UNIT OPERATING MODES
There are three different modes that control the supply fan and unit operation:
Off
Manual
Auto
There are also four different methods for controlling the operating modes:
a
remote control panel
with one or two rotating adjustment knobs (MRT and
MDT controls)
an intelligent room sensor and
BACview
panel with LCD display (MRT-Expert
controls)
an
BACview
panel with LCD display (MDT-Expert controls)
any of the these controls with an internet-based
WebCTRL
interface or other 3
rd
party building automation system
MRT Controls:
Modulating room temperature (MRT) control is the most basic AireLogic control for
room temperature. The MRT control system includes a
remote control panel
equipped
with 1 or 2 potentiometers, 3 or more pilot lights, and up to 2 switches.
AireLogic units configured for MRT or MRT-Expert controls will have a fixed
discharge temperature of 70°F if the room temperature sensor is disconnected or
otherwise fails to communicate with the unit control module.
UNIT OFF MODE
Off Mode is the default unit operational mode. To place the unit in Off Mode, rotate the
“temperature setpoint” knob on the
remote control panel
counterclockwise to the stop.
This will place the unit in the OFF mode and extinguish the “fan on” light. The OFF
mode prevents the unit from starting.
