IM 991-2 • MAVERICK II ROOFTOP

Entering Fan Temperature Sensor

The entering fan temperature (EFT) sensor and an associated “Lo 

Airflow Problem” alarm are provided on VAV units with MicroTech 

III control and gas or electric heat. The EFT sensor is located in 

the supply fan section of the unit at the supply air funnel. 
Heat is disabled whenever the airflow is detected to be too low 

for safe heating operation. This condition is indicated when the 

supply air temperature exceeds the mixed air temperature by 

more than 60°F (16°C). 

NOTE: 

This value is not always 60°F. It depends on whether 

the unit is gas or electric heat and on the burner/

baffling arrangement on gas heat units. 
In this case, a “Lo Airflow Problem” alarm is 

generated and heat is not enabled until the alarm 

is manually cleared. Refer to the operation manual 

supplied with the unit for information clearing alarms 

(

OM 920

). 

Duct High Pressure Limit

The duct high pressure limit control (DHL) is provided on all 

VAV units.The DHL protects the duct work, the terminal boxes, 

and the unit from over pressurization, which could be caused 

by, for example, tripped fire dampers or control failure. 
The DHL control is factory set to open when the discharge 

plenum pressure rises to 3.5" wc (872 Pa). This setting should 

be correct for most applications; however, it is adjustable. 

Removing the front cover of the device reveals a scale showing 

the current setting. Turning the adjustment screw (located on 

the bottom of the device) adjusts the setting up or down. 
If the DHL switch opens, digital input MCB BI 14 on the Main 

Control Board de-energizes. The MicroTech III controller then 

shuts down the unit and enters the OFF-Alarm state. The 

alarm must be manually cleared before the unit can start again. 

Refer to the operation manual supplied with your unit for more 

information on clearing alarms (

OM 920

). 

Variable Frequency Drive Operation

Refer to the vendor instructions supplied with the unit.
