Honeywell T775A2009 manual Electronic Standalone Controllers, Standard Models, T775 Special Models

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.
