To ensure compliance with this new standard the following details are included. The following information is intended to help you throughout the boilers entire instruction pack. We assume no liability for any damage caused by non-observance of these instructions.
2 Safety 2.3 Safety instructions Always observe the following safety instructions and regulations. Danger Inflammable mixtures of gas and air may explode. Do not use or store explosive or easily flammable substances such as petrol or paint in the same room as the appliance. Danger Risk of poisoning and explosion due to a malfunction. Never put the safety devices out of operation or tamper with them so as to impair their function. 2.
Instructions on operation 3 3 Instructions on operation 3.1 Factory guarantee 3.1.1 Two 2 year guarantee for ecoTEC plus appliances Vaillant undertakes to rectify any manufacturing defect that occurs within twenty-four months of the installation date. For the 2nd year of the guarantee to be valid an annual service must be carried out by a CORGI registered installer one year after installation. The cost of this annual service is not included in the guarantee. 3.1.

Operation 4 Hot water supply active (ecoTEC plus combination boilers only) Illuminated: Hot water demand 10 Maximum radiator temperature control 11 Maximum hot water temperature control and warmstart ON/OFF (ecoTEC system boilers only) Illuminated: Heating of an indirect hot water cylinder turned on Flashing: Heating demand from the hot water cylinder, burner on Multifunctional display system ecoTEC pro boiler has a multifunction display (1).
4 Operation 4.3 • On ecoTEC combination boilers only: Ensure the cold water service valve (2) is open. This can be checked by opening a hot water tap and ensuring water flows. Initial checks before turning on 4.3.1 Opening the service valves Note If a bottom cover is fitted to the boiler the service valves are behind this cover. Caution The pressure relief valve is provided for safety reasons and must not be interfered with. 2 4.3.
Operation 4 Note Your appliance has a pressure sensor. If the pressure falls below 0.6 bar the pressure flashes in the display. If it falls below 0.3 bar the appliance switches off. The error message F.22 appears in the display. The system must be filled with water before you start up the appliance again. 4.5 Domestic hot water with ecoTEC combination boilers The boiler must only be used when the heating system contains water (see 4.3.2). 4.5.1 Setting the water temperature plus 4.
4 Operation 4.5.2 Switching the warmstart function on and off The warmstart system of the ecoTEC combination boilers provides you with hot water at the required temperature immediately. To do this, the hot water heat exchanger of the ecoTEC is kept at a pre-selected temperature level and the boiler will therefore periodically operate to maintain this temperature. ecoTEC pro: 1 b a ecoTEC plus: 2 1 b b a c 1 b c 1 Fig. 4.
Operation 4 4.6 Heating operation 4.6.2 Switching off heating (summer operation) The boiler must only be used when the heating system contains water (see 4.3.2). plus pro 4.6.1 Setting the maximum radiator temperature control plus pro i F P 2 1 1 bar i F Fig. 4.14 Switching off heating (summer operation) P bar You can switch off the heating in summer without switching off the hot water supply. • Turn the knob (1) for setting the maximum radiator temperature all the way to the left. 4.6.
4 Operation The boiler will now operate automatically to provide central heating for the conditions selected on the external controls (ecoTEC combination boilers will also provide domestic hot water on demand). After the boiler stops operating the pump will continue to operate for a short period to fully disperse the heat from the boiler.
Operation 4 4.8.1 Problems due to low system water pressure The device switches to “Fault” if the water pressure in the heating system is too low. This malfunction is indicated by the fault code “F.22” (dry fire) or “F.23” or “F.24” (lack of water). You can only start up the appliance again when the heating system is sufficiently filled with water. 4.9 Turning off the boiler i F P 4.8.2 Ignition problems plus 1 pro bar 2 1 Fig. 4.
4 Operation 4.10 Frost protection The frost protection feature only protects the boiler. Any other parts of the system liable to frost damage should be protected accordingly. Caution The frost protection and monitoring systems are only active when the main ON/OFF control of the appliance is in the “I” position and it is not disconnected from the main power supply. Frost protection function The boiler has a frost protection function.
