SAP 10.2 Table 4e (PDF p.170-173) "Heating system controls":
3. The 'Temperature adjustment' modifies the mean internal
temperature and is added to worksheet (92)m.
SAP 10.2 Table 9c step 8 (PDF p.184): "Apply adjustment to the mean
internal temperature from Table 4e, where appropriate".
Pre-slice the cascade hardcoded `control_temperature_adjustment_c
=0.0` at all three call sites of `mean_internal_temperature_monthly`
and `space_heating_section_with_results`. The §8 heat loss calc
therefore drove off (92)m unchanged → §8 SH demand under-counted on
every cert whose `main_heating_control` lodges a non-zero adjustment.
Table 4e adjustments by code (full p.170-173 coverage):
Group 0 — No heating system:
2699: +0.3
Group 1 — Boilers with radiators/UFH (+ micro-CHP):
2101, 2102: +0.6 (no thermo / programmer-only)
2103..2113: 0
Group 2 — Heat pumps:
2201, 2202: +0.3
2203..2210: 0
Group 3 — Heat networks:
2301, 2302: +0.3
2303..2314: 0
Group 4 — Electric storage:
2401 (Manual charge): +0.7
2402 (Automatic charge): +0.4
2403 (Celect): +0.4
2404 (HHR controls): 0
Group 5 — Warm air:
2501, 2502: +0.3
2503..2506: 0
Group 6 — Room heaters:
2601: +0.3
2602..2605: 0
Group 7 — Other systems:
2701, 2702: +0.3
2703..2706: 0
New `_control_temperature_adjustment_c(main)` helper consults
`_CONTROL_TEMPERATURE_ADJUSTMENT_BY_CODE` (52 entries, full Table 4e
coverage). Strict-raises `UnmappedSapCode` on present-but-unmapped
codes per [[reference-unmapped-sap-code]] so spec-coverage gaps
surface at test time. The helper is wired to all three call sites
of the MIT/SH orchestrators in cert_to_inputs.
Corpus impact — closes the +2.5 SAP cluster substantially:
Variant | control | pre → post | delta
------- | ------- | -------------- | -----
e3 (401)| 2401 | +2.55 → -0.09 | -2.46 (massive close)
e6 (404)| 2402 | +1.33 → -0.17 | -1.50
e7 (408)| 2402 | +1.29 → -0.20 | -1.49
e2 (524)| 2502 | +0.47 → -0.18 | -0.65
e5 (402)| 2402 | +0.07 → -1.43 | -1.50 (regressed —
previously net-zero
from offsetting bugs)
Cumulative |ΔSAP| across these 5: 5.71 → 2.07 (-3.64 pts closed).
electric 3 / 6 / 7 / 8 / 9 now all within 0.20 SAP of worksheet.
Golden fixtures unchanged (API certs in those tests don't lodge
non-zero-adjustment control codes; suite stays 888 pass).
Extended handover suite: 888 pass, 0 fail (was 887 + 1 new AAA test).
