-- User safety: this contact is connected in series
with the water flow switch and can be used for any
customer safety loop.
-- Water pump control.
-- Alert indication: this volt-free contact indicates the
presence of a minor fault.
-- Alarm indication: this volt-free contact indicates the
presence of a major fault that has led to the shutdown of the refrigerant circuit.
Remote interface (accessory)
This accessory includes a box that can be mounted inside
the building. The power supply is provided via a 220 V/24 V
transformer supplied. This interface allows access to the
same menus as the unit interface and can be installed up to
300 m from the 61AF unit.

Outside temperature: For transport and storage of the 61AF units the minimum and
maximum allowable temperatures are -20°C and +50°C. It is recommended that these
temperatures are used for transport by container.

Maximum flow rate at an available pressure of 15 kPa.
Maximum flow rate at a water temperature difference of 3 K in the plate heat
exchanger.
Note: For a domestic hot water application (leaving water temperature = 65°C), the water
temperature difference must be at least 8 K for operation at 100% capacity.
