* 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.
