Losses within the system are mostly unavoidable. To ensure a smooth operation refilling from

time to time is necessary.

OPERATING PRINCIPLE

Especially in air conditions, cold water systems, solar systems etc. a special medium mixture is

used whereby a simple refill of fresh water is not possible. Multicontrol autofill solo -S forMCA

automatic, amount controlled make-up of special media offers the possibility to refill a certain

amount media mixture out of a storage tank is required.

We recommend our multicontrol -G vessels as storage tanks, but they don‘t have to beMCA

used compulsively. On site already existing vessels can possibly be used as storage tanks,

because the needed vessel connection unit is always included in scope of delivery of the

control unit multicontrol autofill -S. With it the necessary level measurement in theMCA

storage tank as well as a permanent temperature measurement in the stored medium is

realised.

It is distinguished between the following operating modes:

� ”contact controlled” operation:

Thereby control of the -S for example is carried out by a multicotrol pressureMCA

maintenance device. If the level within the pressure less expansion vessel falls below a certain

minimum level an electric contact will request make-up. The make-up pump (M1) supplies

ready mixed system medium out of the storage tank (e.g. -G) to the expansion vessel asMCA

long as it is refilled up to a preset level.

On demand there is the possibility to supply several multicontrol pressure maintenance

devices with make-up medium by one multicontrol autofil device. Thereto a make-up module

is installed in every supplying pressure maintenance device and via a contact each of these

devices can request make-up from the -S.MCA

� ”pressure controlled” operation:

Pressure controlled make-up takes place into the closed system directly. The system pressure

is hold constant by a membrane expansion vessel ( ), nevertheless it can fall by possibleMAG

leaks. Assumed that the proper function of the is given, make-up can be necessary.MAG

Therefore the vessel pressure transmitter (P1) registers the actual pressure in the system and

compares it with the adjusted set point. Decreases the pressure below the set value the make-

up pump (M1) starts. It pumps medium from the storage tank directly into the system. As soon

as the set pressure is reached, the make-up pump (M1) stops.

The make-up amout is recorded by a water meter (Q1) and compared with the maximum

adjusted make-up amount. Is this amount exceeded the make-up stops and the make-up

operation is locked. Only after verification and disengaging by the system support engineers,

make-up can be activated again. Beside the amount controlled operating mode also a time

controlled operating mode is available, which is advantageous in case of known and regular

necessary make-up amounts.

OPERATING PRINCIPLE DETAILS/

Within the storage tank ( -G) a vessel pressure transmitter (Pl1u) for level measurement isMCA

arranged. Level measurement bases on pressure measurement of the medium in the storage

tank. Out of it the filling height (=vessel level) is determined (also not by weight measurement

of load cells at the vessel).

By undercutting a certain minimum vessel level make-up stops to protect the make-up pump

(M1) from running dry. Not before the storage tank ( -G) is filled again further make-up canMCA

take place.

The storage tank is operated as open vessel to avoid negative pressure or overpressure. All

connections are mounted on site, which implicates high flexibility because connection

positions at the storage tank can be adapted to local conditions.

Circulation function

A circulation function is also included and after proper piping to the storage tank it can be

activated in the settings. It offers the possibility to mix longer stored medium to antagonise

settling out different media components at the storage tank bottom.

Therefore in the working hydraulics an electromotive activated switch mixer (Y5) is built in

already. To start the circulation functon it is activated by the electronic control, either in

periodic intervals of directly before any make-up for an adjustment time, depending on the

requirements of our costumer. For this purpose the switch mixer (Y5) is carried out as three way

mixing valve that is adjusted in position ”make-up” by default and moves to position

”circulating” during the circulation process. Thereupon the make-up pump (M1) is activated

and circulates the medium via the switch mixer (Y5) from the tank connection unit back to the

storage tank. Though all parts of the medium are well mixed again and afterwards make-up

can take place.

Medium recirculation

For safety of financial reasons it can additionally be necessary to prevent a leakage of the

particular system medium (e.g. via safety valves,...) and collect it again. For this purpose at the

storage tank -G a connection for a collecting pipe for media recirculation is provided.MCA
