About the wait function
When the wait function is set to [
ON
],
the mode will remain “waiting” without counting down the time
until temperature in the chamber (indication) will be within the wait deviation range between -3
℃
and +6
℃
to the set temperature. When you set the set time to 0 minute, the unit will operate from
the “Start temperature” to the “Set temperature” at full power.
When you have set time longer than the specified performance, the unit will control heating and
cooling so that the set temperature will be attained at the set time.
Even when the indicated temperature drops while temperature is stable due to opening of the door,
the mode will remain “waiting” without counting down the time if the wait width upper or lower limit
is exceeded.
When you set the wait function to [
OFF
], the unit will proceed to the next step at the set time
irrespective whether the temperature is within the wait width deviation between the set temperature
and the indicated temperature.
When the set time is set to a short time exceeding the heating and cooling capacity, the unit will
proceed to the next step before the set temperature is attained and you need to make sure that the
wait function is set at [
ON
] when you are going to operate at the full power.
