5.11 Anti-freezing function
5.11.1 Anti-freezing function
This function prevents freezing of the circulating fluid while the product
stops operation in the winter season with heat generated by automatically
operating the pump.
When there is a possibility of the circulating fluid freezing due to changes in
the installation or operating environment (e.g. season, weather), set this
function ON in advance.
z
If the circulating fluid temperature falls down to 3
o
C or less
, the
pump starts operation automatically.
z Heat generated by the pump operation warms up the circulating
fluid.
When the circulating fluid temperature reaches 5
o
C
or higher, the
pump stops operation automatically.
z Repeated automatic operation start and stop of the pump
maintains the circulating fluid temperature to 3
o
C to 3
o
C to prevent
the circulating fluid from being frozen.
When the anti-freezing function is set ON, the [RUN] light blinks every 2
seconds while the pump is in the standby state (while the pump stops
operation). The [RUN] light blinks every 0.3 seconds during the automatic
operation of the pump. The default setting of this function is “OFF”.
This function does not prevent the automatic water fill circuit from being
frozen. Countermeasures against freezing of the automatic water fill circuit
should be taken with the user's equipment.
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. (See “5.17 Warming up function”)
Keep the power supply ON for this function. This function does not
start when the power is OFF.
