Production protection 

1.

 

Used to adjust the minimum production temperature in cooling mode. If the  set 
temperature is reached, the compressor stops. 

2.

 

Used to set the minimum pressure of the production circuit, under which the alarm is 
triggered. 

3.

 

Used to adjust the anti-freeze protection of the production circuit. If the external 
temperature drops below 5°C, the circulation of the production circuit pumps is 
activated. If the temperature drops below 20°C in any part of the production circuit, 
the heat pump starts up. 

Danger:

  The setting of the minimum production temperature is a very important 

parameter in the start-up of the equipment. A bad configuration of this value can lead to 
serious equipment damage due to freezing. The minimum production temperature must 
be at least 5ºC higher than the freezing temperature of the fluid used. If you are not sure 
of the freezing temperature of the fluid used, check it with a refractometer. 

 

 

Compressor delay 

1.

 

Used to adjust the duration of the compressor switched on delay. 

Note:

 The compressor switched on may experience extra delays due to automatic pre-start 

checks. 

 

 

 

Trial period 

2.

 

Used to enable the trial period. If it is enabled, the heat pump is locked after the 
established time. 

3.

 

Used to adjust the duration of the trial period. 

Note:

 The trial period must be disabled to unlock the heat pump. 

 

 

 

2.14.

 

Probe configuration 

 

 

 
 

 

 

XXXXXX 

1.

 

Display the type of probe installed in each analogue input and their current value. 

2.

 

Used to enter a correction of the probe readings. 

Note:

 There are screens for all temperature and hydraulic pressure probes and for the 

external temperature probe.
