Remote Temperature Controllers
Quick Selection Guide
A Complete Selection For A Wide Range Of Applications
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

T775 Special Models
T775U — Universal model controls pressure, humidity, temperature
or any control medium that inputs 1097 ohms PTC, 0-10 Vdc or 4-20 mA. CO2 sensors are compatible but reading displayed in percent, not ppm.
T775P — Special boiler model with features like WWSD, Alarming
and control of up to 12 stages from a single setpoint using optional 4-relay expansion modules T775S.
T775L — Special sequencing module allows configuration of up to 12 relay outputs with one or two setpoints in any number and combination desired. Do 3 heat/7 cool, 6 heat/2 cool, 4 heat/2 heat — whatever you desire.

T4031, T6031 |
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.
Used to limit or control temperature in air conditioning systems or refrigerated enclosures.
•Applications include freezer cabinets, display cases, beverage coolers, milk cooling tanks and cooling coils.
•Can act as a frost alarm operator in storehouses or orchards where frost would damage crops or equipment.
