Product data sheet ASV115CF152, ASV115BF152: VAV compact controller for laboratory and pharmaceutical applications How energy efficiency is improved Allows demand-based volume flow control in order to optimise energy consumption in ventilation systems. Differential pressures of as little as 1 Pa can be controlled to allow minimal volume flows for the lowest possible duct pressure and energy consumption. Features • Controlling the return air in fume cupboards and controlling the supply and return air in laboratories, clean rooms, hospital wards and operating theatres using a VAV box or a damper and flow probe. • Static measurement of differential pressure based on the capacitive method of measurement • Can be used in areas with dirty or contaminated return air • Brushless DC motor guarantees minimum energy consumption and a long service life • Electromechanical torque limitation for safe operation • Extremely simple installation due to self-centring shaft adapter • Disengageable transmission for manual adjustment and positioning of damper • Power cable 0.5 m long, 10 × 0.32 mm2, fixed to housing • Integrated second control loop for the following applications:1): • Room-pressure control: can be ideally combined with EGP 100 with symmetrical measuring range • Room temperature control: can be ideally combined with SAUTER Ni1000 sensor and AXS 215S continuous valve actuator • RS-485 bus interface • Up to 31 subscribers in a segment with SLC (SAUTER Local Communication) protocol • Communication within network via BACnet MSTP2) • Very easy programming of the following applications using the SAUTER CASE VAV software:3): • Volume flow control • Room pressure control • Duct pressure control • Flow control for fume cupboards • Adjustable end values of the differential pressure measuring range4) • 50...150 Pa • 100...300 Pa • Efficient control algorithm for fast control loops • Analogue input and output signals to connect the setpoints and actual values for: • Volume flow • Room pressure control • Room temperature control • Duct section pressure control • Control of fume cupboards • Priority control via switching contacts • Zero point can be calibrated Technical data Power supply Power supply5) Power consumption during operation Approx. 15 VA (10 Nm) Power consumption when idle6) Application support depending on hardware and software version in CASE VAV manual 7010022001 Support of BACnet MSTP interface depending on hardware/type Application support depending on hardware and software version in CASE VAV manual 7010022001 Available measuring ranges depending on hardware/type 24 V=: Analogue inputs that are not connected are rated 0 V. The nominal torque is achieved within the specified tolerances. Terminal 02 cannot be used with 24 V= power supply. Holding torque approx. 5 N

Product data sheet tion of these applications and their functions using the CASE VAV software is described in the document 7010022001. Functions of the ASV115 (existing functions depending on application or selected type) Digital inputs (DI04 and DI05) Priority control can be implemented using the available digital inputs. Individual functions can be selected easily using the software. The digital inputs can be operated with normally-closed contacts or normally-open contacts. A mixture of NC and NO contacts can be used. Minimum and maximum volume flow (mmin and mmax) of the VAV controller command...

Product data sheet Temperature actual value (Ni1000) The temperature is measured by an Ni1000 sensor connected to terminal 04. The measuring range of the temperature input is 0…50 °C. Actuator positioning signal (AO02) A continuous valve actuator can be activated via analogue output 02. The output signal relates to the corresponding sequence of the temperature controller and can be configured freely or as a 0…10 V, 2…10 V signal. Note This function is only available with a power supply of 24 V~. Sensor technology The measuring element in the VAV compact controller is a static twin-membrane sensor...
