tions for the heating expert) can be carried out.
The following special functions are possible:
– Manual operation (see chap. 3.5.1).
– Displaying messages (see chapter 7)
– Reset to factory settings (see chap. 3.6.12)
Detailed explanations of these functions can be found in chap. 6.11.

3.5.1 Manual operation
Manual operation is used to manually control the ROTEX HPSU
monobloc compact to a specific feed temperature. Manual oper-
ation should only be used for diagnostic purposes.
With hydraulically controlled priority operation for hot water prep-
aration, it must be ensured that the target feed temperature set in
manual mode is sufficient to achieve the stored target hot water
temperature (parameter [T-DHW Setpoint 1]).
●
Push the Exit button for at least 5 s.
Menu
"Special Level"
is displayed.
●
Use the rotary button to select the
"Manual Operation"
program.
●
Confirm the selection with a brief push of the rotary button.
"Manual Operation"
is active.
●
Use the rotary button to set the target feed temperature.
During active manual mode, the storage tank temperature
is permanently regulated to the first target hot water tem-
perature parameter value ([T-DHW Setpoint 1]).
The key lock (if it was activated prior to the start of this
function) is reactivated within 2 s to prevent undesired
cancellation of the function through operation of the
RoCon mb controller.
●
Cancellation and jump back by:
– pressing the Exit key again or
– touching the rotary button or
– selecting another menu using the rotary switch.
If manual operation is ended, the RoCon mb control unit
automatically switches to "Standby" operating mode.
3.5.2 3-way switching valves reference travel
The positions of the two 3-way switch valves 3UVB1 and 3UV
DHW in the ROTEX HPSU monobloc compact are controlled
continuously between their two basic settings for optimised
energy utilisation (e.g. heating support function).
To ensure this function, the two 3-way switch valves are always
moved automatically to their basic position (bypass - path AB-A
open) at 11:00 hours.
This function can take up to 5 minutes. It is programmed as
standard and cannot be changed.
The calling-up of the special functions does not depend
on the rotary switch setting.
Do
not confirm
this setting
with the rotary button
,
as the program is otherwise ended.
