Ad Temperature alarm delay
A4 Digital input n.1 configuration
A5 Digital input n.2 configuration
A6 Cut-out of compressor by external alarm:
0=OFF,100=ON. Enabled if either A4 or A5 is 1 or 2.

between ambient temp. and evaporator temperature
2=controlled by a thermostat according to the evaporator
temperature
F1 Fans ON Set-Point: F0=1 fans activated if evap. T. <
(ambient T - F1-A0) and OFF if evap. T. > (ambient T. - F1)
F0=2 fans ON if evap. T. < (F1-A0); and OFF with evap. T. > F1
F2 Stop fans when compressor is Off (0=no,1=yes). Active if F0=0 C
F3 Stop fans during defrost (0=no,1=yes).
Active for any value of F0
Fd Stop after dripping. Active for any value of F0
H OTHER SETTINGS
H0 Address within network
H1 Selection of relay 4 functioning:
0=auxiliary output

2. for the set times to become operative, the instrument must be swtiched OFF and ON again.
3. on MTCA models the following values have to be assigned to the next parameters:
- r3: must be 0
- d0: 2 or 3 (default: d0= 2)
- dt: irrilevant
- dI: 0.
