5.17 Warming up function
5.17.1 Warming up function
This function maintains the circulating fluid temperature to the set
warming-up temperature with heat generated by automatically
operating the pump in the winter season or at night.
When the time required for increasing the temperature of the
circulating fluid needs to be shortened at startup, set this function ON
in advance.
- The pump automatically keeps operating until the circulating fluid
temperature becomes 2
o
C higher than the set warming up temperature.
- The pump automatically stops operating when the circulating fluid
temperature becomes 2
o
C higher than the set warming up temperature.
- The pump automatically restarts operating when the circulating fluid
temperature decreases 2
o
C lower than the set warming up temperature.
When the warming up function is set ON, the [RUN] light repeats turning ON
for 0.5 seconds and OFF for 3 seconds while it is on standby (when the
pump is not operating).
The [RUN] light blinks every 0.3 seconds during the automatic operation of
the pump.
The default setting of this function is “OFF”.
Note that when the warming up function is ON, the warming up function has
a priority over the anti-freezing function, and the anti-freezing function will
not be activated.
Keep the power supply ON for this function.
This function does not operate when the power is OFF.
z This function can be activated only when the power supply is ON
and the thermo-chiller is not operating.
z Fully open the valve or manual by-pass valve that is arranged by the
user to make it possible for the circulating fluid to circulate when
the pump starts automatic operation.
z
In extremely cold weather, the circulating fluid temperature may not
increase to the set temperature.
z During the automatic operation, the pump does not stop operation
even if the "RUN/STOP" button is pressed.
z To stop the pump, turn the power supply OFF or turn this function
OFF.
