It was specifically developed for hidden installation in false ceilings voids. Like all mechanical ventilation heat recovery units by PAUL, it features the highly efficient counter-flow channel-type heat exchanger (protected by German and European patents). Due to its flat design and its different specifications, the unit is particularly well suited for the renovation of large flats, offices etc. The concealed installation in false ceilings allows renovated structures to be provided with a comfortable ventilation system in a space-saving and visually preferable manner. For this type of application, Paul Wärmerückgewinnung GmbH can supply a service hatch tailored to the specific needs of the customer. Air flows can be varied by means of two energy-saving electronically commutated 8 VDC radial fans. The MVHR unit can be equipped with a manual control or an automatic control, depending on customer requirements. The manual control is a membrane keypad, which can be integrated into the PEHA switch system. The membrane keypad provides 7-step flow control, balancing, ing out, supply-only or extract-only (summer ventilation), filter watchdog function and automatic frost protection. An additional boost button and a week timer can be connected, and the unit can be set-up to work with fireplaces (optional extra). The automatic mode allows the flow rate to be adjusted in steps. Fan power of the steps can be varied in % increments. Moreover, the freely programmable control system makes is possible to preset operating times for ventilation at the desired rate; 8 timing programs are available. Alternatively the fan speeds can also be controlled by hand. The standard functions include filter monitoring, intake/ exhaust balancing, frost protection for downstream hot water back-up duct heater, connection of several boost switches and a special standby circuit with a power input less than W. Possible options are: constant-flow control (e.g. for fireplace mode), regulating either a ground to heat exchanger valve or a ground to brine to frost protection, controlling an electric frost protection heater, a back-up duct heater, or a heating circuit pump, and connection of several programmers. The Paul MVHR unit is a fully soundproofed and heat-insulated design with no thermal bridges. The intake is cleaned via a G filter or, optionally, F8 pollen filter. On the extract side, a G-class filter protects the MVHR unit from contamination.

15 COMPAKT DC HEAT RECOVERY VENTILATION UNIT WITH INTEGRATED HEAT PUMP FOR VENTILATION, HEATING AND HOT WATER SUPPLY External programmer with room temperature sensor dimensions (LxWxD in mm): x7x Touch screen directly at Compakt unit dimensions (WxH in mm): 9x PRODUCT DESCRIPTION The compakt DC MVHR unit in connection with the PAUL heat accumulator forms a complete system for ventilation, heat and hot water supply in Passiv Haus and low-energy houses. The ventilation module of the unit supplies fresh into the building and extracts the stale. The intake is in is passed through a ground to heat exchanger, in order to preheat the intake in winter and provide gentle cooling in summer. A ground to heat exchanger bypass valve allows for direct fresh inflow. The heat pump module is an to water heat pump. Its smoothly running fully hermetic low-wear scroll compressor generates the heat transferred to the accumulator by means of water as thermal transfer fluid. The accumulator module is a non pressurised hot water tank design. It provides heat storage for both heat and hot water supply. Optionally, it can be equipped with a stainless steel corrugated tube heat exchanger for use of solar thermal energy and with an electric emersion heater. The compact unit includes a microprocessor control unit for fully automatic regulation. It has controls directly on the unit as well as an external programmer. The compakt MVHR unit is available in a right-handed or left-handed design. PAUL MICROPROCESSOR CONTROL FEATURES constant-flow regulation of ventilation fans ventilation steps, continuously adjustable in % increments ventilation time programs, freely programmable, for normal and holiday operation boost function with adjustable duration filter replacement indication (monitor) fully automatic regulation of summer bypass valve recording of temperature in ground to heat exchanger fully automatic regulation of ground to heat exchanger bypass valve regulation of electric frost protection heater heat pump regulation with automatic thawing function and starting current limitation automatic room temperature regulation weather dependent heating circuit control with freely adjustable night-time reduction speed-controlled outputs for circulation pumps control of flow limitation valve for hot water duct heater heating of supply with temperature limitation regulation of hot water / accumulator temperature with reduction mode quick charging control for accumulator automatic start of electric emersion heater with dynamic control solar control with variable-speed pump output dialogue-type clear text display self-diagnostics and system test manual program for testing of all inputs and outputs (service level) selectable indication of measured and controlled values statistics for all switching processes and operating modes printer output for data reports (RS serial) port for large displays for presentations PC connection for archives (VISUAL )
