• Switch on and off
Distinction can be made between two types of switch on/off commands:
- global command
- local command for one zone
The global command switches off all equipment and may be performed in 3 ways:
- manually using the
button,
- from an external contact,
- from the Modbus (solely for the SLAVE controller with Modbus)
The local command switches off only one zone and may be performed in two ways:
- manually by accessing parameters
OC1
for zone 1,
OC2
for zone 2,
OC3
for zone 3,
OC4
for zone 4
- automatically from the clock, programming the time slots of the 4 zones (if
I78
=1)
Global commands:
Switching on/off from an external contact has maximum priority. If the external contact is in OFF position, the equip-
ment cannot be manually restarted or by Modbus or by time slots.

switched on or off by pressing button
(until

is displayed) or through Modbus (through the
ON_OFF_VIA_
MODBUS
register (see

).
The manual global switch on/off has the same priority as the one through Modbus. This means that if the appliance is
globally off in manual mode, it can be restarted through Modbus or viceversa.
