ELECTRONIC STANDALONE CONTROLLERS
T775
Provide on/off, modulating, or reset control in applications where
electronic accuracy in addition to remote sensing is desired.
Standard Models
• Available with one, two or four SPDT relay output stages and/or modulating
outputs (0-10 Vdc, 2-10 Vdc, 4-20 mA and electronic Series 90 selectable).
All models have built-in time-clock scheduler for setback.
• Typical applications include
– On/off control of fans, motors and heaters
– Proportional or floating control of damper and valve actuators
– Outdoor reset of heating and cooling systems

FREEZE STATS
L480, L482
For limit or temperature control in refrigerated areas where remote mounting
of sensing element is required.
• Liquid-filled copper elements provide rapid sensing to control the
compressor system.
• Control temperature in a duct, tank, freezer or cooler.
• Controller element can be directly immersed in the controlled medium.
• Adjustable control setpoint.
• Ambient temperature compensation provides good temperature control.
