Program Features

The microprocessor controller offers control through 
easy monitoring and adjustment of unit parameters by 
way of a lighted graphical display and an integral push-
button keypad.

Pre-Programmed Operating Sequences

The controller has been pre-programmed to offer 
multiple control sequences to provide tempered air. 
Factory default settings allow for easy setup and 
commissioning. The sequence parameters are fully 
adjustable. Refer to the Sequence of Operation for 
details.

BMS Communication

The user can remotely adjust setpoints, view unit status 
points and alarms. The microprocessor controller is 
capable of communicating over several protocols:
 • BACnet® MSTP 

• Modbus RTU

 • BACnet® IP 

• Modbus TCP 

Reference Points List for a complete list of BMS points.

Built-In Occupancy Schedule

The controller has an internal programmable time clock, 
allowing the user to set occupancy schedules for each 
day of the week. The controller option also has morning 
warm-up and cool down capability for improved 
comfort at the time of occupancy.

Alarm Management

The microprocessor controller will monitor the unit’s 
status for alarm conditions. Upon detecting an alarm, 
the controller will record the alarm description, time, 
date, and input/output status points for user review. 
Alarms are also communicated via BMS (if equipped).

Introduction

Occupancy Modes

The microprocessor controller offers three modes of 
determining occupancy: a digital input, occupancy 
schedule or the BMS. If in the unoccupied mode, the 
unit will either be shut down, continue normal operation 
utilizing adjustable unoccupied setpoints, recirculate 
with unoccupied setpoints or will cycle on to maintain 
adjustable unoccupied space temperature and humidity 
setpoints (space temperature and humidity sensor is 
optional).

Remote Unit Access (if equipped)

The WebUI and Remote Display are two ways to gain 
access to the unit controller allowing monitoring of the 
unit and parameter adjustment without being at the 
unit. 
The WebUI can be accessed via a building network 
and is included with every unit controller. The Remote 
Display is an LCD to be panel mounted in a remote 
location and is an option available for purchase.

WARNING

Electrical shock hazard. Can cause personal injury or 
equipment damage. Service must be performed only 
by personnel that are knowledgeable in the operation 
of the equipment being controlled.

WARNING

Mechanical high static protection cutoffs must 
be installed by others to protect the system and 
equipment from over-pressurization when using 
factory provided control sensors. The manufacturer 
does not assume responsibility for this.
