The Heat Recovery Enthalpy Suitability Determination module determines whether the conditions are suitable for using the heat recovery function for heating or cooling. This module uses outdoor air and return/exhaust air enthalpy to determine whether to use heat recovery. The return/exhaust air dry bulb temperature is adjusted by the amount of the Deadband/2 to make sure enough energy can transfer to justify the operation of heat recovery. The module compares the return/exhaust air temperature with the outdoor air temperature to make the decision. If any of the temperature or humidity inputs are unreliable, the heat recovery is set to not suitable.
