Bosch Greenstar CRC100 Comfort Room Control

The CRC100 can be used for a heating system with one heating zone. This method of operation is used when the CRC100 is connected directly to the heat source. This will modulate the percentage of power output the heat source is supplying. The CRC100 can be used for one heating zone with a CZM100. A maximum of 8 heating zones is permitted when connected to several CZM100 Comfort Zone Managers. The CRC100 can be used as a controller for heat sources with an external indirect tank and circulator pump, but the DHW maximum temperature and priority settings are made at the heat source.
