The control unit operates in three operating modes:
"Operating" mode: Depending on the configuration,
■
settings and external parameters, the appliance
operates according to the control algorithm in the
opening phase of the mixing valve, so that a set
inlet temperature is reached in the circuit.
"Standby" mode: Operating mode used outside the
■
heating period. The mixing valve is closed and the
pump is switched off. Once a day, according to the
periods set by the user (protection period for the
pump), the pump is switched on and the mixing
valve is opened and closed to prevent blockage
in the appliance during a long standby period.
"Configuration" mode: Operating mode for setting
■
the module's configuration parameters.
Operating modes are set via the master appliance
(boiler). Manual settings made from the control panel
are changed by the system to the currently required
settings after 30 seconds of keyboard inactivity. The
operating mode is selected using the buttons on the
control panel, as shown in Figure 6.
