6 Temperature controllers for Highflow and 32 Series Bosch recommends the installation of temperature controllers with the Highflow range and the 32 Series. Fault codes displayed on the controller make fault diagnosis as easy as possible. They also allow temperature control accurate to the single degree. 6.1 Highflow temperature controllers Two different types of Highflow temperature controllers are If several controllers are used, Bosch recommends a parallel available: Standard* and Premium.
7 Frequently asked questions (FAQs) u Are water flow restrictors compatible with Bosch hot 32 Series. However, maximum temperatures can be water systems? increased up to 75°C (Highflow range) and 83°C (32 Series), Yes, but they must allow a minimum flow rate of 9 litres if necessary. We recommend that the maximum temperature per minute. should only be adjusted by an authorised person. Please refer to the installation and operation manual.
