Resolution: 1 °F with unit of measure in Fahrenheit, 1 ° C with unit of measure in

Celsius.

Display: one red LED 3-digit displays 13.2 mm (0.51 in) high, one red LED 2-digit

display 13.2 mm (0.51 in) high, two LED bars (10 red LED), output status indicators,

indicators of the unit of measure of the temperature showed by the instrument.

Outputs: 3 relays: one 8 A @ 250 Vac relay for top heating group control (NO),

one 8 A @ 250 Vac relay for floor heating group control (NO), one 8 A @ 250 Vac relay

for chamber light control (NO); the maximum current allowed on terminal 26 is 10 A.

AA1 -99 999 °C/°F

(6)

0 first temperature alarm threshold (it is important if AA4 ≠ 1); look at AA4 as well

AA3 0 999 min 0 first temperature alarm exclusion time since you turn the instrument ON (it is important if

AA4 ≠ 1)

AA4 1 7 --- 1 kind of temperature alarm (1 = it will never be activated, 2 = absolute lower temperature

alarm, 3 = absolute upper temperature alarm, 4 = lower temperature alarm relative to the

working setpoint, 5 = upper temperature alarm relative to the working setpoint,

6 = lower temperature alarm relative to the working setpoint with automatic calculation and

enabling, 7 = upper temperature alarm relative to the working setpoint with automatic

calculation and enabling)
