6.1 - Function
The CLIMATIC™ 60 control the changeover mode (for reversible units only) to specify the appropriate demand on
heat water or chilled water production.
6.2 - Description
The changeover can also be pre-specify according to the scheduling and can take different mode for each
schedule mode (A, B, C, D, and BMS).
The changeover mode can be set by different solutions:
Automatically :
The CLIMATIC™ 60 determines the appropriate production of the water according to the outside temperature and
move automatically the unit from the cooling to heating mode and heating to cooling mode.
If the outside temperature is below the setting value (3225), the unit will operate as a heat pump.
If the outside temperature is over the setting value (3226), the unit will operate as a chiller.
Manually :
The changeover mode is pre-specifyd for each schedule mode. The various modes available are “Cool” mode,
“Heat” mode or “Dead zone”. In this case the outside temperature has not effect on the changeover mode.
Remotely :
The changeover mode is set according to a remote dry contact connect on a free custom digital input. In this case
the unit swaps in cooling or heating mode according to the status of the digital input. Please refer to the paragraph
“Free Input / Output” for more details.
