Programmable, VAV/Unitary Controllers

 

PRODUCT DESCRIPTION

The PUB6438S, PVB6436AS and PVB6438NS controllers are 

part of the Spyder family. The three controllers are BACnet 

MS/TP network devices designed to control HVAC equipment. 

These controllers provide many options and advanced system 

features that allow state-of-the-art commercial building 

control. Each controller is programmable and configurable 

through software.

These controllers are for use in VAV (Variable Air Volume) and 

Unitary HVAC control applications. Each controller contains a 

host micro controller to run the main HVAC application and a 

second micro controller for BACnet MS/TP network 

communications. Each controller has flexible, universal inputs 

for external sensors, digital inputs, and a combination of 

analog and digital Triac outputs. The three models are 

described in Table 1. The photo to the left is the model 

PVB6436AS, which includes the actuator.

Table 1. Controller configurations.

Each controller communicates via an EIA-485 BACnet MS/TP network communications network, capable of baud rates between 

9.6 and 115.2 kilobits.
Controllers are field-mountable to either a panel or a DIN rail.
