The timer determines whether day correction or night
correction (set back ) is used for changing the set flow
temperature. 21 different time frames (3 for each day)
can be set for night correction of the heating circuit.
If one of the time frames is set to ‘active’, night correc-
tion will be active.
If none of them is active, the set flow temperature will
be adapted with day correction. The timers are pre-
allocated such that every day from 10:00 pm to 5:00
am (the following day) night set back is active.
The mode determines the operation mode of the timer:
Night/ day time frame for night correction
off / day time frame for heating circuit off
without: timer deactivated
Timer:
Arrangement/Heat. circuit/hc/timer/Mode
selection: “Night / Day“, “Off / Day“, “Without“
factory setting: “Night / Day“
Arrangement/Heat. circuit/hc/timer/t1(...21)-on
adjustment range: 00: 00 ... 00:00
factory setting: 22:00 (t1...t7-on)
Arrangement/Heat. circuit/hc/timer/t1(...21)-off
adjustment range: 00: 00 ... 00:00
factory setting: 05:00 (t1 ... t7-off)
Example: The night correction runs from Monday to Tuesday
from 22:00 to 6:00 and Tuesday from 15:00 to 18:00, when t1-
on is set to mon 22:00, t1-off to tue,6:00 and t2-on to tue,15:00
and t2-off to tue,18:00.
Adjustment channel for allocating the sensor in flow.
The default is sensor 6 – this can be reallocated if nee-
ded. A sensor which is already in use can be allocated
without influencing its original function in the system.
Flow sensor:
Arrangement/Heat. circuit/hc/Expert/Sen.flow
adjustment range: 1 ... 10
factory setting: 6
Adjustment channel for summer operation. If the out-
door temperature exceeds the adjusted value, the he-
ating circuit will be switched off. The hysteresis is 1,0 K.
Summer:
Arrangement/Heat. circuit/hc/summer
adjustment range: 0 ... 40 °C
factory setting:: 20 °C
The mixer function controls the mixing valve position
according to the difference between the actual flow
temperature and the set flow temperature. The valve is
opened or closed in pulses depending on this deviation.
The parameter „mixer“ allows the pulse operating time
to be matched to suit the valve operating time.
Mixer:
Arrangement/Heat. circuit/hc/mixer
adjustment range: 1 ... 20 s
factory setting: 2 s
