The user can see the temperatures of the storage tank, the counterflow pump, the heat source and
the upper (Tbo 1), lower (Tbo 2) and storage tank output (Ts out).
In order to enter the system status and the various system settings, as shown in the following figures
(14, 15), press the
Λ
key.

Specifically, while in the Setup Ref screen (fig. 16), by keeping the set key pressed, the user can set :
(1) the SpNor , i.e. the desired DHW outlet temperature under normal operating conditions (e.g., 48°C).
(2) the Sp Eco , i.e. the DHW outlet temperature in economy mode (usually adjusted lower than the
Sp norm, e.g., 42°C). It is activated only with the
Sch/er S/p
(see below), for higher savings at night.
(3) the Diff determining the counterflow Δ t, i.e. the differential restart temperature. For example, if Sp
norm = 48
o
C and Diff = 1, the counterflow begins at 47
o
C and stops at 48
o
C.
(4) the
Reflu
, i.e. the way to activate/deactivate the counterflow function.
- The counterflow is deactivated in the “Reflux off” option.
- Apart from the Sp norm (eco) and the Diff ( Δ t), in the “Reflux on” option, the counterflow also
“monitors” the tank’s temperature. This is mostly for domestic use. E.g., we set the Sp norm at 48
o
C
and start heating the tank at 30
o
C. The counterflow will begin when the tank reaches 46
o
C, and ceases
at 48
o
C. Between 46
o
C and 48
o
C, the counterflow will function according to the Δ t that we have set. If
the tank’s temperature falls below 44
o
C, the counterflow will stop until the temperature reaches 46
o
C
again. In this way, we achieve higher temperatures in the tank. Caution: for the Reflux option to operate
property, the Tbo1 (Aux) sensor must be installed.
- In the “Reflux max” option, the counterflow does not “monitor” the tank’s temperature, only the Sp
norm (or Sp eco) and Diff (
Δ t). This is mostly for hotel use so that the system may always provide the
hot water fast, from the top of the tank. The Tbo1 (Aux) sensor is not necessary for this option.
Following the above settings, the user must not press any key for about 3 seconds.
