this time the hygrometer should show a humidity of 90 to 95 %. It should now function

properly. It is important to repeat this step every 6 months to ensure the accuracy of

this gadget.

Starting

Make sure you are familiar with the incubator and its controls. After putting the plug

into a 230 voltage safety socket which is according to the regulations, your incubator

is operational.

Temperature

Now you should activate the operating switch. Heating and fan are switched on at the

same time. The heat control light will blink and the heating fan will start to warm up the

incubator.

The coarse potentiometer is used to get the temperature within several degrees of the

required setting. With the ﬁne potentiometer you can reach the exact temperature you

need. The heat control light will blink when the required temperature has been reached.

Due to the blink intervals the need of energy is kept low. The electronic thermostat

pulses on to the adjusted temperature. After long-term pulsing the required tempera-

ture is reached and your incubator now only needs very low energy. Please turn up the

temperature carefully and never switch the regulators on maximum!

If you turn the coarse- or the ﬁne potentiometer down a little bit, the heat control switches

off and the heating is stopped. However, the fan continues to run.

Additionally we installed a security thermostat in all incubators, which prevents over-

heating. For safety reasons, the adjustment has to be done with a thin screw driver:

/10 of a turning is equal to 1 °C. A turn to the right causes an increase of the shut down

temperature, a turn to the left reduces it.

The shutting down of the temperature will be conﬁrmed with a quiet click and the extinc-

tion of the thermo- and the humidity control lights.

It is necessary that the stopper is ﬁxed to its shut down temperature after the test run.

Please turn it very carefully, as a minimum turn already changes the shut down tem-

perature.

When you let the temperature rise with the thermo adjustment you can decide about

the exact shut down temperature. The shut down temperature should be at least 1 °C

above the incubating temperature because the feeler of the protective thermostat sits

next to the heating spiral and feels a higher temperature there than inside the breeding

room.
