Series TSXT Digital Temperature Switch
Specifications - Installation and Operating Instructions
Bulletin T-TSXT
The
Series TSXT Digital Temperature Switch
is designed with many refrigeration
applications in mind. It accepts up to 3 temperature inputs, of either PTC or NTC
temperature probe types and can control the compressor, defrost, fan, alarm, and
light in a refrigeration system. These switches allow master/slave configuration to
synchronize the defrost cycle between different units. The Series TSXT programming
performed by the front keypad, the TS2-K programming key, or by RS485 module
communication. Standard features include capacitive buttons, real time clock, HACCP
alarm logging, temperature alarms, and password protected parameter settings.
INSTALLATION
Note:
Unit must be mounted away from vibration, impacts, water, and corrosive gases.
• Cut hole in panel 2.80 x 1.14 inches (71 x 29 mm).
• Use the included gasket, or apply silicone around the perimeter of the hole to prevent
leakage.
• Insert the unit into the hole in panel.
• Slide removable fitting clips onto unit from back until secure to panel.
• Wire the unit per the wiring diagram on the product label or by figures below. Avoid
installing temperature probe and digital input wiring in the proximity of power cables.
