II.k) Hot Consumption Water Hysteresis
With this function, you can set the hysteresis of the setpoint temperature on
the water heater. This is a difference between the setpoint temperature
(required by the water heater) and the actual temperature on the boiler (e.g.:
when the setpoint temperature is set to 55
o
C and the hysteresis is set to 5
o
C.
After reaching the setpoint temperature, i.e. 55°C, the hot consumption water
pump is activated, causing the central heating pump to be activated. The hot
consumption water pump will be activated again when the temperature drops
to 50°C).
II.l) Blow Force
With this function, you can control the fan speed. The adjustment range is 1-
10 (referred to as gears). The higher the gear the higher the speed with the
1st gear being the minimum and the 10th being the maximum speed of the
fan.
Fan speed can be adjusted with
PLUS
and
MINUS
. Initially, the fan runs
always at full speed so that it is possible to start the fan with the motor being
slightly dusty.
