The microprocessor temperature controller Krypton DHW is designed to control the operation of a central heating boiler equipped with a blower; it stabilizes its temperature by smoothly regulating the blower speed, performs boiler purges (to remove excess gases produced during combustion), and protects the central heating system from water overheating. Krypton DHW controls the operation of the central heating pump and the pump loading the Domestic Hot Water tank (DHW pump)
TECHNICAL DATA:
1. Measuring element in boiler and DHW temperature sensors
2. Boiler temperature setting range* 35*÷90 °C
3. Maximum blower speed 1 ÷ 50 steps
4. Purge time (possibility to disable purge) oF...5÷59 s
5. Pause time between purges 1÷30 min
6. Boiler temperature hysteresis 1.0 °C
7. Circulation pump activation temperature 25÷70 °C
8. Boiler temperature hysteresis 1.0 °C
9. Emergency thermostat activation temperature
– external/internal equipment ~90/~93 °C
– programmed 93 °C
10. Ambient temperature during controller operation 5÷45 °C
11. Supply voltage ~230/50 V/Hz
12. Temperature sensor operating range 0÷100 °C
13. Output load capacity: pump ~230V / blower ~230V 100/100 W
14. Power consumption (controller only) 2 W
15. Pump activation at low temperatures below 5 °C
16. Pump activation every 14 days for 1 minute - prevents pump seizure after the heating season (this function requires the controller to be turned on)
