4 Operating Manual auroMATIC 560

3.2 Intended use

The auroMATIC 560 solar controller is a state-of-the-art

appliance which has been constructed in accordance

with recognised safety regulations. Nevertheless,

improper use can cause serious or fatal injury to the

user or others, and the appliance or other property can

be damaged.

The appliance is a control system for regulating warm

water storage with solar heating, and supports reheating

with a boiler or with an electric heating rod.

Any other use or extended use is considered to be

improper. The manufacturer or supplier is not liable for

any resulting damage. The user alone bears any risk.

Intended use includes the observance of the operating

manual and all related documents.

Caution!

Any improper use is forbidden.

3.3 Requirements for the installation site

The controller must be installed in a dry room.

3.4 Care

You can clean the housing of the controller with a damp

cloth and a little soap.

Note!

Do not use scouring or cleaning agents which

could damage the display.

3.5 Recycling and disposal

Neither the controller or any of its accessories belong in

the household waste. Make sure the old appliance and

any existing accessories are disposed of properly.

4 Functions

4.1 Solar yield

The solar controller works on the principle of differential

temperature control. The controller always switches on

the collector pump when the difference in temperature

(collector temperature - cylinder temperature) is greater

than the programmed activation difference.

The controller switches off the collector pump when the

difference in temperature (collector temperature - cylin-

der temperature) is less than the programmed activation

difference.

The heating engineer sets the parameters to the install-

er level when the solar controller is installed.

The solar yield is determined from:

– The difference in temperature between the collector‘s

forward flow and return flow

– The set flow value at the control valve of the flow rate

limiter (set during installation)

– The operating time of the collector pump

During installation the heating engineer sets the flow

rate limiter and enters the flow rate into the solar con-

troller at the installer level. The solar yield is calculated

by the solar controller. The total yield can be called up

and reset in the installer level.

4.2 Reheating

The reheating function allows the cylinder to heat up to

the required temperature during a set time window, even

if the solar energy yield is insufficient. In this case the

water can be reheated using an external heater or an

electrical heating rod. You can set up time windows for

reheating the solar cylinder (see Sec. 5.5.3 for details).

4.3 Reheating delay

To prevent unnecessary reheating by an external heater

or an electrical heating rod, the controller is equipped

with a reheating delay function. This function delays

reheating by up to 30 min. in case the collector pump is

running and the solar yield becomes available. If the col-

lector pump remains off and/or the desired cylinder tem-

perature is not reached after the delay period, the cylin-

der will be reheated using the external heater or electi-

cal heating rod.

The reheating delay function is activated in the expert

level.

4.4 Connecting a second storage cylinder

You can connect up to two solar cylinders to the control-

ler. The cylinder with the higher maximum temperature

will be considered as the priority cylinder. The priority

cylinder will always be heated if the collector tempera-

ture is greater than than actual temperature plus the set

activation difference. The heating of the the cylinder will

stop once the maximum temperature for the cylinder is

reached, or if the collector temperature is less than the

actual cylinder temperature plus the set activation dif-

ference.

The second cylinder can only be heated when the first

cylinder is not being heated. The same activation and

deactivation conditions apply here as well.

4.5 Anti-Legionnaire’s disease protection

The anti-Legionnaire‘s disease protection function is

designed to kill germs in the cylinder and pipes.

When the function is activated, the cylinder, the corre-

sponding hot water pipes, and the circulation pump (if

installed), are brought to a temperature of 70 °C once a

week (Wednesday, 14:00).

In doing so, the cylinder temperature is raised to 70 °C

and the corresponding circulation pump is switched on

(if installed). First, an attempt will be made using solar

yield alone to reach the target temperature over a

90 min. period. If this is not successful, the anti-

Legionnaire’s disease protection is carried out using an

external heater or an electric heating rod, if one or the

other has been installed for reheating. The anti-

Legionnaire’s disease protection function will stop once
