EMPERATURE TO ENABLE THE SECOND HEATER
In order to set the temperature to enable the second heater you have to enter the configuration menu (see
paragraph
), enter the
t5h
), and then select the desired value and save the new
value by the OK key.
The temperature to enable the second heater can be used to improve the temperature control, using both
the outputs (K1 and K2) when the setpoint temperature is higher than the “temperature to enable the second
heater”, then allowing to take advantage of all the oven power.
The regulator behaves in the following way:
When the setpoint
temperature is higher than the “temperature to enable the second heater”, both
the outputs (K1 and K2) to set the temperature are always used.
Therefore, starting both the outputs when the oven temperature is lower than the “
setpoint
– lower
hysteresis
” temperature and deactivating both the outputs when the oven temperature is higher
than the “
se higher hysteresis
” temperature.
When the setpoint temperature is lower or equal to the “temperature to enable the second heater” re-
fer to the control area (see paragraph
In order to
deactivate
the “temperature to enable the second heater” you just have to set it to zero (in this
way you also deactivate the control area), while, in order to keep it always ON, you have to set the full scale
value of the thermoregulator and, in this way, you will enable only the control area.
Please note
:
The temperature to enable the second heater can be set only after the On/Off temperature set-
ting has been enabled (see paragraph
