Unit Function
Centralized Control and Week Timer
Functions: The centralized control- ler
and the weekly timer are integra- ted in
the same wire controller. The system
has both the centralized control
and the week timing functions. Up to
16 sets of units can be control- led
simultaneously by the centralized
controller (weekly timer). The weekly
timer has the function of invalidating
lower unit. The weekly timing function
is able to realized four timing ON/OFF
periods for any unit every day, so as to
achieve fully automatic operation.
This WEEKLY TIMER adopts 485
mode to communicate with manual
control of every duct type unit, and it can
control up to 16 units. Adopting 2-core
twisted-pair wire, the longest
communication distance of this TIMER
is 1200m. After connected to power, the
WEEKLY TIMER can display all
connected units (sequence of unit is
determined by code switch of manual
control of every duct type unit). On and
off of every duct type unit can be done
through the Timer On / Off of this
WEEKLY TIMER, and the button shield
operation of manual control can be done
through shield setting on WEEKLY
TIMER. Mode selection and temperature
adjustment and other operations are done
through the manual control at every unit.
Arrangement
Note:
1. For upper unit checks 16 lower units consecutively, there will be no more than 16 seconds delay
when setting works till unit responds.
2. Please let us know your requirement before your placing the order, for this WEEKLY TIMER will
only be prepared when customer orders (communication joint with WEEKLY TIMER on manual
control had been prepared).
1. Press or
Group Control (1~16), or control single unit by Single Control.
2. When selected a certain or several units by Single Control or Group Control, Timer setting and On/off
setting can be set. Timer setting can set 4 on/off times in a day in one week; and on/off setting can be
done by pressing on/off button.
