SET: push to display the setpoint temperature.
The setpoint can be changed within
5 seconds with the “UP” or “DOWN” button.
The control will automatically switch
back to normal operating mode within 5
seconds; the last entered setpoint will stay
in memory.
UP: used to increase the setpoint value, as
well as the parameter when in programming.
When held down for a few seconds,
the change rate accelerates.
DOWN: used to decrease the setpoint value,
as well as the parameter when in programming.
When held down for a few
seconds, the change rate accelerates.
Led “ON”: status light of the output.
PARAMETER PROGRAMMING
Programming is easily accessed by holding
the “SET” button down for more than 4
seconds.
The first parameter is displayed; other parameters
are accessed with the “UP” and
“DOWN” button. With the “SET” button,
the actual setting of each parameter is displayed.
To change a parameter setting,
push the “SET” plus the “UP” or “DOWN”.

d1: setpoint differential.
The switching differential (hysteresis) can
be set with positive value (make on rise) or
with negative value (make on fall). See parameter
“HC1”.
LS1: Lower Set.
This is the lower limit below which the user
cannot change the setpoint; normally set
at the lowest value recommended for the
sensor.
HS1: Higher Set.
Similar to “LS1”, however setting an upper
limit for the setpoint.
