6.8.2 Set-back operationIn all systems with DHW heating and at least one heating circuit with control valve, DHWheating can be given priority by applying set-back operation. With the settingCO4 -> F08 - 1, the charging temperature can be monitored in the DHW circuit. In systemswithout the sensor VFx in the DHW circuit (e.g. Anl 4.5, 11.0, 12.0, 13.0, 21.0), the tem-perature directly at the storage tank sensor SF1 is monitored. If system deviations still occurafter the time forActivate priority in case of deviation has elapsed, the set point of the heat-ing circuit or supplementary heating circuit – with several possibilities Rk3/Y3 – is set to re-duced operation.Functions WE ConfigurationPriority through reverse control CO4 -> F08 - 0Priority through set-back operation 02 minCO4 -> F09 - 1Activate priority in case of deviation / 2 to 10 min6.9 Forced charging of the DHW storage tankTo provide the full room heating performance when the time-of-use of the heating circuits be-gins, existing storage tanks are charged one hour before the time-of-use of the heating cir-cuits starts.For the individual controller, this means that storage tank charging is activated when the wa-ter temperature in the storage tank falls below the adjusted deactivation value of T =DHWtemperature +hysteresis. The forced charging of the storage tank does not take place whenthe DHW circuit is not used at the beginning of the time-of-use set for the heating circuit(s).Note: This function is not available when a storage tank thermostat is used.6.10 Thermal disinfectionIn all systems with DHW heating, the DHW storage tank is thermally disinfected on a se-lectedDay of the week or every day.4 In systems with DHW storage tank, it is heated up, taking into account theCharging tem-perature boost parameter (orSet point boost, depending on the system) to the adjustedDisinfection temperature. Disinfection begins at the adjustedStart time and, at the latest,ends at the specifiedStop time.4 In systems with DHW heating in instantaneous heating system, the function remains activetaking into account theSet point boost parameter until the circulation pipe, measured at92 EB 5579 ENFunctions of the DHW circuit
