Time schedules operate independently of the basic regulation mode. If used inappropriately,
time schedules may worsen the energy efficiency of your facility. Setting up time schedules
depends entirely on your creativity and provides a wide range of different combinations. Only
advanced users should use time schedules and only after they have been thoroughly familiarized
with the applicable functionalities of this device!
Description of a time schedule option:
Time schedule mode:
a)
Not used – time schedule is not active.
b)
Restricted – the output will be restricted during the interval specified in the "From - To" field. If
the "From" time is larger than the "To" time, the restrictions or limitations are valid from the
"From" time to midnight and on the next following day from midnight to the "To" time.
Restriction applies to all activities of this output and has the highest priority.
During the time
interval neither basic regulation - based on the surplus energy - nor the CombiWATT mode will
work. Neither any other time schedule set to enforced mode will work. Output restriction does
not prevent outputs with lower priorities from working regularly.
c)
Enforced - the output will be enforced/switched-on during the time specified in the "From – To"
interval. If the "From" time is larger than the "To" time, the enforcement is valid from the "From"
time to midnight and on the next following day from midnight to the "To" time.
Enforcement has
the second highest priority
and it may be disabled only with another time schedule set to the
restricted mode at the same time. During the preset time interval the output enforcement
deactivates the basic regulation mode based on surplus energy (only if the Power field is set to
100%). However, it does not affect conditions for the activation of CombiWATT mode, which then
can run simultaneously with the enforcement mode. Output enforcement does not prevent
outputs with lower priorities from working regularly.
From – time when time schedule begins
To – time when time schedule ends
Power – (since firmware version 1.7) it can be configured for proportional outputs (if the function is
proportional or PWM) for the Enforced mode. This field can be used here to enforce the output power
as a percentage of the connected power. Thus, the output can be switched proportionally even when
switched by the time schedule. If the power is set lower than 100% then such enforcement does not
deactivate the basic mode of regulation according to surplus energy. For example, if the output is
enforced to 50%, and the surplus is available for the switching on 75%, the output will be switched to
75% of its nominal power. For the Restricted mode, this value is not used.
Always keep the value equal to 100% in cases where the output is set to the proportional
function, causing an increased flicker (fast changes in mains voltage or rapid flashing of light
bulbs and fluorescent lamps). The output will always be permanently switched on when fully
excited. See the flicker recommendation in the Frequently Asked Questions section of the
manufacturer's website.
M to S – (since firmware version 1.7) shortcuts for weekdays. The time schedule will be active only on
checked days.
LT – If you mark this field, the time schedule additionally requires the existence of the low tariff signal
to become active. This function differs based on the time schedule mode, and it is primarily based on
the fact that electric power in low tariff is cheaper than electric power in regular (peak) tariff:
a)
Restricted mode – the output is restricted only if low tariff is not active.
b)
Enforced mode – the output is enforced only if low tariff is active.
