Description of the controller/TR devices
The Rosenberg Compact controller series MSD...TR (for standard motors) or RTE/D...TR (for external rotor motors) is especially suitable for the control of room temperature or inlet air temperature in technical ventilation systems.
The control circuit board contained in the compact untroller series is to set the room or inlet air temperature in conjunction with a room sensor and intake air sensor.
The control takes place on a water heat register by the continuous control of the three-way mixing valve. If on the other hand an electric heat register is used, this is controlled at up to four levels by the module controller i.e. the temperature is controlled by switching on and off the individual heating levels.
If two temperature sensors are connected to the control circuit board, the temperature indication can be
switched between the two actual temperature values.
Adjustments to the closed loop controlled systems can be made at the module controller.
Every piece of equipment has a motor protection device.
This guarantees optimum motor protection for motors with thermocontacts or PTC resistor. If the
maximum permissible coil temperature is exceeded, the motor will be disconnected from the mains supply. After the removal of the cause of the fault and with the voltage restored after disconnection from the mains, the control device can only be switched on again if the system is reset.
The equipment contains a master switch so that the entire system can be switched on.
