will provide additional heating capacity to the water circuit if the
heating capacity of the unit is insufficient due to low outdoor
temperatures, it also protects the external water piping from
freezing during cold periods.
3. Temperature sensors
Four temperature sensors determine the water and refrigerant
temperature at various points in the water circuit.
