None of the major players systems using R410a can control below 18c these days.

As mentioned by r.bartlett Qualitair Low temp Cassettes are one option.
Another are Marstair which are available in the more std 600 x 600 & 875 x 875mm Cassette chassis sizes. 10-18c control band.
However, they are a bit "old fashioned" by modern day standards e.g. R407c gas, non-inverter, elec-mech controls. Fit for purpose though.
