standard(s). Operation is subject to the following two conditions: (1)
this device may not cause interference, and (2) this device must
accept any interference, including interference that may cause
undesired operation of the device.
7. Control functions
The pump operation is controlled by temperature measured at the
wireless temperature sensor mounted on the hot water return line.
When the pump has mains connected it starts to circulate hot water.
During the first minutes of operation, up to 5 minutes, it learns the
system temperature, Tsys. On the basis of the system temperature,
the pump calculates the start and stop temperature:
Tstop = Tsys - 5 °F (maximum: 110 °F)
Tstart = Tsys - 16 °F
Example 1:
if Tsys = 110 °F (maximum: 115 °F) then
Tstop = 105 °F
Tstart =102 °F
Every 12 hours or at each power cycle the pump performs the
above sequence to calibrate and flush the system.
If system temperature, Tsys, is below 85 °F the pump operates with
5 minutes on and 15 minutes off cycles and Tstart and Tstop is
omitted.
If the temperature sensor is not paired or connected to the pump
the pump operates with 5 minutes on and 15 minutes off cycles and
can be used during commissioning etc.
