Honeywell Electronic HVAC Controllers
Honeywell T775 Electronic Standalone Controllers
The newly redesigned T775 "2000" series of electronic standalone controllers incorporates many new features to make it the most economic and flexible controller available. All T775’s can be powered with low or line voltage (24, 120 or 240 VAC).
- Easy-To-Use Graphical Interface
- Internal Time Clock Scheduler
- Up to Two Independent Modulating Outputs (Selectable: 4-20 mA, 0-10 Vdc, 2-10 Vdc and Series 90)
- NEMA 4X Enclosure Option
- Modulating High Or Low Limit Control
- Optional Configurable Integral and Derivative Times
- Reset Models With Simplified Setup
- Configurable Minimum Off Time
- Sensor Calibration
There are many remote temperature sensors that are compatible with the T775 Series 2000. The T775 accepts 1,097 Ohms PTC at 77°F.
Honeywell T775 Universal Model
The 775U Universal Model provides setup for configuring control of:
-Or any 0-10 Vdc or 4-20 mA input
The input range of this model is completely scaleable!
You select which units you are measuring and displaying (inches W.C., PSI, Pa, kPa, %RH, o F or o C or just generic %).
This is the first commercial controller with this capability. Previously, you had to use an Industrial Single Loop Controller at three times the cost to control any other application other than temperature or %RH.
Control humidity within % displayed, or pressure within inches W.C. or PSI. Outputs include 2 modulating and 2 relay outputs that can each have its own setpoint.
The T775P Special Boiler Model offers features like dedicated pump output, staging for up to 12 relays, digital output alarm, pump exercise, pump pre-purge and post-purge, warm weather shut-down, built-in scheduler, displayed run time and more.
The T775L Sequencer Model has 4 stages, plus add up to 2 optional 4-stage expansion modules for 8, or 12 stage operation. Control these relays anyway you like with one or two set points: 4-heat, 2-cool; 6 cool, 4-heat; whatever you need.
