by an ETS parameter and is always measured in joules [J]. http://www.zennio.com Technical Support: http://support.zennio.com... -
Page 9: Data Inicialization After A Download
It is important to note that global objects are always the sum of channels or phases, so it is not possible to set a value after download for these nor have flag W enabled. http://www.zennio.com Technical Support: http://support.zennio.com... -
Page 10: Setting The Time Of Day
For certain functionalities, such as periodic registers or the starting date of each register, it is necessary to set the time of day of KEM through a master clock in the installation. During the start-up, KEM will request the time of day to the KNX bus through the objects “Date”... -

/ disabled]: if this parameter is enabled, will be sent a periodic request for date and time every 15 minutes. The default values of each parameter will be highlighted in blue in this document, as follows: [default/rest of options]. http://www.zennio.com Technical Support: http://support.zennio.com... -
Page 12: Partial Registers: Global Configuration
In this tab you can configure the periodic reset of partial registers. In order for this tab to be displayed, it is necessary to have at least one partial record enabled for one of the magnitudes (electricity, water or heat quantity). See sections 2.2.1, 2.3.1 and 2.4.1. http://www.zennio.com Technical Support: http://support.zennio.com... - Page 13 In case of selecting “Same Day of Month”, the specific day of the month will change whenever the register is manually reset through the object “Reset Partial Registers n”. http://www.zennio.com Technical Support: http://support.zennio.com...

Page 33: Notifications
2.5 NOTIFICATIONS Notifications in KEM consist in sending a binary object to the KNX bus when the selected variables, stored in either total or partial registers, reach a pre-set value. The variables on which it is possible to configure notifications are water consumption and electricity consumption for global and individual magnitudes. - Page 34 Action [Send 0 / Send 1]: set the value to be sent through the binary object “Notification n: __________” when the notification is triggered. http://www.zennio.com Technical Support: http://support.zennio.com...

Page 35: Alarms
2.6 ALARMS In addition to notifications, KEM implements 7 alarms to monitor electric power, electric current and water flow, which can be enabled and parameterised independently. It will be possible to set an upper and a lower limit for any of the variables. When these limits are exceeded, the device will send a binary value through the different objects. - Page 36 This limit can also be set via the object “Alarm n: Set Upper Limit”. ➢ Action [Send 0 / 1]: set the value to be sent through the object “Alarm Send n: Excess _____” when the alarm is triggered. http://www.zennio.com Technical Support: http://support.zennio.com...
- Page 37 ➢ Hysteresis Above the Limit: defines a dead band for alarm deactivation. When active, the alarm will not be deactivated until a value over the limit plus hysteresis is reached. The units will coincide with those configured for the chosen channel/phase. http://www.zennio.com Technical Support: http://support.zennio.com...
