Dropair Pro7 — FCU thermostat interface.
All numerical Pro7 ratings above are historical values from the 2020 V1.2 guide. They are not a claim that every currently supplied Pro7 has the same configuration. Confirm the exact product label, load limits and wiring before selection.
The historical Pro7 guide describes interfaces for chilled-water fan coil units using AC fan motors. Pro7-AC covers documented on/off-valve arrangements; Pro7-DC covers documented modulating-valve arrangements with an AC fan motor. The DC model name does not mean that every DC fan motor is supported.
Record the pipe arrangement, fan motor type, valve type and load current. The guide directs 0–10 V DC-controlled fan motors to Pro6X. Compare the existing thermostat wiring with the documented solution and confirm the supplied Pro7 variant before ordering.
The guide documents 24 VAC smart thermostat connections using a matched cable and model-specific terminal configuration. It includes older Nest, Ecobee, Lyric and Control4 examples; compatibility with a current thermostat model must be checked separately. Test the original FCU, isolate power, complete wiring to the applicable instructions, then verify the available heating, cooling and fan functions.
The downloadable V1.2 guide is dated 10 November 2020. Use its technical information to identify the documented arrangement, and request current installation guidance for the supplied hardware. Do not use a Pro7 diagram for the separate HA-adapter simply because the housings appear similar.
