2 Areas of application Useable volumetric flow ranges Volumetric flow controller for supply and return air systems, suitable for regulating a constant volumetric flow with the option of electrical setpoint adjustment (VM-PRO- -E) ATTENTION The VM-PRO is an adjusted controller working by the mechanism of action principle. Tampering with the controller, whether manually or mechanically, are prohibited. When a high volumetric flow setting has been selected, the damper leaf must never be closed manually. Otherwise, the control mechanism will be changed, resulting in a loss of control accuracy. The field of application must always be complied with. If the VM-PRO is used beyond its allowed field of application, this will result in mechanical overload and thus in a loss of control accuracy. We would like to point out that to clean the stainless steel design, only suitable corresponding cleaning materials must be used. CORRECTION FACTORS REGARDING THE AIR VOLUMES In controller positions 1 and 2, p must be >100 Pa. For p Pa deviations of up to 20% of the set value can occur. Maimum deviation compared to the set value: Air velocity 2-4 m/s ± 10% Air velocity 5-6 m/s ± 8% Air velocity 7-8 m/s ± 6% Air velocity 9-10 m/s ± 5% Scale accuracy ± 4% Maimum deviation compared to the set value:: NW 80 from a static minimum pressure difference of Δp 100 Pa Air velocity 3-4 m/s ± 20% Air velocity 5-6 m/s ± 16% Air velocity 7-8 m/s ± 10% Air velocity 9-10 m/s ± 8% Scale accuracy ± 4% Volumetric flow ranges for VM-PRO-R NW (mm) V ZU (m³/h) V ZU [l/s] min. ma. min. ma Volumetric flow ranges for VM-PRO-Q B H (mm) V ZU (m³/h) V ZU [l/s] min. ma. min. ma For the parameter setting of the control components, an air density of 1.2 kg/m 3 has been taken into account. When the air volume drops below the Vmin shown in the chart, the correct functioning of the volumetric flow controller is no longer guaranteed.

3 Function Processing Function Processing The constant volumetric flow controller VM-PRO works independently without requiring additional energy. The central, ball-bearing flap is moved by the air current. The control unit with control cam, spring and damper is attached to the outside of the galvanised sheet steel housing. The required volumetric flow is set in-factory. An adjustment of the volumetric flow at a later stage is possible (setting cam on housing). The control unit is protected with a cover. The controller can be assembled in any assembly position. --- Operating temperature: C --- Differential pressure range 50 - Pa --- Housing leakage according to DIN EN 1751, class C The mechanical volumetric flow controller VM-PRO-R-E / VM-PRO-Q-E with actuator is suitable for adjusting the supply or return air volume to varying room occupations. Should this become necessary, it can be done without removing the false ceiling. As-delivered the volumetric flow controllers VM-PRO- -E are set to V min. The controller must be connected on-site to the power supply and then adjusted on-site to the desired controller position. The control unit, including regulating curve, spring, damper and actuator is attached to the outside of the galvanised sheet steel housing. The required volumetric flow is set in-factory. Housing Galvanised sheet steel (standard) (-SV) Galvanised sheet steel with DD coating (-DD) Stainless steel (V2A) (-V2) or (V4A) (-V4) Control damper Aluminium (VM-PRO-R- for NW </=160) Aluminium with DD coating (VM-PRO-R- for NW </=160) Galvanised sheet steel (VM-PRO-R- for NW >160 VM-PRO- Q-) Galvanised sheet steel with DD coating (VM-PRO-R- for NW >160 VM-PRO-Q-) Stainless steel (V2A) or (V4A), optionally to galvanised sheet steel at an etra charge Control unit housing Plastic, halogen-free Stainless steel (V2A) or (V4A) Thanks to the actuator, the volumetric flow controller can be adjusted without problems to the required volumetric flow within the controller range. If a mechanical limitation of the controller range by means of stops is selected for the drive, the following setting values are possible: To avoid unnecessary controller errors, the information given on p. 9 should be observed. The setting values for actuators with constant control can be obtained from the controller settings. In OPEN / CLOSED actuators, the control setting is effected through a mechanical limit. --- Limit stops for a mechanical limitation can only be achieved in the scale ranges 1-7 and 3-10 (see also: controller setting table) For maintenance, service, retrofitting, etc., inspection openings in sufficient number and size must be provided on-site. For room pressure regulation, we recommend electrical volumetric flow controllers VRA or room pressure controllers CRP. No return possible Version: Document: 08/26 Page 3
