Senville wall heat pumps: LETO, AURA or ELITE?

Senville’s three R-454B wall series, compared at the same capacity with the official figures: heat delivered at −15 °C, the coldest published point, seasonal efficiency and Hydro-Québec’s LogisVert amount. We help you choose, then install anywhere in Greater Montreal.

The smallest (AURA 6,000), the AURA 15,000 and the largest Senville wall units; the capacities differ, so no figure is marked. The LETO 30,000 and LETO 36,000 have a published point at −25 °C on NEEP, colder than the −15 °C Senville states for the series. The AURA 33,000 carries the largest LogisVert amount in the wall range: $3,840.

On R-454B, only the LETO 9,000 and 12,000 come in 115 V

Every other R-454B Senville wall unit sold here runs on 208/230 V. The 115 V LETO 12,000 needs a 19 A minimum circuit ampacity and a 20 A maximum fuse, per senville.ca.

Controls

CR322 or CR333 remote, Wi-Fi through a kit

CR322 remote for the LETO, CR333 for the AURA; the WRD-RMTIQ wired wall controller works with the AURA, not the LETO. Senville does not publish either point for the ELITE.

Wall units made since 2019 ship with an Alexa USB kit. The Senville app (NetHome Plus) needs a Wi-Fi kit sold separately and a 2.4 GHz network. See Senville Wi-Fi modules and thermostats

Questions

Questions from Senville’s help centre, answered with the figures

LETO or AURA: what is the difference?

Senville positions the LETO for one room and mild to moderate winters, down to −15 °C, and the AURA for colder climates, whole homes and multi-zone, down to −30 °C. On warranty, the LETO has 5 years on the compressor and 5 years on parts, the AURA 10 years on the compressor and 5 years on parts. At 12,000 BTU/h, the AURA delivers 11,500 BTU/h at −15 °C, the 115 V LETO 6,600 and the 208/230 V LETO 8,000.

Senville’s comparison leaves out the ELITE; the table above puts it next to the other two.

Question published by Senville: “LETO vs AURA: What is the difference between the Senville series?”, help centre, modified October 8, 2026; figures from ENERGY STAR and NEEP.
Which line set does my Senville wall unit need?

It depends on the capacity: 1/4" liquid and 3/8" suction from 6,000 to 12,000 BTU/h, 1/4" and 1/2" at 18,000, 3/8" and 5/8" from 24,000 to 36,000, except the AURA 33,000: 3/8" and 3/4". Senville names the first three kits PJX-1, PJX-2 and PJX-3, and publishes no sizes for the AURA 15,000.

Question published by Senville: “How to choose the right line set for your Senville system”, help centre, modified June 29, 2026.
Is my Senville wall unit pre-charged?

Yes: LETO and AURA wall units are pre-charged for 25 ft (7.5 m) of line set. Beyond that, a refrigeration technician adds the charge set out in the manual.

Senville help centre, pre-charge article, modified October 8, 2026.
How do I connect my wall unit to Wi-Fi?

The Alexa USB kit in the box works with the Alexa app only. For the Senville app (also called NetHome Plus), you need the Senville Wi-Fi kit sold separately, on a 2.4 GHz network: 5 GHz will not work.
