6.2.2 - MODULE CC1 CONFIGURATION
• The communication and control module manage the circulator and
the communication interface between the system and the generator.
It is equipped with 2 micro-switches, No. 1 and No. 2.
Micro-switch No. 1 :
In “ ON ” position, the circulator starts automatically if the outdoor
temperature is below 0°C to prevent the hydraulic circuit from
freezing. This position is recommended if the outdoor module is
installed in a location exposed to freezing temperatures (not
recommended).
The factory default setting for this micro-switch is “ OFF ”.
Micro-switch No. 2 :
Must be set to “ ON ” (activates the water flow safety on the
system).
6.2.3 - SYSTEM PARAMETERISATION
• Make sure that the control unit selector is “ OFF ”.
• Check the parameterisation and adapt it accordingly based on the
type of installation.
The parameters are set on the control box (refer to the system's installation manual).
6.3 - ADDITIONAL HYDRAULIC CIRCUIT VERIFICATIONS
6.3.1 - FORCED CIRCULATOR OPERATION
• In order to conduct the final verifications of the hydraulic circuit, force
the pump to start as follows (installation power ON):
- Set the system control unit to “ OFF ”.
- Press and hold the button for 5 seconds.
The circulator starts.
The circulator indicator light flashes.
- Check that the “ H
2
O ” flow indicator is illuminated.
6.3.2 - VERIFICATIONS
• Purging of circuits.
• Hydraulic pressure (2 bar).
• Water flowrate: the unit is equipped with 1/4 SAE pressure taps at the circulator inlet and outlet (see paragraph 2.1.1),
so that the pressure loss can be measured using a hydraulic pressure gauge. Use the circulator curves below to
determine the water flow rate.
In order for the apparatus to work properly, the nominal flow rate must be respected.
