Offsets
Temperature Offsets
– This option allows calibration (or
deliberate miscalibration) of the room temperature
sensor(s). There are various reasons why the
displayed temperature would be adjusted to a higher
or lower value. NOTE: Do not adjust for 30 minutes
after installation because board may be heated by
handling. The selected number is the number of
degrees, plus or minus, which will be added to actual
temperature. The numbers can range between -5˚ and
+5˚. Default values are set to 0˚ offset.
Temperature Offset
Remote Indoor Offset (if sensor is attached)
Outdoor Offset (if sensor is attached)
Humidity Offset
– This option allows calibration of the
humidity sensor. Adjustments can range between -10%
and +10%. Default is 0% offset.
Auto Changeover
With auto changeover, the thermostat automatically switches
itself from heating to cooling, or vise versa, based on the
setpoints. When setting up the thermostat you have to enter
both a cooling setpoint and a heating setpoint. The thermostat
will also prevent the user from setting the cooling setpoint lower
than the heating setpoint. Mode is set to AUTO for this operation
to work.
Auto Changeover Time
– This setting sets the minimum off
time before the thermostat can change from one mode
to another. Default is 5 minutes. Range is from 5-125
minutes in 15 minute increments.
Auto or Manual Change
– Default is AUTO. If MANUAL
is chosen, you will need to change from heating to
cooling or vise versa. When MANUAL is set, AUTO is
removed from the MODE screen as a choice.
USB
Allows Import and Export of Installer Settings, User Settings,
Program, and Dealer Details. If configured as a zone thermostat
this can also be done at the MasterStat.
°F / °C
(NOTE: This option is not available if configured as a Zone
Thermostat, but is available at the MasterStat.)
This screen changes the unit of measurement that is displayed
on the thermostat. Fahrenheit is the default setting.
Installer Setting Page Four
Press NEXT button. It will bring you to the Installer Setting page
four.
Residential/Commercial
For future use
Energy Demo Mode
(NOTE: This option is not available if configured as a Zone
Thermostat, but is available at the MasterStat.)
This screen is used for demonstration purposes only. It allows
the installer to show the user what those screens will display
once their system is running for the time periods shown (if
equipped with energy monitoring). Energy Demo is located
in the installer setup screen on page 4 of 4. In the weekly
screen, the seven days usage will be displayed across the top,
and the current day and daily average will be displayed along
the bottom. In the monthly screen, the 12 months usage will
be displayed across the top, and the current month, monthly
average, and annual total will be displayed across the bottom.
These are just images representing energy usage, not actual
data from the system. You can view both the weekly and
monthly data. After approximately 5 minutes of inactivity, the
demo mode will exit and go back to the home screen.
Thermostat Fault Codes
NZ-1
Humidity temperature sensor open
NZ-2
Humidity temperature sensor shorted
NZ-3
Outdoor temperature sensor error
NZ-4
Humidity reading too low
NZ-5
Humidity reading too high
NZ-6
Humidity sensor failure
NZ-8
Remote room sensor error
NZ-9
Primary temperature sensor open
NZ-10
Primary temperature sensor shorted
NZ-11
Temperature reading too low
NZ-12
Temperature reading too high
NZ-13
ABC control no communication
NZ-14
Low voltage under 19VAC
NZ-15
Low voltage under 16VAC
NOTE:
If you experience an NZ-11 fault, it is because the
ambient temperature is below 40°F. To protect the compressor,
only auxiliary electric heat will be available. Once the set point is
met, the auxiliary electric heat will turn off, and the compressor
will operate as intended.
