Roth regulation unit BW
Roth regulation unit BW is equipped with a microprocessor operated temperature difference regulation unit for heating domestic water and contains all of the basic regulation functions required for safe and efficient operation of a solar system. 2 PT-1000 sensors are included in the delivery. The simple and easy-to-understand operation of the regulation unit is carried out through the use of 4 control elements (3 buttons). Improved ease of operation thanks to self-explanatory graphic symbols and the lighted system monitoring
display. The solar circuit can be operated automatically or in manual mode. The Roth regulation unit BW has 1 output (1 x speed controlled) and 4 temperature sensors.

Roth regulation unit BW/H
Roth regulation unit BW/H is a microprocessor operated temperature difference regulation unit with wide applications that was designed for heating domestic water and supporting heating systems. It contains all basic control functions in addition to selectable special functions for facility optimisation. 3 PT-1000 sensors are included in the delivery. The installation information is shown on the lighted system monitoring display with self-explanatory symbols. The Roth regulation unit BW/H has 2 outputs (1 x speed controlled, 1 x on/off) and sensors as well as 1 impulse input for measuring quantity of heat, 9 installation schemes pre-installed.

Roth regulation unit BW/H Komfort
Roth regulation unit BW/H Komfort is a microprocessor operated temperature difference regulation unit with a lighted display with wide applications that was specially designed for the combined purpose of heating domestic water and supporting heating systems. It is equipped with all basic control functions in addition to selectable options for facility optimisation heat meter. Optional data stick to save and read operating and measured values, PC interface. 3 PT-1000 sensors are included in the delivery. Selection of installation designs makes it possible to have simple initial start-up of the regulation unit and to carry out practically all solar thermal applications. The Roth regulation unit BW/H Komfort has 12 sensor inputs, including 2 impulse inputs for measuring quantity of heat, 1 input for optional sun sensor and 9 relay outputs (4 standard, 4 solid state relays for speed control and 1 potential-free relay e.g. for the activation of the boiler).
