Operating Cycles SATK20 High Temperature
Heating cycle: ON/OFF regulation.
When the room thermostat requests the start of a heating
cycle, the valve is opened completely, allowing water to
circulate at the temperature supplied by the central heating
system (ON-OFF regulation).
The valve is closed on completion of the heating cycle.
The active heating cycle is signalled by the yellow CH LED
which comes on.
No value is shown on the display.
Optional functions
- to activate/deactivate the optional
functions the electric power supply must always be turned off.
Domestic water generation
Domestic water pre-heating function
The function is enabled by setting dip switch 5 to the ON
position.
During periods when the domestic water cycle is not used, if
the DHW probe detects a temperature 10˚C below the SET
value, the controller partially opens the domestic water
modulating valve for the time required (max. 5 mins) to bring
the temperature detected up to a value 5˚C below the set point
value.
The domestic water preheating function is signalled by the
flashing yellow DHW LED.
This function is less of a priority than any domestic water or
heating cycles.
Safety and alarms
Error codes associated with faults are signalled by the
illumination of the FAULT LED are also shown on the display
(see page 8).
