Introduction
This manual provides information about the MicroTech® Open Protocol Master (OPM) Panel. It
describes the components, field wiring options and requirements, network commissioning procedures,
and service procedures. The OPM Panel is used when integrating two or more MicroTech unit or
auxiliary controllers into another company’s building automation system (BAS).
For specific information about unit or auxiliary controllers, refer to the appropriate MicroTech
controller installation manual (see Table 1). For installation and commissioning instructions and
general information on a particular unit, refer to its model-specific installation manual.

Notes:
1. The MicroTech Absorption Gateway (MAG) is an interface to McQuay absorption chillers, which use Sanyo controllers.
2. The MicroTech Communications Gateway (MCG) is an interface to McQuay water source heat pumps, which use MicroTech
2000™ controllers. When there are only MicroTech 2000 controllers, an MCG can substitute for an OPM Panel.

CAUTION
Static sensitive components. A static discharge while handling electronic circuit
boards can cause damage to the components.
Discharge any static electrical charge by touching the bare metal inside the control panel before
performing any service work. Never unplug any cables, circuit board terminal blocks, or power
