4.2 Electric connections

• The single-phase electrical supply (230V-50Hz) of the exchanger must come from a protection and
switching device (not supplied) complying with the standards and regulations in force in the country
where it is installed (in France, refer to standard NF C 15100).
• use the supply cable delivered with the appliance: 2 poles + Earth 10/16 A in 3G1 (section 1 mm²).
Do not admit any long extension or multisocket connection.
Remark: Plan for a socket to connect the supply cable delivered with the appliance.
• Electrical protection: this current socket must have a 5 A fuse switch with, upstream, a 30 mA
differential circuit breaker (calibre > than 5 A), or an independent 30 mA circuit breaker (calibre 5 A)
upstream.
• use a 3G1 wire (1 mm² section) if you wish to control a complementary pump (fig. 1), an electric
valve (fig. 2 and 3) or a boiler (fig. 4) to provide power to the primary circuit of the exchanger. This
function is carried out via the dry contact without polarity "normally open at rest" (Imax 5A at 250 Vac
50-60hZ) available on the regulator terminals 19-20.
C: complementary pump
CH: existing boiler
F: fuse
The elements: C - CH - F - KA1 - V' - V'' are not supplied with this device.
Notice:
• electric cables shall be fixed,
• the wire connected to terminals 19-20 must go through the additional discharger 'grommet' (supplied) which
should be installed on the base of the box.
