1 SAFETY CONSIDERATIONS

1.1 General

Installation, start-up and servicing of equipment can be hazardous if certain factors particular to the installation are not

considered: operating pressures, presence of electrical components and voltages and the installation site (elevated plinths

and built-up up structures). Only properly qualified installation engineers and highly qualified installers and technicians,

fully trained for the product, are authorized to install and start-up the equipment safely. During all servicing operations

all instructions and recommendations which appear in the installation and service instructions for the product, as well as

on tags and labels fixed to the equipment and components and accompanying parts supplied separately, must be read,

understood and followed.

•Apply all standard safety codes and practices.

•Wear safety glasses and gloves.

•Use the proper tools to move heavy objects. Move units carefully and set them down gently.

1.2 Avoid Electrocution

Only personnel qualified in accordance with IEC (International electro technical Commission) recommendations may be

permitted access to electrical components. It is particularly recommended that all sources of electricity to the unit be shut

off before any work is begun. Shut off the main power supply at the main circuit breaker or isolator.

2 CONTROLLER DESCRIPTION

HHFlex controller is an electronic control system to regulate Air Handling Units.

The control system consists of two controllers which are described hereafter.

2.1 Overview

Controller Overview

Port 2 and TCP/IP are only available on the main controller

2.2 Power Supply

Each controller operates at 24 VDC and has a power consumption of 4 VA (without load, without display).

In the event of a power supply interrupt, the unit restarts automatically without the need for an external command. However, any

faults active when the supply is interrupted are saved and may in certain cases prevent unit from restarting.

2.3 Battery

The resources and the program are stored in RAM. To ensure that they are not lost and that the hardware clock

continues to run when there is a power failure, the controller is equipped with a buffer battery.

The buffer time is at least 5 years.

The buffer battery is a 3V lithium battery (CR2032).

The battery voltage is monitored. When battery is low the P/B Indication LED lights red.

2.4 Indications

The upper left corner of each controller contains four LEDs which give the status indication of the controller.
