Pairing a diesel heater remote: steps for each controller

How do I pair the remote to my diesel heater?

The steps depend on the controller, not on the heater brand. Find your panel on the controller pages first. The pairing screen itself is a good clue: each family shows a different word.

Steps from manuals

Controller	Pairing screen	Steps
Classic 5-button LCD	HFA	Hold up and OK for about 3 s until HFA shows. Press a button on the remote. The unit restarts when paired.
B2010	-PE-	In standby, press setting and up together. Long-press ON/OFF on the remote. The panel leaves pairing when matched, or after 20 s.
Vevor M-button panel (XMZ-D1, XMZ-D2)	rte	With the heater on, hold the up key for 3 s until rte shows. Press any key on the remote.
Knob LCD (Hcalory HC-A01)	rte, then P1 to P4	Open query item En08 (rte) and hold the knob for 3 s. As P1, P2, P3 and P4 appear, press plus, minus, mode and on/off on the remote.
Vevor CY 3-key LCD	HFA1	Heater off: hold the right key for 2 s. Left and right pick the remote number (1 to 4). Press any key on the remote. Power exits.
Vevor CY single-knob LCD	rF, then r1	Heater off: hold the knob 3 s, turn to rF and short-press. Turn to pick the remote number (1 to 5). Press any key on the remote.
Gasmate DH203	OC1	In standby, hold power and down for 2 s. Up and down pick the slot (OC1 is the first of up to 5). Press any button on the remote, then OK to confirm.
T4 two-knob switch	433	Heater shut down: hold the Time knob on the switch and the OFF button on the remote together. 433 shows and the buzzer sounds once.
Heatport H2 / H4 EnControl	Stu, then 433	Heater running in thermostatic mode: turn the rotary switch anticlockwise until Stu shows. Press OFF on the remote. 433 shows when paired.

Each row is from the manual for that panel. Manual Notes:

• Classic 5-button LCD. The row is from the OnTrack sheet. The Hcalory M98 manual gives the same key press for this panel and says to press the ON button on the remote. Manual One owner video shows it as hold OK, then press up until HFA. Owners
• Vevor M-button panel. The key icon is lost in the copy of the manual that was read. Hcalory’s M98 manual prints the same step for its own panel with an M key and names the up key. Manual
• Knob LCD. The row is from the Hcalory HC-A01 manual, whose transcription has lost the key icons for opening the query menu. A Likaci video of a knob panel with the same menu shows how to reach item 08: heater on, hold the setting key and the power key for 3 s, then turn the knob. Owners The two panels have not been compared side by side.
• Vevor CY 5-key LCD (H1 to H6 gears) and knob LCD with keys. The manual copy that could be read has lost the symbol for one of the two keys to hold, so the full step is not given here. On the 5-key panel one of the two is the power key, held with the heater shut down. The manual does say you then choose a remote number and press any key on the remote. Manual
• Liwolf 5-button LCD (H1 to H6 gears). Its manual has the same gap: with the heater off you hold the gear-down key for 2 s, apparently together with a second key that is missing from the copy, then set the remote number (1 to 5) and press any button on the remote. Manual

Steps from owners only

Controller	Pairing screen	Steps
Blue LCD with arrow keys	HFA	On the controller, hold the right arrow until HFA shows. On the LCD remote, hold power and OK together until it shows its connecting message.
H1 to H6 panel, Likaci 6-key variant	OC1	Heater off: hold power and down for 2 s until the matching prompt shows. Press any key on the remote.
Hcalory Toolbox panel	none	One review video says the supplied remote connects by itself, with no pairing step.

These rows come from videos, not manuals. Owners The blue panel steps appear in two owner videos, and no manual was found for that panel. The Likaci row is from the maker’s own video of its 6-key switch. The Vevor CY and Liwolf manuals do describe a five-key panel with H1 to H6 gears, which is probably the same design as the H1 to H6 panel in owner videos, but their pairing steps are incomplete in the copies read (see the notes above). Power and down for 2 s is also the Gasmate manual’s step. The Hcalory Toolbox row rests on a single review.

No pairing procedure is documented for the rotary knob controller.

My panel shows OC1 or never shows HFA. What then?

In one Reddit thread, three owners whose panels did not respond to the HFA method paired like this: Owners

• Two held power and down until the screen showed OC1, then pressed any remote button.
• One held power and the right arrow, which brought up OC.1 on their unit, then pressed any remote button.

One of the three could pair the original remote this way but not a second, replacement remote. All three reports are in a single thread, so treat this as one source. It does match the Gasmate manual, which uses power and down and shows OC1. Manual

Pairing fails. What should I check?

1. Remote battery. One owner who paired successfully reminds others to check the battery and to pull the plastic tab on a new remote. Owners Gasmate’s remote takes a 12 V A27 battery, and the Hcalory HC-A01 remote takes one 12 V battery. Manual
2. The right steps for the panel. Panels that look alike use different key presses. If the pairing screen in the table never appears, you are probably following another panel’s steps.
3. The right heater state. The Vevor M-button panel pairs with the heater on. The B2010, Gasmate and T4 pair in standby or shut down. The Heatport EnControl pairs only while running in thermostatic mode. Manual
4. The time limit. The B2010 leaves its pairing screen after 20 s without a key press. Manual Have the remote in your hand before you start.
5. Remote function switched on. One owner video of the Vevor Bluetooth panel shows a user menu with a remote on/off item. Owners If the remote is switched off there, pairing will not help.
6. A compatible remote. Vevor’s CY manual specifies a 433 MHz remote with a 24-bit code and calls the remote an optional function. Manual In the OC1 thread above, one owner could not pair a replacement remote at all. Owners
7. Power was disconnected. Gasmate’s manual says pairing must be redone each time power is disconnected and reconnected. Manual

No source gives a pairing distance, so none is quoted here.

How do I clear the stored remotes?

The Hcalory HC-A01 manual is the only one with a procedure: hold a key for 7 s during the power-on self-test until CLr shows, followed by SUC. Manual The transcription of that manual does not show which key.

On the blue panel, one owner video says pairing a new remote replaces the old one. Owners

When should I stop?

• The remote still does nothing with a fresh battery fitted.
• The correct pairing screen appears but the panel never accepts the remote. The remote may not match the panel. No source gives a fix for that.
• The controller itself is unresponsive: see controller screen is blank.
