•
in the 0 or OFF position the unit is always OFF;
•
in the
“MAN” position the unit is ON but the control is bound to the state of the
analog/digital inputs;
•
in the
“AUTO” position it is possible to initiate a hot water request control (see
circuit diagram). The unit is ON if the remote control is ON but the unit start is
bound to the state of the analog/digital inputs.
When the digital input is active, the word “ON” is displayed in the top left corner of the controller
display, otherwise the word “OFF” is displayed if the input is not active.
8.7.5. Digital Input
– “HW Request”
The controller switches the unit on and off according to the status of a dedicated digital input.
The status of the digital input must be controlled by an external control system (PLC, clock,
thermostat or similar). See next chapters for operating logic. When the digital input is active, a
full dot appears on the display under “HWr”.
When the "double probe" function is activated, the status of this digital input is ignored.
8.8. Switching On/Off From Supervision System (Remote Control)
When switch-on/off of the unit is activated from the supervisory system, the symbol of a
PC
appears next to ON-OFF on the built-in terminal.
