R1 (R2) SET VALUE: Sets the reference value at which the relay R1 (R2) is

activated. This parameter has no effect if NORMAL (previous parameter) is
selected as SETPOINT TYPE.
R1 (R2) HISTERESYS: Sets, in percentage, the hysteresis of the relay

R1 (R2) MASK TIME: sets the masked time (in hh:mm:ss), measured from start,

within which the SETPOINT R1 (R2) is not driven even if the threshold value has
been reached. This parameter is not available if SETPOINT TYPE is set to
NORMAL
R1 (R2) OUTPUT LOGIC: Selects the control logic of the SETPOINT output.
