SIEMENS QAA2061D - Electronic Room Thermostat
The SIEMENS QAA2061D is an electronic room thermostat engineered for precise temperature regulation within commercial and residential HVAC systems. This unit integrates a Proportional-Integral (PI) control algorithm to manage 2-pipe or 4-pipe fan coil units and conventional heating/cooling applications, providing direct control over multi-speed fans and valve actuators. It is designed for standalone operation, featuring an integrated temperature sensor and local user interface for zone-specific climate control.
