DIFF differential
type and Carel supervisor address integer var. 7
Modbus address read/write register 107
resolution and unit of measure 1%
range 0 to 100
default 10
Parameter used to set the value of the control differential. Expressed as a % of the full scale of the probes used. Only used if configuration by parameter rather than by
trimmer is enabled.
The effective value of the differential is internally limited to the value:
- 100- effective set point in Direct mode;
- effective set point in Reverse mode.
so as to guarantee that the maximum output is reached.
MIN minimum output
type and Carel supervisor address integer var. 8
Modbus address read/write register 108
resolution and unit of measure 1%
range 0 to MAX
default 30
Parameter used to set the minimum output value of the controller.
Expressed as a % of the mains voltage.
Only used if: configuration by parameter rather than by trimmer is enabled.
MAX maximum
output
type and Carel supervisor address integer var. 9
Modbus address read/write register 109
resolution and unit of measure 1%
range MIN to 100
default 100
Parameter used to set the maximum output value of the controller.
Expressed as a % of the mains voltage.
Only used if: configuration by parameter rather than by trimmer is enabled
MODE slave
mode
type and Carel supervisor address integer var. 10
Modbus address read/write register 110
resolution and unit of measure 1
range 0 to 3
default 0
Parameter used to enable slave mode.
MODE=0 slave mode disabled; normal operation of the controller;
MODE=1 slave mode 1 enabled;
MODE=2 slave mode 2 enabled;
MODE=3 slave mode 3 enabled;
For a detailed description of operation in the various modes, see the paragraph “Function slave mode”.
ALMO output in alarm status
type and Carel supervisor address integer var. 11
Modbus address read/write register 111
resolution and unit of measure 1
range 0 to 2
default 2
Parameter used to set the value of the output in the event of faulty probe alarms or external alarm.
ALMO=0 output 0%;
ALMO=1 output 50%;
ALMO=2 output 100%.
COFH Cut-off hysteresis
type and Carel supervisor address integer var. 12
Modbus address read/write register 112
resolution and unit of measure 1%
range 2 to 100
default 2
Parameter used to set the amplitude of the activation hysteresis for the Cut-off function.
Warning: the value of hysteresis must be:
< effective set point in Direct mode
< 100-effective set point in Reverse mode
otherwise the conditions cannot exist to set the output to zero.
