Configuration of alarm relay
The alarm relay will be activated upon an alarm signal from the following groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input is activated for alarm
16 - Defrost alarms
32 - Miscellaneous
The groups that are to activate the alarm relay must be set by using a numerical
value which is the sum of the groups that must be activated.
(E.g. a value of 5 will activate all high temperature alarms and all sensor errors).

*) Can only be set when regulation is stopped (r12=0)
**) Can be controlled manually, but only when r12=-1
***) With access code 2 the access to these menus will be limited
Forced control
If you need to force-control an output, you should set r12 to -1 (manual
mode). You should then select the relevant relay function, e.g. u58. Go to the
function by pressing the middle button. Select On.

Factory setting
If you need to return to the factory-set values, it can be done in this way:
- Cut out the supply voltage to the controller
- Keep upper and lower button depressed at the same time as you recon-
nect the supply voltage
Factory settings are indicated for standard units. Other code numbers
have customized settings.
