  • Page 4: General

    1. General The digital heating and district heating controller TROVIS 5430 is for weather-sensitive flow temperature control of heating systems, i.e. by way of a heating characteristic the flow tempera- ture of a heating loop is regulated in such a way that the desired room temperature is adjusted, independent of the outside temperature.

    2. Installation 2.1 Installing the controller The controller consists of the controller housing with electronics and a housing rear panel with terminal strips. The housing rear panel can be ordered as a flat or deep version. To connect electrically, the front screws must be loosened and the controller housing must be se- parated from the rear panel.

  • Page 11: Description Of Controller Functions

    4. Description of controller functions The following function descriptions are intended to assist comprehension of the settings required for operation. The controller functions depend on the selected system code number, 1, 2, 3, or 4, depicted and described in chapter 5. The tables on pages 37 and 38 can be used to clarify the configuration levels (CO) and function blocks (FB) described in the function descriptions.

  • Page 12: Flash Adaptation

    4.2 Flash adaptation It is possible to achieve a direct reaction to deviations in room temperature via the function block setting CO1 FB 3 = EIN (linked to FB 1 = ON): so-called flash adaptation counteracts deviations in room temperature within time-controlled rated operation by raising or lowering the heating characteristic by up to 10 °C (parallel adjustment of the heating characteristic).

  • Page 13: Delayed Outdoor Temperature Adaptation

    mertime operation commences on the second day. If the daytime mean temperature level falls below the outdoor temperature limit on two successive days, then summertime operation is ter- minated on the following day. 4.5 Delayed outdoor temperature adaptation A calculated outdoor temperature is used to determine the flow temperature. This delayed adap- tation occurs a) only if the outdoor temperature falls, or b) independent of outdoor temperature variations.

  • Page 14: Thermal Disinfection Of Drinking Water Storage Tank

    4.8 Thermal disinfection of drinking water storage tank This function cannot be used in conjunction with a storage tank thermostat. On all systems with heating up of drinking water the function block setting CO2 FB 5 = ON cau- ses the storage tank to be charged at 75 °C every week on a selected day at 0000 hrs. The heat exchanger charging pump TLP is immediately switched on, regardless of the flow tem- perature values which have been measured.

  • Page 15: Buildup Of Charging Temperature Via The Return Flow Sensor With

    4.10 Buildup of charging temperature via the return flow sensor with the heating loop switched off This function is only active with system code number 2. If, during the usage period, the heating loop is switched off, then in the case of storage tank charging the storage loading pump is only switched on when the temperature at the return flow sensor attains the temperature level measu- red at storage tank sensor 1.

  • Page 16: Sensor Failure/Operation Errors

    4.15 Sensor failure/operation errors Interruptions or a short circuit of the sensor lines as well as other operational errors are display- ed in the operating level by an ”ERROR” message. If this level is opened, then the controller indi- cates the defective sensors by corresponding combinations of symbols. Operational errors are displayed using the following number codes: Err 1: New reading in of cold start values.

  • Page 17: Monitoring Of A Flow Maximum Temperature For Heating Up Of Drinking Water

    4.18 Monitoring of a flow maximum temperature for heating up of drinking water If heating up of drinking water with master switchover is selected (possible only on system code number 3), the controller monitors the flow temperature at the flow sensor for the heat exchanger during storage charging.

  • Page 18: System Diagrams

    5. System diagrams Preliminary remarks: The system diagrams depicted contain only the system components relevant to the control, not however safety relevant system components. If a temperature regulator (TR) or a safety temperature monitor (STW) or additionally a pressure limiter (DB) is required, a control device with a safety function according to DIN 32730 must be used.

  • Page 22 D) Summertime operation or switched off operation A drinking water requirement leads to an immediate buildup of the charging temperature via the storage tank, i.e. the SLP is switched on. The ZP runs according to the function block setting. If CO2 FB 8 = ON, then the SLP is only switched on when the temperature at sensor RüF is higher than the temperature at sensor SF1.
  • Page 23 At 5K above the charging setpoint value (measured at flow sensor VF), at the latest after three minutes, the changeover valve begins to conduct the heating medium in the direction of the storage tank. The UP must continue to run for storage tank charging! The ZP runs according to the function block setting.
