Outdoor air dynamic cool set point.
CO2
Control
Config –
CO2 Parts Per Million (PPM) set points and sensor settings.
• PPM Low/High –
CO2 Parts Per Million (PPM) threshold set points for the space.
• PPM Limit
- CO2 Parts Per Million (PPM) threshold limit set points.
• Sensor Min/Max –
Set minimum and maximum range setting for CO2 sensor.
Active Faults
– Contains the current faults on the board.
Fault History
– Displays time-stamped history of the last 20 faults, most recent fault showing first.
Reset Lockouts
– Displayed when a lockout fault has occurred. Enter menu to reset fault(s).
FACTORY SETTINGS
NOTE: Password to enter factory settings menu is 1111
Temperature Control
– The MUA board monitors temperature control components.
• Temperature Mode
– There are five options for controlling the output of the unit in heat/cool tempering
mode. These options are Discharge/Space/Analog/Direct Digital Control (DDC). Refer to
.
• Activate Based On
– The unit can be set to “Activate On” during the following temperature readings:
Intake/Space/Both/Either/Stat (field installed thermostat). These settings can be altered for occupied
and unoccupied preferences.
• Construction Mode
– Configurable option for units used in construction settings.
Heating Config
– Allows the user to set various heating configurations.
• Heating Type
– Selectable range: None, Indirect, Heat Pump, Electric, HP & Ind, HP & Elec, HP or
Elec.
• Heat Hyst
• Space
– Space tempering sensor must go this amount of degrees above the set point before
heating turns off.
• Intake
– Intake tempering sensor must go this amount of degrees above the set point before
heating turns off.
• 2nd Disch Sensor
– On/Off selection. When an additional thermistor is added, the two thermistor
readings will be averaged together.
• Input Source
– This lets the board know what signal (volts or milliamps) to expect from the analog
control system.
• Gas Heat Config
• # of Heat Stages
– Default is set to 0 for units without gas heat. Select 1 for units equipped with gas
heat. Select 2 for units equipped with gas heat and high turndown.
• Relay Delays
• ROT
– This is the time after a furnace loses a call for heat before the furnace shuts down.
• RCT
– If the heat stage value is greater than 1, the user may adjust Relay Close Time (RCT)
delay for stages.
• Powervent Config
– The power vent operation may be set to operate in modulation mode or in an
ON/Off mode. The available settings are Triac Mod, PV On Off, or PWM Mod.
• Furnace Float
– Monitors the water level from condensation in the drain pan. Default is Off, select
On if a switch is installed on the unit. Required on high-efficiency furnaces.
• High Turndown
– Enable this option to On when the unit is equipped with a split furnace.
