Perry TE541 Manual: Questions and Answers
How do I change the temperature setting on Perry TE541?
Press the up or down key to adjust the T set value. Each press changes the temperature by 0.1 degrees. The new value saves automatically.

What's the difference between proportional and differential modes on Perry TE541?
Proportional maintains stable temperature with variable heating cycles; differential uses on-off switching at a preset temperature difference.

|---|---|
| Modulating proportional | Cycles heating 7 to 20 minutes, maintains stable temperature |
| Thermal differential on-off | Switches heating on and off using hysteresis value 0.2 to 1.2 °C |
