S2 : Setting range from 10°C to 100°C. Default setting
60°C
S2 : Switching differential : Setting range from 1°C to
20°C. Default setting 2°C
S3 : Setting range from 10°C to 100°C. Default setting
60°C
S3 : Switching differential : Setting range from 1°C to 20°C.
Default setting 10°C, in mode-2 and mode-3
Default setting 2°C, in mode-4
14. TIMER function
Active only in the operating mode -2 or 3, ON/OFF controls to the time setpoints in the
Output B (S3). For solar collector systems with auxiliary heating. Enable or disable this
function is selectable. When the TIMER function is enabled, 2 ON-OFF(program-periods)
/Day provided, program-resolution : 10 minutes. Default setting : OFF
15. Temperature sensor cable
Collector sensor S1 --- PT1000, 1KΩ at 0°C, Temp. Coefficient 3.9x10 / °C. Resistance
variable rate 0.3851Ω/°C. Temperature display range -40~ + 250°C/-40~482°F, Accuracy
±0.5 °C/1.0 °F. Cable length:2meters,thermal-resisitve PTFE shielding
Tank sensor S2 --- NTC, 10KΩ at 25°C.
Temperature display range -10 ~ +110 °C/-14 ~ 230°F
Accuracy ±0.5 °C /1.0 °F. Cable length : 1,5 meters , thermal-resistive PTFE shielding.
Tank sensor (thermostatic) S3---NTC, 10KΩ at 25°C.
Temperature display range -10 ~ +110 °C /-14 ~ 230°F. Accuracy ±0.5 °C /1.0 °F. Cable
length : 1,5 meters, thermal-resistive PTFE shielding.
16. Temperature sensor's calibration : Offset (The same Offset range in all 3 sensors)
Range : -10°C ~ + 10°C,default setting 0°C
17. Build-in Rechargeable battery for retaining the settings and the time during power outages
18. Stand-By mode
Manually turn the unit ON/OFF (Output A&B can be turned-on/shut-off manually)
19. Key-lock function
Lock out of all the buttons on the front control-panel, prevents the settings from being
tampered with.
20. Anti-Legionella function
Effective only in S3. used for control the auxiliary heating.(Control of Output B).
This function will operate manually only, when it is in operation, Output B will be turned
on to heat up the water. When the water temperature reaches the setpoint, Output B will
continue to operate for a duration of (1080- (12x Anti-legionella temperature setpoint))
Seconds. After, the unit will resume its normal operation.
Anti-legionella temperature setpoint: Setting range from 60°C to 90°C. Default setting
70°C
21. Blue backlit LCD, auto mode 10 seconds
