Arrangement for visualizing supply and return temperature characteristic curves in remote heating stations, to project and store supply and return temperatures as function of external temperature

摘要

Memories (17,18) store daytime and nighttime values, which are directed to auxiliary memories (19,20), and then to comparators (21,22). The output values of the comparators are arranged on an associated long term memory (23,24) according to the associated external temperatures. A changeover selector switch is provided for the long term memory outputs, which are further output to an indicator (27) across a graphic generator (26). An Independent claim is included for a method for using the arrangement.
