CLOCK ENABLE WITH TIME SCHEDULE
If the W500 is RTC-provided or it is connected via LinkBus to a device with clock, it is possible to
define the Operating Mode according to a weekly schedule and a daily schedule. The clock enable
of each Control Loop is obtained by setting the parameter ABO = On. If the device with clock is
connected via LinkBus to other equipments without clock, the mode can be shared and all the
equipments will follow simultaneously the same time schedule.
Weekly schedul
e:
For each day of the week it is possible to define either a fixed mode
(On = Comfort, rid = Reduced,
OFF = Stop)
or a complete daily schedule (expressed by the Pr1 value), or only the first two (Pr2
value), or only the last two (Pr3 value) changeovers of the daily schedule.
Daily schedul
e:
It is possible to carry out up to 4 time changeovers defining, for each one, hour, minute and mode.
Unused changeovers must be filled in with the same values of the last valid changeover.
For the setting of both weekly and daily time schedules, see page 25.
OUTSIDE DIGITAL ENABLE
Two digital inputs are available: they can be used independently by the 4 Control Loops to override
the active operating mode. It is necessary to make a distinction between HMB model (with clock)
and H model (without clock).
In both models, if parameter Abo = OFF (enabling by clock disabled) the Loop is STOPPED; if
parameter Abo = ON it follows the time schedules in HMB model and it is always in Comfort mode
in H model.
At this point, if on a Control Loop the Outside enable is started with parameter AE1= ON and/or
parameter AE2 = ON:
In HMB model
the D.I. 1 and/or D.I.2 contacts enable the Loop outside the time schedules
In H model
nothing happens (the loop is always in COMFORT mode)
If parameter Abo = OFF and parameters AE1= ON and/or parameters AE2= ON, the D.I. 1 and/or
D.I. 2 contacts are open the Loop is STOPPED, if one or both of them are closed the Loop is in
COMFORT mode.
If the Loop is configured to operate in A3 or D3 mode (Heating/Cooling by S/W changeover) the
digital input 2 is only used for this purpose.
The enabling from contact (Loop starting override) has priority with respect to the other
changeovers (from clock or manual override with
Ovr
-
key).

FACTORY DATA LOAD
Through this function it is possible, if required, to reset all the factory settings and parameters.
This function is useful for example when the user has set different values and requires restoring
the initial conditions in a short time.
