4 Equipment properties Equipment properties Application The VRC 430 is a weather compensated controller for heating and hot water preparation. "Weather-compensated" means: At low outside temperatures the VRC 430 provides more heating output, and at higher outside temperatures lower heating output. The outside temperature is measured by a separate sensor, mounted outdoors and transmitted to the VRC 430. The room temperature is only dependent upon your preset values. The influence of the outside temperature is compensated for. You can use the VRC 430 to set different room target temperatures - for different times of the day and for different days of the week. In automatic mode, the VRC 430 controls your heating in accordance with these settings (see Fig. 0.1). The VRC 430 can be used for setting daily heating periods for hot water preparation. The VRC 430 can also be used for the control of the following accessories: Circulation pump for the hot water provision in combination with a multi-functional module VR 40 Ventilation unit conventional hot water cylinder Vaillant layer cylinder actostor Second heating circuit using the Vaillant Mixer Module VR 61 Solar system using the Vaillant Solar Module VR 68 Commercially available 230 V components (e.g. valves, cylinder thermostats) The VRC 430 can be operated with the Vaillant remote control VR 81. The VRC 430 can form part of a new heating and hot water preparation installation or can also be retro-fitted into an existing installation. The boiler must have an ebus interface. ebus is a communication standard for data exchange between the components of heating technology.

The boiler is controlled according to the target room temperature, the time programme and other parameters such as e.g. the set-back temperature. Some of these parameters are set by your installer.. The boiler is constantly on and is controlled to achieve the target room temperature. The boiler is switched off. The room temperature is not displayed and cannot be changed. Frost protection is active. The hot water is ON depending on the operating mode and is controlled to achieve the target temperature, see also Chapter 4.4. The hot water is on according to the time programme. The hot water is constantly on depending on the target temperature. The hot water is switched off. The target hot water temperature is not displayed and cannot be changed. Frost protection is active.. Table 4.2 Modifiable parameters in the basic display Operation in the default display h Note! The default display always appears if the mixer module VR 61 (for a second heating circuit) is not connected and the VRC 430 is wallmounted. In the default display (Fig. 4.8) the operating mode for heating and the current room temperature are displayed in the central area. The default display alsoallows you to change the two most important parameters of your heating installation quickly and comfortably: - By turning the left-hand dial you change the operating mode (automatic, manual, off). - By turning the right-hand dial you can change between the actual room temperature and the set room temperature. Th : C Outside Auto 19.0 C VRC 430 Example: Change the room temperature of heating circuit 1 (HC1) Initial condition: You are located in the basic display (see Fig. 4.2). The way you get to the basic display is described in Chapter Turn the right-hand dial until the cursor appears in front of the target room temperature for heating circuit 1 (HC1). Click the right-hand dial. Fig. 4.8 Default display (example) By clicking either dial you can move from the default display to the next screen (Fig. 4.2 basic display). If there has been no operation of the controller for longer than 5 minutes, the display returns to the default display. The input field for the target value is highlighted. Turn the right-hand dial. The value for the room temperature changes by 0.5 C for each index turn of the dial.. When the desired value is reached, click the righthand dial. The new value is saved and the value is no longer highlighted Operating instructions VRC

12 4 Operation Changing the operating mode in the default display Turn the right-hand dial. Operating mode Auto(matic) Manual OFF Meaning The control of the heating circuit takes place in accordance with the guideline of the target room temperature, the time programmes and other parameters, such as set-back temperature and the heating curve. In part, these parameters are set by your installer. The control of the boiler depends upon the set room temperature. The heating circuit is switched off. The set target room temperature is not displayed and also cannot be altered. Frost protection is guaranteed. Instead of the room temperature, the current set room temperature is highlightedd. After a delay of 1 second you can select the new room temperature: Turn the right-hand dial further until the desired room temperature appears. After a delay of 2 seconds, the new room temperature is saved, the temperature is no longer highlighted and the actual room temperature is displayed. Table 4.3 Operating modes for the boiler This is how to do it: Turn the left-hand dial. The operating mode is highlighted. After a delay of 1 second, you can select the operating mode. Turn the left-hand dial further until the desired operating mode is displayed. After a delay of 2 seconds the value is saved and no longer highlighted.. Th : C Outside Auto 20.5 C > Select room temperature Fig Changing the room temperature in the basic display The new room temperature is used instead of the programmed temperature until the end of the current time programme. This duration depends upon the operating mode; see also Chapter 4.4. Th : C Outside Manual 19.0 C > Select operation mode Fig. 4.9 Changing the operating mode in the default display Changing the room temperature in the default display The control of the boiler is according to the set room temperature. The control system ensures that the set room temperature is reached rapidly and is retained at this level. The prerequisite for this is that the selected heating curve corresponds to the conditions and the function room temperature control is activated. 4.4 Changing the target room temperature If you change a target value - either the room temperature or the hot water target value - in the basic display or in the default display, the new value overrides the programmed temperatures.. When in Manual mode, the control uses the temporary temperatures until either the operation mode or the temperature is changed. When in automatic mode, the control uses the temporary temperature until the next time window starts (if you have changed the set target value outside a time window) or until the end of the current time window (if you have changed the set target value within the time window); see Fig Operating instructions VRC 430

