ECV2110056 Variable Air Volume Wind Box Valve Controller Modbus Communication Protocol

Product Overview

'Single key operation, module control' is ECOA Automation of company buildings, Design of HVAC control products

The design philosophy aims to provide users with diverse control options efficiently through simple button operations.

ECV2110056 The variable air volume bellows valve controller is a concealed installation that uses a single chip at the center

Mechanism andI/OPeripheral expansion circuit: Mainly includes:D/AConversion circuit, A/DConversion circuit and optoelectronic isolation circuit

Wait, Used to collect signals from sensors (static pressure, temperature setting scale, NTCtemperature, 0-10 Vdc)control

control, using internal proportional, integral, derivative(P+I+D)and dead zone control characteristics for accurate control. controller itself

includes: sensing system, proportional control system, calculation module, control module, alarm detection system……

etc.. mainly used in building monitoring, factory monitoring, air conditioning monitoring, used in buildings, factories, offices

public rooms, conference rooms, restaurants, hotels…… etc..

characteristics and parameter overview

optional use of panel or controller temperature

temperature display / temperature setting / temperature correction

motor overcurrent protection high limit /motor forced manual

maximum opening of air valve / minimum opening setting of air valve

air valve selectable opening feedback (0: 0-10V 1: 0-20mA)

static pressure display / static pressure setting / static pressure correction

selection of duct numerical input : two methods for pipe diameter and area

air volume display / Air volume setting and maximum air volume setting / Minimum air volume setting

Wind speed display / Wind speed setting
