M System


	a. Controller with thermostat c. Temperature sensor b. Signal distributor d. Valve with servo-motor
In the M System the devices have been equipped with a built-in voltage regulator, installed in the place for a traditional junction box. The very short cable connection (controller – Engine) guarantees the reliability of this solution. It is also worth mentioning that the 0 – 10V signal is sufficient to control the fan. Thanks to the AUTO function of the VNT20 or VNTLCD controller, it gives the possibility to automatically adjust the rotational speed of the fan according to the temperature difference: the temperature measured and set at the controlling unit. This solution allows the control of 10 devices maximum by use of 1 controlling unit only. There is a possibility to integrate the control to form the BMS system or any integration with other devices.
ADVANTAGES COMFORT • Air temperature in the room is kept at a desirable level (keeping comfort level temperature) • Automatic control of device operation • An option to program a weekly calendar • Very small system inertia - prompt reaction to temperature fluctuations SAVINGS ON OPERATING COSTS • Low heat energy consumption – the device delivers as much heat as required at a particular moment • Low consumption of electricity INVESTMENT SAVINGS • Lower installation costs in the case of control without valves • One controller for up to 10 devices SILENCE • The fan operation is at the lowest possible rotational speed to allow thermal comfort to be kept • Lack of fan operation cycles based on sudden on and off switching
SELECTION Choose an “M" version device of the LEO family Select the amount of devices that is appropriate for the heating of the building Additionally, choose the appropriate amount of mounting consoles for heater mounting at various angles (LEO FS has the console included) Choose CONTROLS Choose an appropriate 0-10V controller for each zone – one controller for a maximum of 10 devices VNT20 and VNTLCD controllers – can operate in CONTROL mode (the efficiency of the device depends on the room temperature and tasks) or in MANUAL mode (manual efficiency setting) The VNTLCD controller has an additional built-in programmable weekly calendar and an antifreeze function Choose an additional R10 regulator for each controller that operates more than 1 device This facilitates signal distribution and arranges wires Choose the temperature sensor (if air temperature will be measured in a place different than the controller) You can connect 1 or 4 PT1000 sensors to one controller PT1000 IN – temperature sensors of IP20 protection degree PT1000 OUT – temperature sensors of IP65 protection degree We would try to choose an appropriate amount of valves that control the heating medium flow In Auto mode there is no need to use servo-motor valves - the boiler controls the medium flow on its own SRV2d / SRS – cuts off the heating medium flow to the heater or to the whole zone SRV3d – cuts off the heating medium flow to the heater or to the whole zone simultaneously redirecting it to the return pipe

AUTOMATICS

VNT20	0-10 V Controller with a built-in interior thermostat A fan rotational speed controller cooperating with an “M” version device allows fan efficiency adjustment ranging from 0 up to 100%. An option of functioning in two modes: AUTO and MANUAL. “AUTO” mode allows automatic adjustment of the rotational speed of the fan depending on the temperature set and the temperature measured at the controller. In "MANUAL” mode the fan speed is adjusted manually with an option of CONTINUOUS work (the fan operates at a constant speed regardless of the thermostat) or THERMOSTATIC (the thermostat switches off the valve and fan). One controller controls the operation of 10 devices by use of an additional signal distributor R - 10. You can connect an external temperature sensor PT - 1000. Power supply: 230 VAC/50 Hz Temperature setting range: from +5 to +35°C Working temp. range: from -10 to +60°C Rotation setting range: 0 - 100% Degree of protection: IP50 Mounting method: surface mount		page top
VNTLCD	0-10 V Controller with a built-in interior thermostat and weekly programmer A fan rotational speed controller cooperating with an “M” version device allows fan efficiency adjustment ranging from 0 up to 100%. It has a built-in thermostat with a programmable weekly calendar. The Controller can function in two modes: AUTO and MANUAL. “AUTO” mode allows the automatic adjustment of the rotational speed of the fan depending on the temperature given and this measured at the control. In "MANUAL” mode the fan speed is adjusted manually with an option of CONTINUOUS work (the fan operates at a constant speed regardless of the thermostat) or THERMOSTATIC (the thermostat switches off the valve and fan). In addition, it has been equipped with an antifreeze function securing the interior against temperature fall below tp = 10°C. The fan of the device switches on automatically and the valve servo-motor opens, until the interior temperature reaches tp = 12°C. After reaching this value, the fan will switch off and the valve will be closed. One controller controls the operation of 10 devices by use of an additional R – 10 signal distributor. You can connect an external PT – 1000 temperature sensor. Power supply: 230 VAC/50 Hz Temperature setting range: from +5 to +35°C Temp. range: from -10 to +60°C Rotation setting range: 0 - 100% Degree of protection: IP20 Mounting method: Surface mount		page top
R10	Signal distributor Due to the use of a signal distributor it is possible to use one controller to control the operation of up to 10 devices from one source. Working temp. range: from -10 to +60°C Degree of protection: IP54 Mounting method: surface mount		page to
PT1000 in PT1000 out	External temperature sensor An external PT - 1000 temperature sensor is available in two versions: with protection degree of IP20 or IP65. Its application allows: • Temperature measurement elsewhere from where the thermostat is installed • Use of 4 sensors – providing average temperature readings of the whole interior • Device operation to be dependent on external conditions Max. distance from the controller - 50 m Working temp. range PT1000in: from -20°C to +70°C Working temp. range PT1000out: from -50°C to +110°C Protection degree: IP20 or IP65		page to
SRV2d	Two-way valve with servo-motor An ON/OFF valve with a thermo-electric servo-motor, mounted at the point of water return from the exchanger, allows the heating medium flow to be cut off. It is fitted for cooperation and compatible with the RA, RD interior thermostat. Power supply: 230V/50Hz Max working pressure: 1,6 Mpa/16 bar Max ambient temperature: 50°C Max medium temperature: 130°C Degree of protection: IP44 Max power consumption: 3 W Max continuous current of operation: 0,014 A Max momentary current: 0,6 A Thread: 3/4" Fully open – time: 150 s KVS: 3,5		page to
SRV3d	Three-way valve with servo-motor An ON/OFF valve with a thermo-electric servo-motor, mounted at the point of water return from the heat exchanger. Allows the heating medium flow that feeds the heater to be cut off and simultaneously redirects the hot water stream directly to the medium return pipe. It cooperates with the RA, RD interior thermostat.
