B2010 diesel heater controller: E-01 to E-12, F codes

Updated

The B2010 follows the common E-01 to E-10 meanings and adds detail. Its manual states voltage limits for E-01 and E-02, splits several faults into short-circuit and open-circuit sub-codes, and adds E-11 (ambient temperature sensor) and E-12 (controller overheating).

Is this your controller?

E-03

Also called: B2010, spanner-button controller, P-01 controller

A black five-button panel laid out like the classic LCD, but its setting button is marked with a spanner. In manual mode it shows gears such as P-01 instead of a Hz figure, and the screen sleeps after 5 minutes. Its fault codes go beyond E-10, to E-11 and E-12, and some carry an F1, F2 or F3 suffix.

How it shows a fault: E-01 to E-12 on screen. Glow plug, pump, fan and case-sensor faults add F1 (short circuit), F2 (open circuit) or F3.

Reported on: sold as a spare B2010 controller; heater brands are not stated in the manual.

Procedures on this controller

Pair the remote Manual

In standby, press setting and up together; the panel shows -PE-. Long-press the ON/OFF button on the remote. The panel leaves pairing by itself when matched, or after 20 s.

Full guide

Prime the fuel line Manual

In standby, press setting and down together; the screen shows a time such as 020. Setting selects the digit and up and down change the seconds, up to 999. Short-press OK to start or stop pumping; power exits.

Pump in short bursts and stop when fuel reaches the heater. Over-priming floods the burner.

Full guide

Switch manual and constant-temperature mode Manual

Press and hold up and down together. A flashing temperature means thermostat mode; P-01 means manual gears.

Parameter page behind the password Manual

After the password a four-character parameter such as P1H2 is edited one position at a time. The second character sets 12 V or 24 V parts and the third sets 5 kW or 2 kW. Leave with the power button; if the menu times out after 20 s nothing is saved.

Write down the original parameter before editing it.

Known quirks

  • The manual states the E-01 and E-02 limits: under 10 V or over 17 V on 12 V systems, under 18 V or over 32 V on 24 V systems.
  • No pump-Hz or fan-speed tuning and no altitude setting appear in this manual.
