Hcalory TB2S
Portable diesel air heater. Portable diesel heater. Error-code mapping depends on controller and accessory revisions; codes remain under verification.
MODEL TROUBLESHOOTING
Start with the symptom, then follow the checks
Hcalory has published conflicting E-code descriptions across heater and controller editions. These pages are research drafts until the TB2S controller-code table is confirmed.
Before starting: Combustion equipment can produce deadly carbon monoxide. Stop using a malfunctioning heater, keep people in fresh air if exposure is suspected, and never bypass exhaust or thermal protections.
Why is my Hcalory TB2S showing E08 and shutting down?
E08 is not defined consistently across Hcalory controller generations. Confirm the exact TB2S screen and firmware before treating it as flame-out or glow-plug failure.
Get step-by-step checks and outcomes →What should I check when my Hcalory TB2S shows E10?Do not assume E10 is universally a failed igniter: verify its meaning on the installed TB2S controller, then check safe external startup conditions.
Get step-by-step checks and outcomes →Why does my Hcalory TB2S show E07?A suspected E07 communications fault requires you to identify the exact controller type before reconnecting or replacing any display.
Get step-by-step checks and outcomes →Why does my Hcalory TB2S keep overheating and shutting off?If the heater cuts out hot, stop repeated restart attempts until fuel, air-path and protective shutdown conditions are known.

Safety and evidence notice: The TB2S error-code mapping is NOT confirmed across all controller revisions. Do not act on a single code description from another heater model. Carbon-monoxide safety protections must never be disabled.
