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.
