MR-AHU-HP
Application Speciic Controller
Both the MR-AHU and MR-HP controllers are application speciic
controllers (ASCs). The intention of the design is to reduce “total
install cost” through pre-engineered control algorithms and
simpliied installation requirements.

It is designed to operate in a stand-alone
coniguration or, with the support of a
communications network, as an integral part of
a comprehensive building automation system.
Also the MR-HP controller provides suficient
applications lexibility to address multiple heat
pump (HP) conigurations. It is designed to operate
in a stand-alone coniguration or, with the support
of a communications network, as an integral part
of a comprehensive building automation system.

• Plug-on terminals for a thermostat, communi-
cations, power, and four external inputs.
• Plug-on terminals for six external outputs.
• A 12-position DIP switch for setting up initial
application/ equipment conigurations.
• Indicator lamps for output status,
communications, power, and self-test.
