1. ABOUT STRYKER VAV
1.1 Overview
The Honeywell Stryker VAV devices are configurable Lon
controllers that can be used to control VAV Zone terminal
boxes. These controllers also provide 2 freely configurable
PID loops to make use of any free pins in the controller. This
document describes how to configure and troubleshoot the
Stryker VAV devices using the AX Wizard. This includes
detailed descriptions of the various fields available in the
Wizard to configure an Stryker VAV controller and also a
description of the options available to check-out the points
after initial configuration.
1.2 Features available in the Stryker
VAV Configuration Tool
You can perform the following operations using the tool:
— Set up the Stryker VAV controllers on the network
— Configure the Stryker VAV controller for the target
application
— Create applications to program the controller
— Download the configuration to the controller
— Calibrate inputs and check outputs in manual mode
— Set the time in the controllerMonitor errors and alarms
logged in the controller
— Perform online operations like sensor calibration, con-
troller diagnostics, airflow balancing, and custom wir-
ing.

PID Proportional-Integral-Derivative (PID) values regulate an analog output based on two analog values
(one is a controlled variable; the other, a reference variable) and operating parameters.

DLC Demand Limit Control
The purpose of DLC is controlling the demand so that it does not exceed the maximum contracted
demand limit.
OAT Outdoor Air Temperature
K factor Constant Factor

Reheat Reheat is used for heating purpose in case of single duct, and only in cold regions, where heating is
required.
Night Purge During night time, the outside temperature is lower than supply air temperature. Night purge is a
process of flushing the building directly. In this process, outside dampers are opened and return air
dampers are closed and all exhaust fans are operated in full speed. It is used to save the Energy
saving and to improve the indoor air quality.
Emergency Purge If high temperature relief is required, the Emergency purge relief is required in case of high
temperature relief, and it can be triggered by lowering the temperature or through lowering the
pressure.
