This document describes the operation and care of Baxter Proofer and Retarder/Proofer cabinets.
Function Description
The Baxter Proofer and Retarder/Proofer cabinets are designed to proof racks of dough products under controlled temperature and humidity conditions prior to baking. Standard proofers are equipped for proofing dough only. Retarder/Proofers, on the other hand, offer additional functionality: they can gradually thaw frozen dough and operate like a refrigerator to keep the interior cool, providing an excellent environment for storing dough. The cooler temperature slows yeast fermentation, preventing dough from rising. The Automatic Retard/Proof feature allows for programming retard and proof times in a single operation, offering flexibility.

Retarder/Proofer Advanced Controls:
- Manual Proof Operation: Similar to standard proofer.
- Manual Retard Operation:
- Sets temperature (34°F - 50°F).
- Sets timer.
- No humidity control; fixed humidity value used.
- Defrost cycle can be set via Parameter Setup Mode; "DEFR" flashes during active defrost.
- Automatic Retard and Proof Operation (Auto Mode):
- Programs Retard and Proof in one operation (single day or seven days).
- "Rest Period" and "Recover Time" are setup times before proof stage.
- After one cycle, unit runs Proofer mode; operator must resume next day's program.
- Allows review/edit of settings, activation/deactivation of daily programs.
- Programming is based on Proof cycle completion Time/Day, starting with Sunday.
Operating Parameter Setup:
- Accessed by holding TIMER NUMBER arrow button and pressing ON/OFF button (or HUMIDITY UP and ON/OFF simultaneously if timer keys are unavailable).
- Allows customization of temperature offsets, humidity offsets, min/max proof/retard temperatures, rest/recovery times, time format, daily/weekly cycles, and defrost settings.
Proofer Model Selection (Bootloader):
- Allows changing the proofer model (Config 1: Proofer (PW), Config 2: Retarder/Proofer (RPW), Config 3: Dehumidifying Proofer (DPC1S)).
- Accessed by turning off the proofer, then holding HUMIDITY DOWN, TEMPERATURE UP, and ON/OFF buttons for 5 seconds until "conF" is displayed.
- Configuration is saved by pressing ON/OFF.
Firmware Update (Bootloader):
- Requires a FAT formatted flash drive with "proofer.bin" file.
- Accessed by turning off the proofer, inserting flash drive, then holding HUMIDITY DOWN, TEMPERATURE UP, and ON/OFF buttons for 5 seconds until "conF" is displayed.
- Press TEMP UP/DOWN until "LoAd" is displayed, then HUMIDITY UP to start.
- Displays "UPdt", "Strt", then "Succ" for successful update or "Err" for failure.
