Operation Menus  

This menu is accessible through normal operation mode. The Mode Selector jumper (JP1) of the thermostat must be set to the 
“RUN” position (Operation Mode). Refer to Wiring on page 5.  
 
1.  Press the 

[*]

 and 

[

buttons simultaneously for 5 seconds. The 

“Enter Password”

 screen appears. 

2.  Enter the password within 1 minute by using the arrow keys to increase or decrease the value and the 

[*]

 and 

[

]

 buttons to 

toggle between the digits.

b.  Password

c. 

Password 

757

 = Airflow Balance Mode 

3.  If

 

you enter the wrong password, the 

thermostat displays “

Eror

” and returns to Operation Mode. The thermostat will return to 

normal mode if you navigate through the entire menu and do not make any selection, or if you do not press any key for 5 
minutes. The changed values will be saved automatically. 

Menu 372 

– Temperature Offset 

1.

 

“Intern Temp Sensor Offset” 

 

 

Range: 

 

Offset: 
Increment: 

10 to 40ºC  

[50 to 104ºF]   

Max ± 5ºC  

 

0.1ºC    

 

[0.2ºF] 

Compare the displayed temperature reading with a known value from a thermometer. To offset or calibrate the sensor, use the 
arrows key to set the desired temperature reading. This is useful for thermostats installed in areas where the temperature read 
is s

lightly different than the room’s actual temperature. For example, a thermostat placed right under the air diffuser.  

If the thermostat is set to use an external temperature sensor (

EtS

), the thermostat displays “OFF”.  

2.

 

“Extern Temper Sensor Offset” 

 

 

Range: 

 

Offset: 
Increment: 

0 to 50ºC   

[41 to 122ºF]   

Max  ± 5ºC 
 0.1ºC   

 

[0.2ºF] 

This option appears if you’ve set one of the analog inputs to 

EtS

 (External temperature sensor). When the thermostat is 

connected to the appropriate analog input, the display shows the temperature read by the external temperature sensor. Adjust 
the offset by comparing it with a known value (e.g. thermometer). If the sensor is not connected or short circuited, then the unit 
displays the sensor's limit.

 

  

3.

 

“Input3 Reading” 

 

 

Range: 

 

250mV (0") to 4000mV (1")   

Displays the voltage output value in mV of the pressure sensor. 

4.

 

“Input3 Minimum Reading 

 

 

Range: 

 

Default: 

10mV to 180mV 
60mV 

This setting represents the deadband of the pressure sensor in mV. For advanced users or special applications only. We 
recommend that you use the default setting of 60mV.
