1 1 Notes on the installation instructions Notes on the installation instructions The following instructions are intended to guide you throughout the entire documentation. Further documents apply in combination with these installation instructions. We accept no liability for damage caused by failure to observe these instructions. 1.1 Observing other applicable documents > Always observe all installation instructions for parts and components of the system when installing the VRC 470f controller.
Safety 2 2 Safety 2.1 2.2 Safety and warning information > When installing the VRC 470f, take account of the basic safety instructions and the warnings that may appear before an action. 2.1.
2 Safety Protecting against legionella The controller is furnished with an anti-legionella function to protect against infection by germs (legionella). When the function is activated, the water in the domestic hot water cylinder is heated to over 60 °C for at least one hour. > Set the anti-legionella function when installing the controller. > Explain to the operator how the anti-legionella function works.
System description 3 3 System description 3.1 3.2 System design The VRC 470f controller controls the Vaillant heating and hot water systems. You can fix the controller to a wall using the wall-mounting base. You can mount the radio receiver unit on a wall using the wall-mounting base or in the controller slot of a Vaillant boiler, without the wall-mounting base. 1 2 3 4 Fig. 3.

Start-up 6 6 Start-up When you start the controller for the first time after electrical installation or after replacement, the Installation assistant starts automatically. The installation assistant helps you to enter the most important settings for the heating system. The operating concept, an example of operation and the menu structure are described in the operating instructions of the controller (¬ Operating instructions).
6 Start-up 6.2 Making settings for the operator Make the following settings for the operator via the Operating level: > If DCF77 reception is not possible, set the date and time. > If necessary, change the factory-set designations of the components in the heating system. > Set the mode for the heating function. The mode for hot water production is dependent on this and cannot be set separately. > Set the target room temperature ("Desired day temperature").
Operation 7 7 Operation The menu structure, the operating concept and an example of operation are described in the operating instructions of the controller (¬ Operating instructions). The controller has two operating levels, the Operator level and the Installer level.

Description of functions 8 You activate this function by setting an offset (in K). The controller activates summer mode when the outside temperature is greater than or equal to the current target room temperature + the set offset value. The target room temperature at night, for example, is the set-back temperature. The controller deactivates summer mode when the outside temperature is less than the target room temperature + the set offset value - 1 K. 8.4.

This function allows you to define the target temperature for a connected domestic hot water cylinder ("desired hot water temperature").
Description of functions 8 When cylinder charging ends ("desired hot water temperature" reached), the controller switches the boiler off. The run-on time for the cylinder charge pump starts. The controller automatically deactivates the cylinder charge pump after the run-on time has elapsed. If a VIH RL cylinder is connected and if the cylinder is connected directly to the boiler, the function has no effect. 8.6 i 8.6.1 8.5.

Fault detection and elimination 10 10 Fault detection and elimination 10.1 Error messages If a fault occurs in your heating system, an error message will appear in the controller display instead of the basic display. You can access the basic display again by pressing function key "Back". If the display remains dark or you cannot make any change to the display by pressing the function keys or control knob, there is a system error.
10 Fault detection and elimination 10.2 List of errors 10.3 Menu ¬ Service information ¬ System status ¬ Status [Fault] If there is a fault, the status "Fault" is displayed. In this case, the right function key has the function "Display". Press the right function key to view the list of error messages. i Restoring factory settings You can reset your settings back to the factory settings (¬ Operating instructions). Not all error messages in the list appear automatically on the display.
Replacing components 11 11 11.1 Replacing components Recording radio controller settings i When you replace the radio receiver unit and/ or the radio controller, the user settings will be partially or completely lost. 11.2.1 Removing the faulty radio receiver unit i Before you start, you should make a note of all the settings on the radio controller.
11 Replacing components 11.3 Replacing the outside temperature sensor/ transmitter 11.3.1 Removing the faulty outside temperature sensor/transmitter Fig. 11.2 Removing outside temperature sensor/transmitter > Use a screwdriver to press in the catch at the bottom of the wall-mounting base. > Lift the outside temperature sensor/transmitter upwards and off the wall-mounting base.
Replacing components 11 Fig. 11.3 Remove the cover Fig. 11.4 Remove capacitor 1 Fig. 11.
11 Replacing components 11.3.2 Activating and fitting the new outside temperature sensor/transmitter 1 2 Fig. 11.6 Radio receiver unit controls i Before you activate the outside temperature sensor/transmitter, you must press the teach button on the radio receiver unit to start the teach-in function. The outside temperature sensor/transmitter then has to be activated within the next 15 minutes as the teach-in function automatically terminates after 15 minutes.
Replacing components 11 Proceed as follows: > Pull the controller (1) upwards and off the wall-mounting base (2). > Remove the batteries. > Dispose of the batteries and the radio controller correctly. 11.4.2 Fitting the new radio controller > Insert four new batteries of the same type in the controller. 11.4.4 Radio controller: activating teach-in i Operation of the radio controller is described in the operating instructions for the radio controller.
12 Warranty and customer service 12 Warranty and customer service 12.1 Vaillant warranty We only grant a Vaillant manufacturers warranty if a suitably qualified engineer has installed the system in accordance with Vaillant instructions. The system owner will be granted a warranty in accordance with theVaillant terms and conditions. All requests for work during the guarantee period must be made to Vaillant Service Solutions (0870 6060 777). 12.
Decommissioning 13 13 Decommissioning e For wall-mounting: 1 Danger! Risk of death from live connections! When working in the control cabinet of the boiler there is a risk of death from electric shock. Continuous voltage is present on the mains connection terminals, even if the main switch is turned off! > Switch the main switch off before working on the control cabinet of the boiler.
13 Decommissioning 13.4 Recycling and disposing of the controller, radio receiver unit and outside temperature sensor/transmitter The devices and their associated transport packaging are made very mainly of recyclable raw materials. 13.4.1 Devices Neither the devices nor any of their accessories should be disposed of as normal household waste. > Make sure that the old devices and any accessories are disposed of correctly. 13.4.
Technical data 14 14 Technical data i 14.1 14.2 The range of radio transmission inside buildings is heavily dependent on the local conditions (e.g. the design and structure of the building). Consequently, an indoor range of 25 m cannot always be guaranteed. Outside enclosed spaces (outdoors) the range is more than 100 m.

15 Glossary 15 Glossary Auto_Off In the “Auto_Off mode” (Installer level), in Automatic mode the control functions outside active time periods can be specified separately for each heating circuit. There are three control modes (frost protection, ECO, set-back temp.) available for selection, which can be further adapted through the use of the room temperature control.
Glossary 15 If heating curve 0.4 is selected and 21 °C rather than 20 °C is specified as the target room temperature, the heating curve is displaced as shown in Fig. 2. The heating curve is displaced according to the value of the room target temperature along axis a which is angled at 45°. This means that when the outside temperature is -15 °C, the control provides a flow temperature of 45 °C. Heating flow temperature The boiler heats water which is then pumped through the heating installation.
