The TTLDC Series has been discontinued and has been replaced by the TLDC Series.
The TTLDC multi point duct average temperature thermostat incorporates several precision thermistor temperature sensors and provides a Form C relay output (NO/NC) with an adjustable setpoint. The sensor is encapsulated in a 7.94 mm (0.3125”) OD, soft copper probe and is available in various lengths (see ordering chart). All probes provide excellent heat transfer, fast response and resistance to moisture penetration. Two enclosure styles are available.
