Engineering Guide Specications
Unit mounted LED annunciators aid in diagnosing unit operation by indicating the water source heat pump operating mode
and alarm conditions. If there are no current alarm conditions, a green LED on the annunciator board will indicate occupied
unit operating mode. If an alarm condition exists, the MicroTech III SmartSource unit controller will send the fault condition
to the LED annunciator, which will assist in troubleshooting the unit. Heat pumps with the MicroTech III SmartSource unit
controller with a LonWorks Communication Module is designed to be linked with a centralized Building Automation System
(BAS) through a LonMark communications network for centralized scheduling and management of multiple heat pumps.
Wall-mounted room sensors are available to control the heating and cooling operation of each MicroTech III Water Source
Heat Pump.
