Eco Alliance heat pump fault-code guide

The located DynaHeat manual cover lists several ECO identifiers, including exact registry models ECO-215LEB and ECO-260LS. Copy every character from the plate because LE, LEB, LS and LU suffixes distinguish products that can share a tank size without sharing a controller. Spacing introduced by the PDF extraction was normalised only after the complete strings matched. ECO-155LU and ECO-215LU remain unmapped: the LE-series source does not name those registry values, and the current warranty page’s broad range labels are not controller evidence.

The instruction manual says an LED on the operation panel turns on and an error value appears on the LED display when a fault occurs. The panel does not enter sleep mode while that value is shown. This behaviour gives owners time to photograph the complete indication without navigating an installer menu. Keep the A prefix and both digits. If the suggested owner-level recovery does not clear the condition, the table says a printed-circuit-board malfunction is highly likely and directs repeated faults to an authorised contractor.

PDF page 13 publishes A12 low-pressure protection, A13 high-pressure protection, and sensor-related A21, A22, A23, A25 and A26. A12 and A13 tell the owner to switch off power and reconnect, but the wording does not explicitly document a complete off-and-restored power-cycle sequence, so this site does not present a guaranteed reset. The sensor rows say automatic recovery. Frequent recurrence goes to an authorised contractor. No additional values are inferred from missing numbers or from visually similar imported controllers.

The cover spans ECO-135, 155, 215, 260 and 290 products with several suffixes, while the current register slice contains only four Eco Alliance models. Two are exact cover matches and two are LU variants. This site maps only ECO-215LEB and ECO-260LS. A current warranty statement that mentions LE, LU and LHPWH ranges establishes commercial support scope, not a shared circuit board. Owners of an LU plate should retain its displayed value for support but should not assume the seven-row LE dictionary applies.

Eco Alliance’s current warranty page provides assistance for named LE, LU and LHPWH ranges and publishes five-year system or tank periods with two-year component and labour terms, subject to the detailed product conditions. The older captured LE manual contains its own residential and commercial periods and contact details. Installation date and applicable terms therefore matter. Use the current support route with the model, serial, compliance certificate, purchase evidence and displayed A value rather than assuming the manual’s historical period controls every installation.

The code table comes from a publisher-identifiable Eco Alliance manual retained from a public installer library, while current support and warranty status come from Eco Alliance’s first-party site. That distinction preserves the source even if the host moves and avoids pretending a distributor is the manufacturer. The manual supplies exact covered names, display behaviour and seven error rows. It does not connect LU models to the same controller or disclose technician diagnostics for every sensor. The catalogue exposes those boundaries and keeps each literal row attached to the captured page.
