TROUBLESHOOTING
This section contains information to assist you in troubleshooting problems and errors associated with the WeatherMaker
Step 1ÐSystem Diagram, Jumpers, and Switches
→NOTE: For correct control board operation, it must have either a sensor attached or a 10k resistor in place at the duct and HP inputs.

High Heating Temperature Trip Limit Setting Ð B When DTO is On, temperature is sensed by duct temperature sensor. When the duct temperature reaches this temperature setting, the duct temperature
optimizer is enabled.
If the LAT is exceeded then heating will turn off.
NOTE: HP temperature sensor is recommended for all heat pump applications.
