Setting internal parameters
Next to the adjustment of the setpoint, internal settings can be made like differential, sensor offset,
setpoint range and the functions of the thermostat.
Push the DOWN key for more than 10 seconds, to enter the 'Internal Programming Menu'. In the left
display the upper- and lower-segment are blinking. With the UP and DOWN keys the required
parameter can be selected (see the parameter table).
If the required parameter is selected, the value can be read-out by pushing the SET key. Pushing the
UP or DOWN key to change the value of this parameter.
If after 20 seconds no key is pushed, the ALFANET 72 changes to the normal operation mode.
