53Operating manual for the auroMATIC 620 0020094404_00 Controller

Operating mode

Using the operating modes you determine how your

room heating or hot water generation is controlled.

Operator level

The Operator level displays the basic parameters which

you can set/change without any special prior knowledge

during normal operation. You can adapt your heating

installation to your needs by setting the parameters

accordingly.

Parameters

Parameters are the operating values of your heating

system.

You can set these operating values by, for example,

changing the Night set back temperature parameter

from 15 °C to 12 °C.

ProE system

The Vaillant ProE-System enables quick, problem-free

and irreversible connection of accessories and external

system components to the appliance's electronics.

Protection class

Protection class denotes the classification and identifi-

cation of electrical equipment with reference to the

existing safety measures to prevent electric shocks.

Room temperature

The room temperature is the temperature actually

measured in your apartment.

Secondary return

If there is a large distance between the hot water

source and the draw-off point (e.g. sink, shower or kit-

chen sink) cooled-down hot water will first run from the

long pipe until hot water is present again. For that rea-

son a secondary return is laid parallel to the hot water

pipe in installations with long pipe runs. A pump keeps

the hot water circulating constantly. Thus hot water is

immediately available, even at remote draw-off points.

Time controllers are used to conserve energy.

Set-back mode

In set-back mode, a system is operated at a somewhat

lower temperature, speed, etc., than usual, e.g. set-back

mode of the heating installation. A suitable controller

can be used here to lower the room temperature, e.g.

during absence or overnight.

Set values

Target values are desired values that you specify in the

controller, e.g. the room target temperature or target

temperature for water heating.

Solar-assisted heating:

Apart from heating drinking water, solar heating

systems can also be used to assist heating. To this end,

the solar system is made with a combi or buffer cylinder

and correspondingly larger collector surface. Free solar

energy can thus supply the necessary heating heat

during the transitional periods (spring and autumn). On

sunny winter days the solar system supports the heater

and thus helps to conserve fuel.

Heating systems with low operating temperatures such

as, e.g. underfloor heating, are particularly suited to

solar assistance.

Solar collector

Solar collectors convert solar radiation into useful ther-

mal energy for hot water supply and heating assistance.

The solar energy is taken up by the absorber in the coll-

ector, which transfers the radiant heat to the solar cir-

culation. The solar circulation, which carries solar fluid

(heat transfer fluid consisting of a water–glycol mix-

ture), transports the heat from the collector to the solar

cylinder.

Solar collectors can be constructed as flat or vacuum

tube collectors. Vaillant auroTHERM classic flat collec-

tors consist of a flat absorber with a cover of patented

anti-reflection glass. The 'Blue Shine' effect gives the

flat collector a distinctive visual appearance.

Solar cylinder

Regardless of whether the solar heat is used for hot

water generation or for solar-assisted heating:

In both cases it is stored temporarily in a solar cylinder

or a buffer cylinder so that the heat is also then availa-

ble when the sun is not shining directly. Different confi-

gurations are used depending on the version of the

solar thermal energy system. Bivalent DHW cylinders, to

which an additional second heater can be connected,

are used predominantly for solar heating of drinking

water. For solar-assisted heating, the heat is stored in a

buffer cylinder, e.g. an MSS cylinder. Combi storage

tanks are suitable for the combination of drinking water

heating and heating assistance.

Solar gain

The energy obtained by a solar system in a defined

period (usually one year). For solar thermal installa-

tions, the term means the useful solar heat that can be

extracted as heat from the solar cylinder and for photo-

voltaic installations, the useful electrical energy.
