Why is the temperature displayed on my ICM Controls Thermostat not accurate?

  If the temperature displayed on your ICM Controls Thermostat isn't accurate, there are a couple of things to check: * First, ensure the thermostat is set to your preferred temperature readout: Fahrenheit or Celsius. You can check if the 'jumper' is properly set. * Also, make sure to plug the hole for wiring behind the thermostat with non-flammable insulation. This prevents airflow into the thermostat, which can affect the temperature reading.
