5.17 Warming up function
5.17.1 Warming up function
During winter or night, this function operates pump automatically to heat the
circulating fluid by the pump’s heat radiation to keep the circulating fluid
temperature around the warming up temperature setting while the product’s
operation is stopping. If it is necessary to shorten the circulating fluid
temperature rising time when starting the operation, set this function in
advance.
●
The pump operates until the circulating fluid temperature b2
℃
of the
warning up temperature setting.
●
When the circulating fluid temperature b2
℃
of the warming up
temperature setting, the pump stops automatically.
●
When the circulating fluid temperature becomes -2
℃
of the warming up
temperature setting, the pump operates automatically again.
If the warming up function is set, [RUN] lamp repeats to be lit on for 0.5 sec
and off for 3sec. during standing by (When the pump does not operate). The
[RUN] lamp blinks every 0.3sec. during the automatic operation of the pump.
The default setting of this function is “OFF”.
While the warming up function is “ON”, the warming up function will be
prioritized higher than the anti-freezing function (refer to “5.17Warming up
function”) and anti-freezing function does not start.
The power supply should be ON for this function. Otherwise this
function cannot start.

This function can be used only while the power supply is ON and
the operation is stopping.
z
Fully open the valve or manual bypass valve arranged by the
customer so that the circulating fluid can circulate when the pump
starts automatic operation.
z
In extremely cold weather conditions, the heat generated by the
pump may not be enough to raise the circulating fluid temperature.
z
During the automatic operation, the pump does not stop even if you
press "RUN/STOP" key. To stop the pump, shut off the power or
make this function “OFF”.
z
This function cannot prevent the freezing of the auto-fluid fill circuit.
Make prevention against the freezing for this by customer.
