 If systems are not cooling or heating: 

1. Ensure the system is set in cooling, drying or heating mode. Any indoor units connected to an MXZ or "Multi-zone" outdoor unit should be in the same mode. All indoor units should be in heating or cooling not both. Indoor units can be in the OFF position if not being utilized without affecting other units. Also, ensure that the fan speed and the vanes or (louvers) are set to the automatic position on your remote control or thermostat. 
2. Verify power is on to the system. Ensure the breaker in your electric panel is in the ON position and not tripped. Also, verify the disconnect switch at the outdoor unit is in the ON position.
3. Check air filters in the indoor unit. (See video below on how to access them.) If they are dirty, clean them, if system operation does not improve, move to the next step.
4. Power down the outdoor unit by turning off the breaker in your electric panel or moving the outdoor disconnect to the OFF position. Wait ten minutes and restore power to the system. Put ALL indoor units on the desired mode (heating or cooling) set temperature to the max setting. (61 for cooling/85 for heating.) Wait ten minutes, if system is still not working properly, please call our store to arrange a service call. 603-524-2308
5. If thermostats are not working and display "WAIT" message. Please follow the steps above. In addition, remove the batteries from the thermostat and reinstall them. If message still persists, please call our store to arrange a service call. In the mean time, you can try the provided handheld remote controller to operate the systems. See video to the below on how to operate the remote for your system.
