The LCD visual display unit is provided with backlighting which is active for 5 secs
whenever a key is pressed.
In SET or PROG mode the backlighting remains active during parameter setting and pro-
gramming. It is deactivated on exit from these modes.
The programmer can be connected to the GW90821 GSM remote control unit using a serial
connection. SMS commands (e.g. from a cellular telephone) can be used to:
- Set the operating mode (MAN/AUTO/OFF)
- Set the output status (ON/OFF)
- Request the current status
Each command SMS sent to the device will be answered by a corresponding SMS in con-
firmation (with non-configurable predefined text); the status request message provides a
reply including the following information:
- current operating mode (OFF/AUTO/MAN)
- output status (ON/OFF)
Whenever the output status or operating mode are modified from the remote control unit,
the
symbol is displayed on the VDU.
The symbol also appears for the current contact status request.
The symbol remains displayed on the VDU until a key is pressed.
