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 6.
7. Press the
[*]
and
[
]
buttons simultaneously for 5 seconds. The
“Enter Password”
screen appears.
8. 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.
a. Password
372
= Temperature Offset Menu
b. Password

c.
Password

= Airflow Balance Mode
9. 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.
“
tS1
”
(temperature 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.
“
Ets"
(external temperature 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.
“
Prs
”
(input 3 reading)
Range:
250mV (0") to 4000mV (1")
Displays the voltage output value in mV of the pressure sensor. Does not appear for EVCB14NDT4S and EVCB14NDT4X
(pressure dependant) models.
4.
“
PRS MIN"
(input 3 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. Does not appear for EVCB14NDT4S and EVCB14NDT4X (pressure
dependant) models.
