If the output is “not used” there is the possibility to use the
output as a booster pump of the main pump P1 with System 1.
This function is useful when utilizing a “drain back system” to
enable the primary pump P1 to initiate the circulation of the
heat transfer fluid.
In this instance pump P2 is normally installed in series with the
main pump P1.
- You could choose the duration for the running time of P2 with
(+) or (-). (Adjustable 1 to 10 minutes)
Booster function explanation:
Exemple:
2.4.3 Pump P3
P3 is a supplementary output which can be used for an
additional extra function and is generally used in combination
with the solar system or totally independent. There will be a
choice between the different functions depending upon the
selected system configuration selected.
2.4.3.1 Thermostat Heating Function
With an additional sensor (T3) this function is used for
secondary heat source pump (P3) control.
Suggestions:
- Pump controls for Fuel or Gas burner…
- Immersion Electrical Heater inside the solar tank.
Important: In this instance an external power relay must be
connected for the switching of the output load!
Example:
All adjustable settings available for this function are accessible
in the Settings menu; see section “Settings” chapter 2 for a
further explanation of the functions.
2.4.3.2 Thermostat Cooling Function
With an additional sensor (T3) this function is used for
cooling of the solar tank with an external heat sink
Suggestions:
Charging a swimming pool.
Example:
All adjustable settings available for this function are accessible
in the Settings menu; see section “Settings” chapter 2 for a
further explanation of the functions.
2.4.3.3 Diffcontrol Function
With additional sensors (Tcold=T3, Twarm=T4) this function
is used for secondary heat source pump control or charging
a tank.
The loading of the Tcold=T3 is activated if the temperature
difference “dt” between the Twarm=T4 and the Tcold=T3 is
sufficient.
