MULTICAL® 801 DATA SHEET Precise measuring of heat and cooling up to 30,000 m³/h Remote reading with four communication channels 4 analogue outputs Two plug-in modules simultanously: GSM, M-Bus, RadioRouter, LonWorks pulse inputs for electricity and water meters Data logger with latest 460 days, 36 months and 15 years as well as programmable data logger Complies with EN 1434:2007 Class C and MID M1, E1 and E2 MID-2004/22/EC M12 0200 DK-0200-MI004-009 IP67 Application MULTICAL ® 801 is a robust and rugged calculator. It is ideal for buildings and industries using extra communication possibilities, programmable functions and a wide range of other modules. MULTICAL® 801 is used for measurement of both heat and cooling in all water based plants with flow temperatures from 2°C to 180°C and with all flow meter sizes between qp 0.6 m³/h and qp 30,000 m³/h. The meter is simple to install, read and verify. Furthermore, MULTICAL® 801 contributes to keeping the annual operating costs at a minimum with its unique combination of high measuring accuracy and long lifetime. If MULTICAL® 801 is connected to flow meters installed in both flow and return pipes, the meter can monitor leaks and burst in the heating/cooling system. Furthermore, leakages in the tap water system can be monitored by means of pulses if a water meter is connected. MULTICAL® 801 can be extended by two independent modules in the form of GSM/GPRS, M-Bus, RadioRouter and LonWorks. The modules also include two extra pulse inputs for connection of water and electricity meters. The modules make remote reading of the meter possible. MULTICAL® 801 receives volume pulses from the connected flow meters and calculates the energy for every predetermined water volume. The energy calculation includes temperature measurements in flow and return as well as correction for density and heat content according to EN 1434. MULTICAL® 801 fulfils the IP67 requirements to very rugged design and robust functionality. The IP67 seal guarantees that the meter is resistant to dust, humidity and water. Pulse outputs, valve control, battery backup and many other features are standard functions in MULTICAL® 801. MULTICAL® 801 can be supplied by 230 VAC or 24 VAC.

The energy calculation can in a simplified way be expressed as: Energy = V x ∆Θ x k. V is the supplied water volume ∆Θ is the temperature difference measured k is the thermal coefficient of water The calculator always calculates energy in [Wh], and then it is converted into the selected measuring unit. E [Wh] = V x ∆Θ x k x 1000 E [kWh] = E [Wh] / 1,000 E [MWh] = E [Wh] / 1,000,000 E [GJ] = E [Wh] / 277,780 E [Gcal] = E [Wh] / 1,163,100 Application types MULTICAL® 801 operates with 9 different energy formulas, E1...E9, that are all calculated in parallel in connection with each integration no matter how the meter is configured. The energy types E1 to E9 are calculated as follows: E1=V1(T1-T2)k Heat energy (V1 in flow or return) E2=V2(T1-T2)k Heat energy (V2 in return) E3=V1(T2-T1)k Cooling energy (V1 in flow or return) E4=V1(T1-T3)k Forward energy E5=V2(T2-T3)k Return energy or tapping from return E6=V2(T3-T4)k Tap water energy, separate E7=V2(T1-T3)k Tap water energy, flow pipe E8=m³xT1 (Flow pipe) E9=m³xT2 (Return pipe) This renders MULTICAL® 801 capable of calculating the heat and cooling energy of most applications, both closed and open systems. All energy types are data logged and can be displayed independent of configuration. 5810625_H1_GB_02.2012 3 MULTICAL® 801 DATA SHEET Calculator functions Example 1: Closed thermal system with 1 or 2 flow sensors Example 2: Closed thermal system with 2 flow sensors Example 3: 2 heat circuits with joint flow Example 4: Open system with 2 flow sensors Flow measurement MULTICAL® 801 calculates current water flow according to two different principles depending on the connected flow sensor type: • The flow indication of electronic flow meters is updated every 10 seconds. • The flow indication of mechanical flow meters, typically with reed contact, is calculated on the basis of periodic time measurement and is updated with each volume pulse. 4 5810625_H1_GB_02.2012 MULTICAL® 801 DATA SHEET Calculator functions Power measurement MULTICAL® 801 calculates current power on the basis of current water flow and the temperature difference measured in connection with the latest integration. Current power is updated in the display simultaneously with the flow update. Min. and max. flow and power MULTICAL® 801 registers minimum and maximum flow and power on a monthly as well as on a yearly basis. The registrations which appear from the display or can be read via data communication include max. and min. flow and power values, all with date indication. All max. and min. values are calculated as largest and smallest average respectively of a number of current flow or power measurements. The average period used for all calculations is selected in the interval 1…1440 min. Temperature measurement MULTICAL® 801 is available in different versions for either Pt100 or Pt500 sensors as well as in 2-wire and 4-wire versions. The measuring circuit includes a high resolution analog/digital converter with a temperature range of 0.00…185.00°C. In addition to current temperatures for the energy calculation average temperatures on a yearly and monthly basis can also be displayed. 