TLZ11 Digital thermostat for Heating or Cooling
AsconHeating or Cooling applications and ON/OFF control mode
TLZ 11 is a digital microprocessor based thermocontroller for Heating or Cooling applications and ON/OFF control mode. The instrument has up to 2 relay outputs, one input for PTC or NTC temperature probes and a digital input, that can be configured. The 2 outputs can be used for controlling the temperature control device (OUT) and an alarm (AL). The instrument is equipped with 4 programme keys, a 4-digit display and 2 LED signals, in addition to an internal buzzer that is the sound system for alarms. Other important characteristics of the instrument are: programme parameters protection using personalised password, switching on and off (stand-by) of the instrument using the “U” front key, configuration of parameters via the KEY 01 device and the possibility of power supply in the range 100 ... 240 VAC.
