Honeywell T775A2009 manual Proportional Temperature controllers, T915, T7079

Proportional Temperature controllers

T915

For ducts, tanks, boilers, pipes and other heat exchangers.

•Provide proportioning control of three-wire, low-voltage valve or damper motors.

•Used to regulate temperatures of either air or liquids.

•All models ambient compensated.

•Ambient temperature compensation provides good temperature control.

•Temperature setting scale markings in both Fahrenheit and Celsius.

•Steel case has a clear plastic cover to make setting readily visible.

•Surface mount using two screws through back of case.

Electronic remote temperature controllers

T7079

Capable of providing on-off temperature control for ducts, tanks, heating and refrigeration units, greenhouses, animal confinement buildings and other applications where electronic accuracy in addition to remote sensing is desired.

•Choose from 1 or 2 SPDT relay models.

•Two stage models can be configured as 2 heat/2 cool, or 1 heat/1 cool.

•Switch selection of heat or cool mode.

•Temperature sensing up to 400 feet.

•Does not require field calibration.

•10K NTC temperature sensor.

•Wide setpoint temperature range.

•LED annunciation for both power on and relay state.

•Dual setpoint scale (˚F and ˚C).

•Models offered with built in isolation transformer for 24 Vac input.

•Dual-stage output models can be configured as 2 heat/2 cool, or 1 heat/1 cool.
