Extended economy mode
The heating circuit pump is switched off
and the flow temperature set value is set
to 0 °C, if one of the following criteria is
met:
■ The outside temperature exceeds the
value selected via coding address
"A6".
■ The mixer has been closed for 20 min.
(mixer economy function, coding
address "A7").
Frost protection
With outside temperatures below +1 ºC,
a minimum flow temperature of 10 ºC is
safeguarded. For changes see coding
address "A3", variable frost limit.
Upper control limit
Electronic maximum temperature limit
Setting range: 1 to 127 ºC,
changes via coding address "C6".
Note
The maximum temperature limit is no
substitute for the underfloor heating sys-
tem temperature limiter.
Temperature limiter for underfloor heat-
ing:
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 temperature limit
Setting range: 1 to 127 ºC
Change via coding address "C5".
Only enabled during operation with
standard room temperature.
DHW temperature control
Brief description
■ The cylinder temperature controller
regulates with a constant temperature.
This is achieved by starting and stop-
ping the circulation pump for cylinder
heating.
■ When the DHW cylinder is being
heated, a set boiler water temperature
is defaulted that lies 15 K above the set
DHW temperature (adjustable via cod-
ing address "60").
Functions
Time program
An automatic program or an individual
time program may be selected for DHW
heating and the control of the DHW cir-
culation pump.
To control DHW heating, up to four time
phases per day can be set in the individ-
ual time program via the time switch.
