Velleman K2649 Manual: Questions and Answers
What does the R32 SENSOR terminal on the Velleman K2649 connect to?
The sensor wires soldered to the temperature probe. Connection order is unimportant unless using screened cable, in which case the screen connects to the side marked SENSOR. Instruction Manual, p. 14
How do I calibrate the Velleman K2649 temperature sensor?
Calibrate at two points using ice water and boiling water.
- Plunge the sensor into melting ice water until it reaches 0°C, then adjust RV2 until the display reads 00.0.
- Plunge the sensor into boiling water until it reaches 100°C, then adjust RV3 until the display reads 100.0.
- Let the sensor cool for about half an hour.
- Repeat the complete adjustment cycle once more. Instruction Manual, p. 16
What's the maximum cable length allowed for the Velleman K2649 sensor?
10 meters maximum. Screened cable is preferable to avoid interference. Instruction Manual, p. 13
What does a colon displayed on the Velleman K2649 LCD mean during setup?
A colon indicates the display is correctly mounted. A single point means you must rotate the display. Instruction Manual, p. 10
What do the J4 and J1 terminal blocks on the Velleman K2649 control?
J1 connects to mains power. J4 is the economy switch. Instruction Manual, p. 7
What do the C and NO contacts on the Velleman K2649 relay connect to?
Use C and NO for heaters. Use C and NC for coolers. Instruction Manual, p. 7
What is the maximum relay output voltage for the Velleman K2649?
240V, 3A maximum. Instruction Manual, p. 1
Can I mount the Velleman K2649 sensor inside a pipe or liquid?
Yes. Attach the sensor to the outside of a metal pipe or boiler using heat-conducting paste, or make it waterproof and immerse it directly in the liquid. Instruction Manual, p. 23
Should the Velleman K2649 sensor be placed in air circulation?
Air conducts heat poorly, so circulating air around the sensor improves its response time. In large rooms heated by hot air, position it near the convector inlet where intake air passes through it. Instruction Manual, p. 23
