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.
