LSR 25 // Ventilation controller
The LSR 25 controls ventilation based on temperature and thereby directly drives two 230 V 1~ power drives via a shared temperature setpoint. Runtime logging, minimum and maximum opening for side A and B are each independently adjustable – ideal for dual-sided ventilation systems. The temperature setpoint can be freely selected in the range of –20°C to +60°C; on and off cycles as well as hysteresis can be individually configured. An integrated wind cascade switching function and connections for one wind and one rain sensor each (WST 15, RST 65) protect the system in adverse weather conditions. The built-in freeze protection function ("rattling function") prevents the system from freezing in winter. Supplied with plastic housing and integrated temperature sensor.
Options:
- Wind sensor WST 15
- Rain sensor RST 65
- Emergency stop switch TST 25.1001
