Unit Operating Modes There are three different modes that control the supply fan and unit operation: • • Manual • Auto There are also four different methods for controlling the operating modes: • "a remote panel with two rotating knob adjustments (MDT and MRT controls) •...
Unit Operating Modes MRT Controls: MRT, modulating room temperature, is the most basic AdaptAire 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. UNIT OFF MODE Off Mode is the default unit operational mode.
Page 9
Unit Operating Modes UNIT MANUAL MODE Manual Mode allows the unit to turn on regardless of the Time Clock or Night Setback functions. A BACview or PC is required to change to this mode. See the section related to the MRT Expert for instructions on how to use the BACview for programming.
Unit Operating Modes to be "off" and the Cooling Night Setback function turns the unit "on", the unit will be cycled "off" once the room air temperature has fallen 2° below the Cooling Night Setback setpoint. The default for this setpoint is 100°F and is fixed at 27° above the Cooling setpoint.
Page 11
Unit Operating Modes for up to 4 separate On/Off events with any combination of days. The normal schedule sets the typical On/Off times for the unit. The holiday schedule can be programmed for up to 12 separate On/Off events with any combination of days. The holiday schedule sets the Off times for holidays and other shutdown periods.
Unit Operating Modes function is activated whenever a contact is closed between the appropriate terminals on the unit's terminal strip located in the unit's main control panel. Heating and cooling functions use the Night Setback Setpoints. See the Typical Wiring Schematic and Multiplexed Input sections of this manual for more information.

Unit Operating Modes Setpoint. The allowable temperature range is 55°F - 130°F . This sets the highest discharge air temperature that will leave the unit. If the maximum and minimum discharge temperature setpoints are set for the same temperature, the supply air temperature will be the same as the setpoint regardless of the room temperature setpoint or actual room temperature.
Unit Operating Modes with internal heat gain. In certain conditions it may be necessary to readjust the minimum discharge air or room temperature setpoint upward or adjust the outside/return air ratio to provide a warmer supply air temperature. Energy Savings Mode 1—Non-Recirculating Units. Energy Savings Mode 1 will automatically disable the burner if the outside air temperature is equal to or greater than the minimum discharge air temperature setpoint, and the room air temperature is 5°F above the room air temperature setpoint.
Unit Operating Modes line downward. If the room temperature falls to a temperature that is 2°F below the heating setpoint, the heating will be enabled, and the unit will be in the heating mode. Continue following the solid line in a clockwise direction to the heating setpoint.
Unit Operating Modes To change the desired cooling room temperature of an MRT-Pro control system, depress the Warmer button to increase the desired room temperature setpoint or depress the Cooler button to decrease the desired room temperature setpoint. Each push of a button changes the temperature setpoint by 1°F . The setpoint can be changed a maximum of ±10°F from the default of 72°F .
Page 17
Unit Operating Modes operating in the heating mode, the unit will automatically keep the minimum outside air at 20%. If the outside air drops below 20%, the burner will cycle off. See Minimum Ventilation. MRT-Pro Controls. To change the damper mode on an MRT-Pro control system requires the use of a BACview or PC.

Unit Operating Modes Building Pressure Mode The Building Pressure mode varies the percentages of outside air and return air to maintain a constant pressure within the space. A pressure transducer compares the pressure outside the space to the pressure inside the space and transmits a corresponding signal to the AdaptAire controller.
Functions 100% Outside Air The 100% Outside Air function automatically opens the outside air dampers and closes the return air dampers. This function is activated whenever a contact is closed between the appropriate terminals on the unit's terminal strip located in the unit's main control panel.
Functions User Configured PID Control This function is applicable to non-recirculating units only. The User Configured PID Control function allows the user to control an analog output based on a user defined analog input and setpoint. See the Typical Wiring and Unit Controller Specification sections of this manual for more information regarding the inputs and outputs.

Functions to the Max User setpoint. In this situation the output value is the greater of the PID output or the override output. If the input variable is below the User Control setpoint, the output could decrease from 100% to 0% as the input variable decreases from the User Control setpoint to the Min User setpoint.

Functions Unit Resets This section should assist the user in resetting alarms and cycle counters which have been displayed on the BACview. ALARM. To reset an alarm scroll through the menu tree, locate the Unit Resets branch and select Alarm. Press the Enter key. The word OFF should flash. Now press the INC key and the word ON should flash on the display.
Functions input. A switch is used in conjunction with each resistor. When a switch is closed, the resistance at the controller input changes. This allows the controller to identify which switch has closed. The controller is programmed to associate each different resistance with a specific function.
Diagnostics Critical Fault Codes This section should assist the user in troubleshooting critical fault codes messages that have been displayed on the local user interface. These faults require the operator to correct the condition and reset the alarm before normal unit operation resumes.
