Function description
The output control function is used to control loads (e.g.
EHS
immersion heater or
LST
output con
-
troller) according to the specifications of the
energy manager
function, or by means of forced op
-
eration.
When used with an
energy manager
function, output control is specified in this function's param
-
eters as an
involved function
. Up to 12 output controls can be managed by one energy manager.
For use without an
energy manager
function, the
forced operation
and
forced operation output
input variables are used. The output can then be specified manually or by any other control event.
With the
Participating CORA device
parameter,
Output control
makes it possible to control a de
-
vice using the
"CORA"
wireless system. Further information on this wireless system can be found
in the installation instructions for the corresponding devices.
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Minimum output
Upper and lower limits of the output to be consumed
Maximum output
Start differential
The consumer is not activated until the
minimum start dif
-
ferential
is reached.
The consumer is deactivated again when the output falls below
minimum output
.
Operation proceeds, taking account of the
minimum runtime, stop
delay
and
blocking time
parameters.
Forced operation
The consumer is enabled without taking account of the specifica
-
tions of the energy manager (digital value ON/OFF).
Forced operation output
Set output when
forced operation
is active.
• When used in conjunction with an energy manager, the set output comes from that function;
otherwise from the
forced operation output
input variable.
• Forced operation takes precedence over the specifications of the energy manager func
-
tion.
• The value of the
maximum output
input variable should not exceed the maximum output of
the consumer (e.g. 3 kW for an EHS immersion heater).
• All input variables related to power can be given values in the units
W
or
kW
. The unit is recog
-
nised automatically.
• If a non-regulated consumer is to be switched, the
minimum power
and
maximum power
must
be set to the same value. The start differential continues to have an effect with this setting.
• Percentage values can also be applied to the input variables
minimum power
and
forced oper
-
ation output
. These refer to the maximum power (100 % = maximum power).
