Current thermal performance: The corresponding
maximum value is displayed when "SET" is
pressed.
Fig. 19: Current thermal performance, maximum
value
Daily heat content: When "SET" is pressed, the
total heat content and the daily heat content are
displayed alternately.
Fig. 20: Display of total heat content and daily heat
content
In cascade operation, each controller displays
its "own" calculated heat content.

Circulation
Switches a circulation pump that is controlled by
temperature, clock and/or flow on and off. The
three control modes can be combined in any way.
Temperature control: If the temperature on the
circulation return falls below the T
on
value, the cir-
culation pump is switched on until the temperature
reaches the T
off
value. The temperature control is
time-limited if the clock control is activated.
Clock control: If the current time is within one of 3
time windows that can be set, the circulation pump
is:
n Permanently switched on if the temperature
control is deactivated ("oFF")
n Controlled by temperature if the temperature
control is activated ("on")
Flow control: Flowing for a short time (<5s)
switches the circulation pump on for the duration of
activation. After the duration of activation expires,
the circulation pump remains switched off at least
for the duration of the waiting time. The flow con-
trol works independent of the clock control.

Distribution valve in return flow
Switches the distribution valve in the return flow

R2.
No further settings are required.
The function can only be activated or deactivated.
R2 on if TKW ≥ 28 °C
R2 off if TKW ≤ 23 °C
