Summer / Winter Switch:
A Daikin supplied switch is attached to “ABC” terminals on the
external unit to allow manual changeover from a central location. This
is commonly found on sites with facilities managers or multi-tenant
sites such as hotels where heat pump was installed in an exclusively
cooling region.
3rd Part Ambient Sensor:
This option was developed to provide an automatic version of the
summer winter switch. A remote ambient sensor will dictate when
mode change occurs. Occasionally used in temperate climates where
budget constraints push the application towards heat pump but is an
option rarely seen in this market.
Note: Both the central mode control options above are only utilized on heat
pump systems.
