Control functions
There are 5 operating modes available. Operating modes 3, 4, 5 can be ordered preconfigured ex works, so no programming or conversion work needs to be carried out on the sensors on site. The rating plate indicates which operating modes are configured.
It is possible to change operating modes, please contact MAICO.
Mode 1 | Speed control (not parameterised ex works). | Speed control, display in % Low flow – % High flow, time-dependent LS/HS speed changeover. Automatic temperature control of the supply air with external compensation. |
Mode 2 | Speed control with CO² sensor; demand-driven (not parameterised ex works). | Speed control, display in % Low flow – % High flow, CO² concentration-based speed control. Automatic temperature control of the supply air with external compensation. (CO² sensor required). |
Mode 3 | Constant pressure control (parameterised ex works). | Constant-pressure operation with variable volumetric flow (VAV control) with supply air control via 1 integrated differential measuring transducer* and slave-connected outgoing air fan. Automatic temperature control of the supply air with external compensation. |
Mode 4 | Constant volumetric air flow (parameterised ex works). | Constant low volumetric flow in m³/h – Constant high volumetric flow in m³/h – Time-dependent speed changeover. 2 integrated differential pressure measuring transducers. Automatic temperature control of the supply air with external compensation. |
Mode 5 | Constant volumetric air flow with CO² sensor; demand-driven (parameterised ex works). | Demand control with integrated CO² sensor. 2 integrated differential pressure measuring transducers. CO² concentration-based constant volume flow control. Automatic temperature control of the supply air with external compensation. |
*Optionally, a second differential pressure measuring transducer can be installed ex works to separate the pressure control between supply air and exhaust air. [Article number: 0043.2792, DS-M45XX-500PA]
