Display: two 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, output status indicators, indicators of the unit of meas-
ure of the temperature showed by the instrument.
Outputs: 6 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 10 A @ 250 Vac relay
for steam generator control (NO), one 8 A @ 250 Vac relay for steam injection control
(NO), one 8 A @ 250 Vac relay for extractor control (NO), one 8 A @ 250 Vac relay for
chamber light control (NO); the maximum current allowed on terminal 21 and 26 is
10 A.
