type and Carel supervisor address digital var. (read only) 24
Modbus address read coil 24
resolution and unit of measure 1
range 0/1
default --
Variable used to read the status of the probe B2 fault alarm.
PB2A=0
inactive
PB2A =1 active
The alarm is activated automatically if the value read by probe B2 is outside of the range of possible values, typically due to disconnection or short-circuit.
The alarm is only detected if probe B2 is enabled.
The alarm is not detected if slave mode is selected.

PB3A=0
inactive
PB3A =1 active
The alarm is activated automatically if the value read by probe B3 is outside of the range of possible values, typically due to disconnection or short-circuit. The alarm is

OKHZ
mains frequency reading status
type and Carel supervisor address digital var. (read only) 26
Modbus address read coil 26
resolution and unit of measure 1
range 0/1
default --
Variable used to read the status relating to the reading of the mains frequency.
OKHZ=0 reading in progress
OKHZ =1 reading completed
At the end of the reading, the variable STHZ signals the frequency, 50 or 60Hz.
STHZ mains
frequency
type and Carel supervisor address digital var. (read only) 27

resolution and unit of measure 1
range 0/1
default --
Variable used to read the mains frequency detected by the controller.
STHZ=0 50Hz
STHZ=1 60Hz
The value of the variable is only meaningful after the mains frequency has been read by the controller (see parameter OKHZ).

type and Carel supervisor address digital var. (read only) 28
Modbus address read coil 28
resolution and unit of measure 1
range 0/1
