* Description.

The ALFANET 95 is a cooling/heating thermostat with various automatic defrost and fan drive facilities.
It can be programmed through the ALFANET PC-INTERFACE on the PC.

* Installation.

On the connection diagram of the ALFANET 95 is shown how the sensor, power supply and relays
should be connected. After the ALFANET 95 has been connected to the power supply a self-test
function will take place, after which the measured temperature will appear in the display.

* Operation.

The ALFANET 95 thermostat can be operated by means of four pushbuttons on the front. These
pushbuttons are:
SET - view / change the set point.
UP - raise the set point.
DOWN - lower the set point.
 C - hidden key under the  C text.

* Normal operation status.

During normal operation the temperature of the control sensor is shown in the display.

* Viewing the set point.

By pressing the SET key the set point becomes visible. At the same time the decimal point of the right-
hand display will blink, as an indication that the set point is being read. A few seconds after the SET
key has been released, the set point will disappear and the measured value will be visible again.
