Operating manual – auroMATIC 560 0020008427_014
Functions 4
4 Functions
4.1 Solar yield
The solar controller works on the principle of differential temperature control system. 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 - cylinder temperature) is less than the programmed deactivation difference.
The expert technician sets the parameters to the installer 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 flow value specified (during installation) at the
control valve of the flow rate limiter
– The running time of the collector pump
During installation the expert technician sets the flow
rate limiter and enters the flow rate into the solar controller 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 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 Section 5.5.3 for details).
4.3 Reheating delay
The controller is equipped with a reheating delay function to prevent unnecessary reheating by an external
heater or an electrical heating rod. This function delays
reheating by up to 30 min. in case the collector pump is
running and the solar yield becomes available. If the collector pump remains off and/or the desired cylinder
temperature is not reached after the delay period, the
cylinder is reheated using the external heater or electrical heating rod.
The reheating delay function is activated in the installer
level.
4.4 Anti-legionella function
The anti-Legionnaire‘s disease protection function is designed to kill germs in the cylinder and pipelines.
When the function is activated, the cylinder, the corresponding hot water pipes and circulation pump (if installed) are brought to a temperature of at least 60 °C
once a week at a specific time on a specific day, or
every day.
In doing so, the cylinder temperature is raised to 71 °C
and the corresponding circulation pump is switched on
(if installed). The anti-legionella function is implemented
either via an external heater or electrical heating rod if
this is used for reheating. The anti-Legionnaire’s disease
protection function will stop once a temperature of at
least 68 °C has been maintained for a period of
30 minutes.
The anti-legionella function is activated by the expert
technician at installer level.
4.5 Pump blocking protection
If no pumping has occurred for 23 hours, all installed
pumps are switched on for roughly 3 seconds to prevent
the pumps from seizing.
4.6 Circulation
If you only have one collector field connected, a circulation pump can be connected to the controller. You can
specify up to three heating windows for the circulation
pump in the timer program (see Sec. 5.5.4). Set up the
time program so that the circulation pump only operates at times when you expect a supply of hot water demand will be needed. Otherwise the circulation pump
operates unnecessarily and inadvertently cools down
the cylinder.
4.7 Calendar
The controller is equipped with a calendar so that it can
automatically adjust for daylight-savings time. To activate it, simply enter the current date in the installer
level.
Note
h
Please observe that in the event of a power
failure the controller only has a power reserve
of 30 minutes. After 30 minutes, the internal
clock stops and the calender will not automatically resume function once power has been restored. In this case the time and date will need
to be reset.
4.8 Activation duration controlling
Activation duration controlling serves to keep the solar
circuit at the activation value, and thus in operation, for
as long as possible. The pump is switched on and off in
periodical bursts depending on the difference between
the collector temperature and lower cylinder sensor.
When the activation difference is reached, the function
is started (if activated) with an activation duration of
30 % – i.e. the pump is switched on for 18 seconds and
then switched off for 42 seconds. If the difference in
temperature increases, the activation duration is prolonged (e.g. 45 seconds on, 15 seconds off). If the difference in temperature falls, the activation duration is reduced (e.g. 20 seconds on, 40 seconds off). The period
length is always a minute. Activation duration control is
activated in the installer level.
5Operating manual – auroMATIC 560 0020008427_01
4 Functions
4.9 Special functions
Please refer to Sec. 5.6 for information on how to activate the following special functions.
4.9.1 Advance
When the advance is activated, the reheating function is
enabled. This means that the set target value for the
cylinder will be maintained by reheating if necessary.
4.9.2 One-time reheating
When this function is activated, the cylinder temperature is reheated to the set level one time.
4.9.3 Holiday function
When this function is activated, the operating mode is
switched to "OFF" for the set holiday period
(1 to 99 days). This deactivates both the solar yield and
the reheating function.
4.10 Cylinder priority
Two solar-charged cylinders can be connected to the
heating installation. You can use the PRIO cylinder priority function to define which cylinder should be
charged as the highest priority.
This is normally the drinking water cylinder. The cylinders can only be clearly identified via the cylinder sensors (cylinder 1 = Sp 2; cylinder 2 = SP 3).
You can only change this setting at the installer level.
The cylinder that has been assigned the highest priority
will always be charged if the collector temperature is
greater than the sum of the actual temperature in the
cylinder and the activation difference specified. The
heating of 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 deactivation difference.
The second cylinder can only be heated when the first
cylinder is not being heated. The charging of the second
cylinder is interrupted for at least 5 minutes every
15 minutes to check whether the cylinder can be
charged with the highest priority. The same activation
and deactivation conditions apply here as well.
4.12 Solar circuit protection function
If the solar heat exceeds the current heat demand
(e.g. all cylinders fully charged), the temperature may
occur in the collector field may increase rapidly.
If the safety temperature at the collector sensor is exceeded, the collector pump is switched off to protect
the solar circuit (solar pump, valves, etc.) from overheating, or restarting is prevented if a solar reheating
requirement exists. The solar pump is switched back on
once the system has cooled down. This function is executed independently for each collector field.
4.13 Solar pump kick (tube collector function)
Depending on the design of the tube collectors, the
measured value obtained for the purposes of temperature recording may be subject to a time delay. This can
be reduced via the tube collector function.
Measured value of collector temperature with active
tube collector function:
The solar pump is switched on for 15 s (solar pump kick)
once the temperature at the collector sensor has risen
by 2 °C. The heated solar fluid is thereby transported
more quickly to the measuring point.
If the temperature difference between the collector and
cylinder temperature is at least 10 °C) the solar pump
runs for as long as is necessary to heat the cylinder up
(differential control). If two solar circuits are connected,
the tube collector function is activated for both solar
circuits.
The function is implemented separately in each case for
all collector fields.
4.11 Frost protection function
The frost protection function is relevant to Spain only
due to statutory regulations and is deactivated in the
as-delivered condition (standard setting: OFF).
Note
h
This function should not be activated to prevent undesired cooling of the cylinder.
