Overwrite timer function

The timer output can be overwritten for a settable time with a selectable status if required. Activation is
by a digital input (
Application: Exceptions from the normal timing operation, e.g. for manual or automatic presence
switch, party mode, etc.

MODBUS Slave

Addressing and configuration of the MODBUS Slave interface.
Via this interface the device can be networked with a master building control system, the device then
operates as a pure Slave and uses the MODBUS-RTU protocol.
The connection is made to the terminals "A (D+)", "B (D-)" of the MODBUS Slave interface (see
installation / RS-485 interfaces for MODBUS RTU).
Information
•
In the IO Setup the "COM function must be set" to "MODBUS Slave" so that this menu group is
displayed (factory setting).
•
MODBUS settings (baud rate, parity) are saved after a reset (see menu group "Start" -> "Reset" or
interrupt voltage supply).

Override Time
Settable time for overwriting the timer function
Setting range: 0...65535 min.
Factory setting: 120 min
In the "0 min." setting, the timer function is overwritten with the selected status until the
next timing change.
Override Status
Settable status when overwriting the timer function:
ON = function as for timer ON
OFF = function as for timer OFF (factory setting)
Fine adjustment of the real time clock is possible if required.
The greater the value, the slower the clock runs. If the value is increased by one point,
this corresponds to a slowing of the clock by approx. 2 to 3 s per month.
Setting range: 0 - 127
Factory setting: 60
Bus Address
The device address is factory set to the highest available MODBUS address: 247.
Setting range MODBUS Address: 1 - 247.
Addressing
Switch addressing to "ON" before setting "address".
