The TSS2
is an electronic temperature controller designed for ON/OFF
control or Neutral Area Control. They can be provided with 1 or 2 probes
(both PTC range -58 to 302ºF) according to parameter P5 and it
provides with two output relays plus an alarm buzzer. The unit controls
cooling, heating or both, since its relays can be setup for direct or
reverse operation. The user is able to program 34 different parameters
including set points, hysteresis, configuration of alarms and probe
