Both ofthem enable you to create a visual impression of theprocesses in your control system and influence them atany time. The programmes enable you to record andgraphically prepare system data, to load device configu-rations and change and save them online and to save in-formation in the form of reports.Using vrDIALOG 810/2, you can make all the settings forthe heat pump as well as other settings for optimisation.Settings via vrDIALOG may only be performed by an ex-perienced specialist.Parameters Description Factory settingCalibration of temperature sensors Internal sensors can only be calibrated via vrDIA-LOG 810/2.Change name: CH circuit A maximum of tenletters are available per heating circuit for this purpose. Amaximum of ten letters are available per heating circuitfor this purpose. The selected names are saved automati-cally and displayed on the corresponding displays.Depending on the system configuration, the names of ad-ditional heating circuits appear in the display.HK2: Software version The status provides information about the operating stateof the heat pump software.—Elec Tariff switch Status of power interruption due to activation of the EVUcontact (blocking initiated by the power company):"no" = no blocking, "yes" = blocking active, activation bymeans of e.g. ripple control signal/receiver.—Starting current limiter Soft start status: ON/OFF —Fixed value dayFixed value nightThis display only appears if the setting Type "Fixed value"has been selected via vrDIALOG.Here the flow temperature is controlled around a fixedsetpoint, independently of the outside temperature.Fixed value day: Flow setpoint temperature (e.g. for ma-nually set screed floor drying).Fixed value night: Flow setpoint temperature at night.35 °C30 °CType HK2 Setting the heating circuit type:– Direct circuit: (Hydraulic plan 3) Heating mode runswith the setpoint flow temperature determined by theweather-controlled energy balance controller.– Mixer circuit: (Hydraulic plan 4) Heating mode runswith the setpoint flow temperature determined by theweather-controlled controller.– Fixed value: Fixed settings for the setpoint flow tempe-ratures for day and night; see Menu C5.direct circuitTable 8.7 Parameters that can be set with vrDIALOG 810/2Control system 8
