Function description
Heating circuit control
(cont.)
Upper control limit
Electronic maximum limit
Setting range: 1 to 127
º
C
Changes via coding address C6.
Note
The maximum limit is no
replacement for the underfloor
heating system temperature limiter.
Temperature limiter for underfloor
heating:
The temperature limiter switches the
heating circuit pump OFF, if the set
value has been exceeded. In such
cases, the flow temperature reduces
only slowly, i.e. it may be several
hours before the system restarts
again automatically.
Lower control range limit
Electronic minimum limit
Setting range: 1 to 127
º
C
Changes via coding address C5.
Control sequence
Mixer circuit
The mixer motor will not be selected
within the
Neutral zone
(±1 K).
Flow temperature falls
(set value −1 K)
The mixer motor receives the signal
Mixer open
.
The signal duration lengthens with
an increasing control differential.
The duration of pauses reduces with
an increasing control differential.
Flow temperature rises
(set value +1 K)
The mixer motor receives the signal
Mixer close
.
The signal duration lengthens with
an increasing control differential.
The duration of pauses reduces with
an increasing control differential.
