Andover Controls i2 885 Controller

I N F I N E T I I 885 VAV Controller with Built-in Infinet II (i2) 885 is a unique, low-cost VAV box controller that comes with a built-in actuator to streamline hardware installation and commissioning time. Two universal inputs, an airflow sensor, two A triac-based outputs, and an integrated damper actuator, make controllers perfect for smaller VAV applications. to all i2 controllers, the i2885 features Flash memory and a fast processor for faster scan times. i2885 communicates with the entire Andover Controls Infinet field bus; i.e., both Infinet and Infinet II controllers, and is with Continuum CyberStation Version 1.5 or greater. Up to 254 devices can be networked to any Andover network controller. RELIABILITY WITH FLASH MEMORY i2885 non-volatile Flash memory stores your operating system and programs, so that in the event of a power loss, your will be restored when power is returned. In additon, the Flash allows for easy upgrades of your operating system via software eliminating the need to swap out proms. input configuration on the i2885 consists of two full range Universal that accept voltage (0-5VDC), digital (on/off), counter signals (up to or temperature signals, plus an on-board air flow sensor. Typically two inputs are used for room temperature, and either supply air or a setpoint adjustment signal. i2885 contains two Form A Triac-based outputs. Each Triac is ground These outputs can be used separately for on/off or pulsed of lighting, heat, and fan units or for bi-directional control of and valves; or configured into one Form K Tri-state output. are rated for AC loads only. Typically, the outputs are used for 1- 2-stages of electric heat, or a PWM reheat valve.

This eliminates the for separate mounting, wiring, and positioning the damper motor. All i2885 controllers have software over-drive protection which senses motor limit stall conditions and helps to motor damage. Also, the actuator has a clutch button to temporarily disengage the gears during commissioning. The i2885 may be preset for a limited range of using the mechanical provided. CAPABILITIES dynamic memory of the i2885 can be for any combination of programs, alarming, and data logging using the Andover Controls Plain English language. Our object-oriented Plain language with intuitive keywords provides easy method to tailor the controller to meet exact requirements. Programs are entered the i2885 using the Continuum CyberStation or user terminal. Programs are then stored in, executed by, the i2885. multiple i2885 is inherently easy Plain English. A complete copy of one i2885 can be loaded directly into other i2885 changing any point names or programs.
