1. SCOPE
This document provides installation, operation, maintenance and technical specifications for the DRI-
1000-A advanced ERV controller. Model DRI-1000-A is designed for specified Desiccant Rotors
International–US (DRI-US) ERV systems.
1.1. OVERVIEW
The DRI-1000-A consists of up to four accurate relative humidity/temperature (RH/T) sensors and a
microprocessor controller with LCD display to process the raw sensor signals and provide a PID loop
output control signal to the host energy recovery ventilation (ERV) system for media wheel speed control.
Both analog and RS-4 5 outputs are available from the DRI-1000-A for interface with virtually all modern
building automation systems. In addition, the Controller will accept up to two model S-110 air flow
sensors for indication of critical outside/exhaust airflows at the enthalpy wheel face. A programmable
alarm feature provides local and remote alarm/notification when outside air flow falls below a preset limit,
or if no enthalpy wheel rotation is detected by the (customer provided) wheel speed sensor in the host
ERV system. The programmable alarm output feature can be set to provide dry relay contacts (N.O. or
N.C.) or direct LED drive current (15 mA typical) for a wide range of alarm interfaces.
The DRI-1000-A is available with optional air flow probes and RH/T sensors as shown in Figure 1. Table
1 lists the system model codes and the sensors/probe complement provided with each model.
