COMMISSIONING
Close the main power switch before commissioning the unit.
Refer to the controller instruction manual for the commissioning procedure.
- Close the external interlock
- Push the key “ON” of microprocessor control
- If all the permissive are available, the display will show “UNIT ON”
After the procedure has been completed, the unit will automatically start with a delay of about 5 minutes when
the microprocessor control, flow switch and circulator pump permissives are available.

For control of outlet water temperature, the reference probe must be installed at the exchanger outlet, or in the
case of several exchangers, in the common water outlet after the manifold.
The activation of unit power steps depends on activation and deactivation delays in relation to a dead band.
When the reference water temperature exceeds the set point without leaving the dead band, no outlets are
enabled or disabled to lower the water temperature; when the reference water temperature exceeds the sum of
the set point value and the dead band, a unit power step (e.g. start-up of a compressor or the transition to full
capacity operation of an active compressor) will be activated.
