8.3.4 Modbus Header Sensor
This optional feature allows users to monitor the combined system outlet temperature or the
system Tank temperature via Modbus. This feature requires a Modbus Temperature sensor
Module to read and transmit the temperature to the Manager unit. This feature also allows a
user to view the temperature in either ˚F or ˚C.
Each unit has the following Modbus Header Temp points available:
• MB Head Temp En: This menu allows the user to enable/disable the Modbus Header
Temp.
• Header Temp Addr: A user must enter Modbus module address. Default is 240.
• Header Tmp Point: A user must enter Modbus register point. Default is 14.
• WHM Header Temp: This menu item displays the Temperature.
8.3.5 Temperature Sensor Calibration
The Temperature Sensors screens allows you calibrate the unit’s temperature sensors to
achieve optimal performance. Complete the following to calibrate the temperature sensors.
Figure 8.3.5: Temperature Sensors Screen
Temperature Sensor Calibration Instructions
1. Go to: Main Menu → Calibration → Input/Output → Temperature Sensors.
2. Press the Sensor parameter and select the temperature sensor you want to calibrate. The
following sensors are available for calibration:
• Feed Forward
• Outside Temp
• Lower Inlet
• Exhaust
• Air Inlet
• Outlet
3. The selected sensor’s current reading appears in the Current Reading field.
4. If there is an independent way to measure the temperature, and it differs from the Current
Reading, enter an appropriate value in the Offset parameter.
8.3.6 Manual Mode Password Required
In order to prevent unauthorized or inadvertently setting the unit in Manual Mode of operation,
entering a valid password is required to set the Edge in Manual Mode. Any level password will
enable the Manual Mode. Manual Mode is a temporary state, and disables automatically once
the password expires, or after 1 hour of menu inactivity.
