Overview
The replacement user interface control panel (head unit) for ComfortBilt and Alpine stoves with the 4-pin data cable.
This is the screen and keypad you use to run the stove. Each version is loaded with the program for a specific model, so choose your stove model (or the program name shown on your current panel) from the menu. It works with the BC Innovate WiFi module.

| Brand | Models |

| Alpine | HP40, HP41, HP42 |
Read before ordering — all three must be true:
- Your stove uses the 4-wire (4-pin) data cable — not the serial ribbon style.
- Your PCM board shows a fully yellow transformer through the square window in its lid. Boards with a half-yellow / half-red transformer are not compatible.
- You have picked the matching model / program from the menu. The wrong program can make the stove run incorrectly.
Each panel is new and fully functional. ComfortBilt reuses plastic housings to cut waste, so the case may show minor scuffs that don't affect operation.
