User manual ALFA 30

Thermometer.

VDH doc. 931376 Version: v1.1 Date: 18-08-1995

Software: ALFA 30 File: DO931376.WP8 Range: -50/+50°C per 1°C

*Installation.

On the topside of the ALFA 30 you can see how the sensor, power supply and relay has to be

connected.

After connecting the ALFA 30 to the power supply, a self test function is started. As this test is

finished the measured temperature appears in the display.

*Control.

The ALFA 30 thermostat has for normal use no need for controls. Only for adjustment of the

sensor the ALFA 30 has three hidden pushbuttons on the front. These key are:

SET - view / change the setpoint.

UP - increase the setpoint.

DOWN - decrease the setpoint.

These pushbuttons are placed at the following places at the front:

SET - To the lower right of the display.

UP - To the upper left of the display.

DOWN - To the lower left of the display.

*Setting internal parameter.

To adjust the sensor-offset use the following instructions;

By pushing the DOWN key more than 10 seconds, you enter the ‘internal programming menu’. In

the left display the upper and lower segments are blinking. Over the UP and DOWN keys the

required parameter can be selected (see table for the parameters). In this case only ‘04’ offset

temperature sensor.

If the required parameter is selected, the value can be read-out by pushing the SET key. Pushing

the UP and DOWN keys together with the SET key allows you to change the value of this

parameter.

If after 20 seconds no key is pushed, the ALFA 30 changes to its normal operation mode.

*Adjustment sensor.

The sensor can be adjusted by using the Sensor Offset (parameter 04). Indicates the ALFA 30

e.g. 2°C too much, the Sensor Offset has to be decreased by 2°C.

*Error messages.

In the display of the ALFA 30 the following error messages can appear:

Er - Sensor broken Solution:

- Check if the sensor is connected correctly.

- Check the sensor (1000Ω/25°C).

- Replace the sensor.

EE - Settings are lost. Solution:
