BLUEHELIX TOP RRT K 50
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. If the room thermostat is not installed, the boiler
will keep the system at the set system delivery setpoint temperature.
Room temperature adjustment (with optional remote timer control)
Using the remote timer control, set the required temperature in the rooms. The boiler will adjust the system water ac-
cording to the required room temperature. For operation with remote timer control, please refer to the relevant instruc-
tion manual.
Tank exclusion (ECO)
Hot water tank temperature maintaining/heating can be excluded by the user. If excluded, domestic hot water will not
be delivered.
The device can be deactivated by the user (ECO mode) by pressing the winter/summer/off button (detail 7 - fig. 1) for
5 seconds. In ECO mode the display activates the ECO symbol (detail 12 - fig. 1). To activate the COMFORT mode,
press the winter/summer/off button again (detail 7 - fig. 1) for 5 seconds.
Sliding Temperature
When the external probe (optional) is installed, the boiler adjustment system works with "Sliding Temperature". In this
mode, the heating system temperature is regulated according to weather conditions, to ensure high comfort and energy
efficiency throughout the year. In particular, as the outside temperature increases the system delivery temperature de-
creases according to a specific "compensation curve".
With the Sliding Temperature adjustment, the temperature set with the heating buttons (details 3 and 4 - fig. 1) becomes
the maximum system delivery temperature. It is advisable to set a maximum value to allow system adjustment throug-
hout its useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. However, the user can make any further
adjustments necessary to optimize comfort levels.
Compensation curve and curve offset
Press the reset button (detail 6 - fig. 1) for 5 seconds to access the "Sliding temperature" menu; the display shows "CU"
flashing.
Use the DHW buttons (detail 1 - fig. 1) to adjust the desired curve from 1 to 10 according to the characteristic (fig. 14).
By setting the curve to 0, the sliding temperature adjustment is disabled.
Press the heating buttons (detail 3 - fig. 1) to access parallel curve offset; the display shows "OF" flashing. Use the DHW
buttons (detail 1 - fig. 1) to adjust parallel curve offset according to the characteristic (fig. 15).
Press the heating buttons (detail 3 - fig. 1) to access the menu "shutdown for external temperature"; the display shows
"SH"flashing. Use the DHW buttons (detail 1 - fig. 1) to adjust the shutdown external temperature. If set to 0 the function
is disabled; the range varies from 1 to 40°C. Lighting occurs when the external probe temperature is 2°C lower than the
set temperature.
Press the reset button (detail 6 - fig. 1) again for 5 seconds to exit the "Sliding Temperature" menu.
