The weather-dependent set-point denes the parameters for weather-dependent operation of the unit. When
weather-dependent operation is active the water temperature is determined automatically depending on the outdoor
temperature: higher outdoor temperatures will result in colder water and vice versa.
OTC Points system will use average outdoor ambient temperature in order to get the water temperature set-point. Water
set-point will be determined using the following rule.
