In any of the standard operating modes, the LED remains permanently lit.
5.4 Standby mode
Turn the knob to the lowest position in order for the pump to enter the standby
mode after the air purge function is completed.
Turn the knob to desired setting to return to standard operating mode.
5.5 Activate the air purge function
The air purge function does not start automatically at power-on. To activate the
air purge function, do the following:
1. Turn the knob to the highest setting.
2. After 5 seconds, turn the knob to the desired setting.
For air purge indication, see Display messages on page 21.
After the air purge cycle, which takes approximately 10 minutes, the pump will
return to the previous standard operating mode.
To exit the air purge cycle and return to a standard mode before completion,
turn the knob to the middle position and then to the highest position in one
second.
5.6 Typical speed settings
The typical speed settings are derived from hydraulic calculations of the heating
system. If those calculations are not available, then the following speed settings
can be used as approximate values:
• Standard single-family home:
– Approximately 1500 ft² @ 15.85 Btu/hr/ft²
– 23,775 Btu/hr (approximately 140 m² @ 50 W/m² = 7 KW)
– Set knob position to 2
• Apartment block:
– Approximately 4518 ft² @ 15.85 Btu/hr/ft²
– 71,616 Btu/hr (approximately 420 m² @ 50 W/m² = 21 KW)
– Set knob position to 3
Note: If the temperature differential between the discharge and suction is too
large, increase the speed setting; but if the temperature differential is less than
expected, reduce speed setting.
• Guideline values:
– Underfloor heating: 14.4–18°F (8–10°C)
– Radiator heating: 27–36°F (15–20°C)
