1 V: 10 °C
Output Temp :
At this point, the target temperature can be set for 1 V (Boiler off = 0V).
10 V: 100 °C
Output Temp :
At this point, the target temperature can be set for 10 V.
Pump Type
standard/ 0-‐10v/ pwm
The type of pump used is set here.
For a PWM pump 1 kHz = 10V
Pump Speed
min: 100 %
Here the minimum speed of the pump can be set. The speed of the boiler or
store charge pump is controlled, so that the desired temperature is reached at
the boiler. The speed of the boiler or store charge pump is always set at 100%
when the boiler is operating in a modulating capacity.
Note
If the boiler is set for modulating control or a temperature target – no speed
control of the boiler pump or store charge pump can occur!
Minimum Duration:
Boiler: 0..60 min.
Here the minimum duration of the boiler operation can be set, although the
maximum allowable boiler temperature will still activate the boiler safety shut-
off
Overrun Time:
Boiler Pump 0..20 min
Here the overrun time of the boiler pump can be set.
Overrun Time:
Store Pump: 0..20 min
Here the overrun time of the Store Charge Pump is set.
Note
For the control of the boiler, the rules of the boiler manufacturer must be
observed.

Solid Fuel Boiler Pump
The ‘Solid Fuel Boiler’ function can be used to provide the on/off control of the
solid fuel boiler pump. A temperature differential and minimum temperature
requirements are set, from which both conditions must be met before the pump
is started.
Solid Fuel Boiler:
Temp: min: 30..80 °C
When the solid fuel boiler sesnors reaches the minimum temperature, the ‘Solid
Fuel Boiler’ function is activated. The solid feul boiler pump runs until the
minimum temperature is exceeded by 2 K (hysteresis set at factory).
