3.5.1 - Recommendations for connecting the
system to the power supply
3.5.2 - Connecting the Pilot to the power
supply
N.B: See electrical diagram in the appendix.
Check:
• The input current
• The number and thickness of power cables
• Fuse or circuit breaker ratings
The power supply must come from an electrical protection
and sectioning device which complies with all current rules
and regulations. This CE-stamped appliance complies with the
essential requirements of the following directives:
- Low voltage n°2006/95/CE
- EMC n° 2004/108/CE
Check the the installation is equipped with a correctly sized and
connected ground cable.
Check that the voltage and frequency of the general power
supply  t requirements. The amount of variation in voltage
permitted is:
230 V -10% à +6% 50Hz for single phase models + ground cable
400 V -10% à +6% 50Hz for three-phase models + neutral + earth
cable.
The Pilot must be protected beforehand by an
all-pole circuit
breaker
(minimal distance to separate contacts = 3mm: EN 60
335-1) using either fuses or a thermal magnetic circuit breaker
calibrated to the right power for the Pilot.

Pilot is set for 400Vthree-phase
use.
For 230V single phase use, you will need to  t a
bridge (supplied in a small package) between the
three phase terminals. See diagram below.
Make sure the bridge is properly pushed
into place. See below:
PH-N : Phase/Neutral 230V single phase - 50Hz power supply
CPAC : Heat Pump circulator pump, pre-connected
Cchauf 1 : Circulator pump for heating circuit1

Cchauf2 : Circulator pump for heating circuit 2
ou ECS Primary circulator pump for domestic water circuit
LTP1/LTP2 : Temperature-limiting safety aquastat (65°C) with manual reset. It must be
placed at the start of the under oor heating circuit (not supplied).