13 Operation 4 Room temperature Room temperature Set back temperature 1 Period 08:00 12: Time 4.5 Level for the user, level for the installer The controller VRC 430 has two levels for the display/ entry. Each level has a series of screens in which the parameters can be displayed, adjusted or changed. Level for the user Serves for the display and for the setting/changing of the fundamental parameters. The setting/changing of parameters can be carried out by the user without any special previous knowledge and during normal operation. Level for the installer Serves to display and for the setting/changing of specific parameters and is restricted to the installer. 4.6 Screens in the user level The screens in the user level are arranged in the same sequence as in the following table 4.4. This table shows you which parameters you can adjust and change. Examples of this can be seen in Chapter 4.7 below. This is the way in which the first screen "basic data" of the user level can be reached from the default display: 15 Click with one or both dials. Period You get to the basic display. 08:00 12:00 Time Turn the left-hand dial by one or two points in the clockwise direction. Fig Duration of validity of target value changes (here: Target room temperature The upper diagram in Fig shows a programmed time window (see Chapter 4.7.1) with the associated room temperature (21 C). In the lower diagram, at (1) the value of the room temperature is changed (20 C). The control system uses this value until the start of the time window. From here (2) the control system uses the room temperature of the time window (21 C). At (3) the value of the room temperature is changed (17 C). The control system uses this value up to the end of the time window (4). After the time window, the control system uses the setback temperature (15 C).

In these time windows, the heating system maintains the room temperature that you have selected, the so-called comfort temperature. Outside the time windows, the room temperature is set back. The set-back temperature can also be changed. h Note! If you programme the control to match your lifestyle in the most optimum manner then you will save energy whilst maintaining heating comfort. The way in which the time window is programmed is described in the following example for heating circuit 1. You can define time windows in a similar way for hot water and for a circulation pump. Turn the left-hand dial until the screen programme is displayed. HC1 2 Time programme Mo 1 06 : : C 2 : - : 3 : - : > Select day of week 2, HC1 time Turn the right-hand dial until the cursor is located in front weekday or block of days. Click the right-hand dial.

You can choose: Mo, Tu,... etc. Mo - Fr (Block) Sa - Su (Block) Mo - Su (Block) Confirm the selection by clicking with the right-hand dial. 1, 2 and 3 indicate the "time windows" which you can programme for the selected weekday or block of days. Within the time window (e.g. from 06:00 to 10:40) the heating is on to achieve the associated comfort temperature. Turn the right-hand dial until the cursor is in front the start time of time window 1. Click the right-hand dial. The field is highlighted. Set the start time by turning the right-hand dial. Each step of the dial changes the time by 10 minutes. When the desired start time is displayed click the right-hand dial to save. Fig Screen 2 (example) Operating instructions VRC

16 4 Operation The end time for window 1 should be set similarly. The comfort temperature for time window 1 is set as follows: Turn the right-hand dial until the cursor is in front of the comfort temperature of time window 1. Click the right-hand dial. The field is highlighted. Select the comfort temperature by turning the righthand dial (one step corresponds to a change of 0.5 C). Confirm the comfort temperature by pressing the right-hand dial. h Note! The control supports the user when programming time windows: a) The programmed times can only be chronological. b) A programmed time window cannot overlap an earlier time window. A time window can only be located between 0:00 and 24:00. An existing time window can be deleted as follows: Set the start time and the end of a window to the same time. Note! The time programmes for hot water or for a dhw circulation pump are set in the same way as described for heating circuit 1. For hot water and the dhw circulation pump, it is not necessary to programme comfort temperatures Programming holiday periods For a longer period of time when you are not at home, you can define a lower room temperature. This will save heating energy. The control ensures that the boiler heats up the living rooms only to this room temperature. You can, e.g. set a room temperature of 15 C if you are on holiday from the 10th to the 24th February. In this time period, the living rooms are heated only to 15 C. You can also select the frost protection function instead of a room temperature. Proceed as follows to programme a holiday period: Turn the left-hand dial until you reach screen 7 "Holiday programming for cpl. system". Fig Screen Holiday programming 7 for cpl. system Period: Room temp.: > Set starting day 7 (example) Frost prot. Turn the right-hand dial until the cursor is in front of the start date.

The desired room temperature or the frost protection function are saved and the value is no longer highlighted Heating settings You can enter the following parameters: Set-back temperature Outside the specified time windows, the room temperature is reduced to the set-back temperature. If your installer has set the frost protection function, the set-back temperature will automatically be 5 C. and the set-back temperature will not be shown. Heating curve The relationship between the outside temperature and the required heating flow temperature is represented by a diagram with different heating curves (see Fig. 4.15). Each heating curve (from ) gives a value for the heating flow temperature (vertical diagram axis) for a specific outside temperature (horizontal diagram axis). Fig Diagram with heating curves for a room temperature of 20 C Example: If the heating curve has been set to 1.5, this means that to achieve a room temperature of 20 C the boiler flow temperature will be 57 C when the outside temperature is 0 C. h Note! In a well-insulated property a comfortable room temperature can be achieved even with a flat heating curve. This saves heating energy. Your expert heating technician will provide advice as to which heating curve should be selected.
