thermostat parameters are not fixed and can be modified.

The default, limit and step values for the thermostat parameters are
shown in 

"Annex I" on page 25

.

Defining and activating the control mode

The unit is equipped with a thermostat which controls the cooling or
heating capacity of the unit. Select the appropriate mode:

/

21

/

22

  (capacity step in manual mode): OFF or ON of

compressors 11/12/21/22.

F1*

F2*

 (air flow in manual mode): off, low, medium or high of

circuit 1/2.

INL WATER

:  inlet control mode: uses the entering water

temperature to control the capacity of the unit.

OUTL WATER

:  outlet control mode: uses the leaving water

temperature to control the capacity of the unit.
