IMPORTANT
Before wiring communication network, it is necessary to confi gure each unit independently and assign it a different
channel number.
6.6. TIMER RTC
TIMER RTC function is available in all units but its confi guration is only through Modbus parameterization (see Modbus
map holding registers 40083 to 40100 and 40152 to 40319). This functionality allows:
• Schedule each hour of the week independently
• Schedule holidays period
IMPORTANT
TIMER RTC function requires date and time setting before programming. This action must be carried out by means
of Modbus parameterization and holding registers 40095 to 40100. The battery (location BT1) will allow the equip-
ment to keep on date and time when it is not powered.
