End User Handover

At Evinox it has always been our philosophy to provide our customers with a complete service, from the design stage right through to completion.

As part of this service we can offer the developer an end user demonstration subject to service plan contract being in place. This will ensure the end user gains the maximum benefits from our energy efficient products and the boiler programmes are set up to suit the client’s lifestyle. Together with this we provide a simple end user guide.

Your Evinox boiler is one of the most up to date appliances available, designed for maximum comfort, efficiency and reliability. Evinox is a world leader in condensing boiler technology with over 25 years of experience in this field.

Like all gas appliances, it is important that the boiler is serviced annually in accordance with our instructions. It is also a vital condition of our warranty. Details of our own manufacturer’s servicing scheme are enclosed together with contact details.

Service Procedures

1. Your boiler must be serviced every 12 months to validate the warranty and to ensure compliance with your household insurance.
2. The full servicing procedures are detailed within the enclosed manuals.

At Evinox, we have our own Service Division to service and maintain our equipment. This service ensures that, as the end user, your system is always reliable and that you are maximising the energy saving technology within our equipment. Our engineers will carry out the full annual service and provide combustion print out reports and take a water analysis.

Once the system is 10 months old we will contact you with a view to providing you with our set price servicing scheme to provide an annual service and any other attendance.

System Description

The system consists of a high efficiency gas fired condensing boiler and fast recovery hot water tank, designed to maximise your fuel efficiency, provide a large amount of hot water and maintain high levels of home comfort.

The boiler has a built-in microprocessor, which enables you to programme in your heating times, your room temperature set point and hot water temperature. The microprocessor also uses information on the outside air temperature and heat loss and heat gain of the building to vary the power output of the boiler so it is perfectly matched at all times to the heat required within your home, therefore using only the minimal amount of energy.

The heating system design is based on an average temperature being provided to the whole home. The radiators, if fitted, will operate at a low temperature; this provides low temperature safe radiators.

You will notice that the radiator temperature varies. On mild days the radiators may only be luke warm and the temperature of the radiators increases as the outside air temperature goes down.

Terminology

Within our manuals you will see the following terminology, which we have explained for you below.

Optimised start/stop: This function is not available if your programmer is installed in the utility room or a cupboard. If your programmer is installed in the living space or hallway this function will be active. This function allows you to set the times on the controller for the actual times you would like the home warm. You do not have to build in any warm up time. The internal and external sensors feed information to the boiler microprocessor, which stores this in calculations. This data enables the boiler to know how long it takes the home to heat up and how long it can retain heat for. So, on a mild day it may come on 15 minutes before the set time and on a really cold day up to two hours before to ensure your home is warm at occupancy time. At the end of the day the boiler will shut down early if it feels it can maintain the temperature up to the programmed off time.

Weather Compensation: This function varies the boiler output based on the outside weather conditions. We monitor the outside temperature and as the outside air temperature increases the heat requirement of the building reduces so we supply less heat from the boiler to match the homes needs.

Customer Operation and Use: All the customer settings for the heating and hot water temperatures and programmes are carried out on the master programmer controller, the QAA73.

On your QAA73 master programmer you can programme the following:

• Hot water temperature
• Day time temperature
• Night time temperature
• Day of week and time settings
• 3 on/off periods per day
• Holiday period setting

You can also read the actual room temperature, outside air temperature and hot water temperature.

Control of the heating: For highly insulated new homes the off temperature or unoccupied temperature (reduced as we know it) should be set about 12 -14ºC, as the building integrity should retain the heat in the home during the reduced temperature period.

Room Temperature: This is set on the golf ball dial of the programmer (set point knob) when the cover is closed you simply turn the knob up and down to increase the room temperature by increments of 0.5ºC. Turn up the whole house temperature at the programmer (QAA73) golf ball if you need more heat and this will increase the flow temperature to the heating. If you feel that the whole house temperature is too high you can turn the golf ball dial down.

As our QAA73 controller is the master controller it means that all other thermostats are slaves. This means that the master dictates to the slave and the slave cannot dictate to the master. So, if you require the hottest room in your home to be 23°C then you need to set the golf ball dial on the QAA73 to 23°C, you then control other rooms back from this point. You cannot, for instance, set the QAA73 at 21°C and expect to achieve 23°C in a slave room.

Note: It is important that any temperature changes are gradual. There is a tendency with UFH to turn the golf ball all the way up as the change in temperature is not as quick as with radiators. However, we would always encourage you to only turn the dial up or down 1ºC a day to find the temperature that suits you best. Once you find this level you will find that you never need to adjust the set point again no matter what the weather conditions are.

Individual rooms: can be controlled by the use of thermostatic radiator valves if fitted to the radiators or the individual room’s thermostats located in the rooms. If you want some rooms cooler than others turn the thermostat down in that room.

Individual Room Thermostats: If supplied by Evinox these will be Siemens RDD.10 digital room thermostats. These will simply control the room temperature within the room they are installed in. You simply press the + or – button to increase or decrease the room temperature set point. As described earlier you cannot have these set higher than the master controller.

Programming: The Programmer (QAA73) uses a scrolling screen principle. This is a common feature now being used in a wide range of controllers and is the same control principle used on mobile phones.

You simply have an up and down arrow to scroll to settings known as the line selection buttons and then a minus and plus button to change the settings known as the setting buttons.

On page 11 you have a list of parameters that can be set or changed, these are numbered 1 through to 50.
