∆T return storage
Temperature difference for the storage tank stratification via a zone valve. If the temperature in the primary return flow
exceeds the corresponding storage tank temperature by the temperature difference set here, the valve switches on to
stratify in the upper storage tank zone. If the temperature drops below this temperature, the valve is switched off again.
When no storage sensor is connected, a temperature of 25°C is assumed.
AL-heating
With this function, a relay switches a boiler to anti-legionella mode as needed. The relay switches on when an anti-le-
gionella heating starts. The relay switches off when the AL-heating was completed successfully or if the enable time for
the AL-heating is exceeded. Activate or deactivate function.
Error Messages
The relay is switched on if one or several of the set protective functions are activated. This function can be inverted so that
the relay is turned on (Duration on) and then turned off again if a protective function is activated.
Error message
Activate or deactivate function
The additional function error message activates the relay for certain events and only deactivates again when the informa-
tion message to each event was read.
Additional Pump
A second pump in the primary circuit is switched on to support the primary pump. When the measured flow rate exceeds
“flow rate on”, and if this conditions is met throughout the period “delay”, the relay is switched on. Activate or deactivate
function.
Flow on
Adjustable flow rate in l/h, at which the additional pump is switched on.
Flow off
Adjustable flow rate in l/h, at which the additional pump is switched off.
Delay
The additional pump is switched on with a delay of the time set here.
Primary Mixer
When this function is activated, water is mixed in the primary circuit by a mixer via the primary return. As a result, less
energy is drawn from the storage tank at high storage tank temperatures, depending on the flow rate, since energy is
mixed from the return flow.
Primary flow min.
Setpoint temperature at mixing valve at min. flow rate.
Primary flow max.
Setpoint temperature at mixing valve at max. flow rate.
Turn Time
Length of turn time.
Pause Factor
Adjustment of mixer pause time.
Increase
Influence of fast temperature rises.
Solar
This function adds a solar circuit which is controlled by the collector and storage temperature.
Switch solar function on or off.
Tmin Collector
Enable/start temperature at sensor X:
If this value on the specified sensor is exceeded and the other conditions are fulfilled, the controller will turn on the affili-
ated pump or the valve. If the temperature on the sensor falls 5 °C below this value, the pump or the valve will be turned
off again.