5810625_H1_GB_02.2012 5 MULTICAL® 801 DATA SHEET Calculator functions Display functions MULTICAL® 801 is equipped with a clear LC display including 8 digits, units of measurement and information panel. In connection with energy and volume readings 7 or 8 digits and the units of measurement to match are used, whereas 8 digits are used when e.g. meter number is read. As a starting point the display shows accumulated energy. When the push buttons are activated the display reacts immediately by calling other readings. The display automatically returns to accumulated energy reading 4 minutes after the latest activation of the push buttons. ® MULTICAL 801 The upper push button is used to switch between the primary readings. The consumers typically use the first primary readings in connection with self-reading for billing purposes. The lower push button is used to show secondary information on the selected primary reading. Info codes MULTICAL® 801 constantly monitors a number of important functions, e.g. power supply, temperature sensors and leakage alarms. Should a serious error occur in the measuring system or in the installation, a flashing “info” will appear in the display whilst the error exists. The “info” panel will automatically disappear when the error has been corrected. An info event logger indicates how many times the info code has been changed. The info logger stores the latest 50 changes, of which 36 can be displayed. 6 5810625_H1_GB_02.2012 MULTICAL® 801 DATA SHEET Calculator functions Standard Info code Description Response time 0 No irregularities - 1 The supply voltage has been interrupted - 8 Temperature sensor T1 outside measuring range 1…10 min. 4 Temperature sensor T2 outside measuring range 1…10 min. 32 Temperature sensor T3 outside measuring range 1…10 min. 64 Leak in cold water system 24 hours 256 Leak in heating system 24 hours 512 Burst in heating system 120 sek.

The meter contains the following data loggers which can be read on the display or via serial data: 5810625_H1_GB_02.2012 Data logging interval Data logging depth Logged value Yearly logger 15 years Counter register Monthly logger 36 months Counter register Daily logger 460 days Consumption (increase)/day Programmable data logger 1080 loggings (e.g. 45 days‘ hour loggings or 11 days‘ 15 min. loggings) 30 registers and values Info logger 50 events Info code and date 7 MULTICAL® 801 DATA SHEET Calculator functions Leak surveillance 16 14 Leakage inkg/time kg/hour Lækage Lækage ii kg/time 12 10 8 6 4 2 0 400 410 420 -2 430 440 450 460 Antal dage Antal dage Number of days District heating systems The leak surveillance system is primarily intended for direct connected district heating installations. The surveillance system consists of two water meters based on the ultrasonic principle, placed in flow and return pipe respectively, and of temperature sensors in both pipes. MULTICAL® 801 monitors the mass difference that may appear between flow and return pipe. Cold-water systems The pulse signal from the cold-water meter of the house can be connected to MULTICAL® 801. In this way it can monitor the cold-water consumption. A flushing toilet cistern, leaky heating coils in the water tanks or other leaks will cause that impulses from the cold-water meter are received 24 hours a day. Pulse outputs CE and CV MULTICAL® 801 has pulse outputs for energy and volume pulses respectively. CE on terminals 16-17 releases one pulse per least significant digit of the energy count in the display and CV on terminals 18-19 releases one pulse per least significant digit of the volume count in the display. If a higher resolution of pulse outputs is required, a CCC code with high resolution must be selected. Pulse inputs VA and VB MULTICAL® 801 has two pulse inputs, VA and VB, to collect and accumulate pulses remotely, e.g from cold-water meters and electricity meters. The pulse inputs are physically placed on ”Module 1”. The pulse inputs VA and VB function independently of the other inputs/outputs. 8 5810625_H1_GB_02.2012 MULTICAL® 801 DATA SHEET Calculator functions Data connection [62-64] MULTICAL® 801 has data connection on terminals 62-63-64.
