C.H.
With this function, you can set the temperature that will activate the central
heating pump and the hot consumption water pump (the temperature is
measured on the boiler). Below the setpoint temperature, the pumps are
disabled; above the setpoint temperature, the pumps are enabled but their
operation is based on the settings, i.e. the pumps are enabled alternately (see
the pump priority function or fixed central heating pump)
II.j) Central Heating Hysteresis
22
o
c
C.H.
With this function, you can set the hysteresis of the setpoint temperature.
This is a difference between the temperature of entering into the sustain
cycle and the temperature of returning to the duty cycle (e.g.: when the
setpoint temperature is set to 60°C, and the hysteresis is set to 3°C, entering
into the sustain cycle will be effected after the temperature reaches 60°C,
whereas return to the duty cycle will be effected after the temperature drops
to 57°C).
