1.29 KITS AVAILABLE ON REQUEST.
• 2 zone kit (1 direct and 1 mixed). Should it be
necessary, you can install the zone kit, which
allows you to divide the heating system into
two separate zones - one direct and one mixed.
• Configurable relay interface kit The module
is set up for a relay board, which amplifies the
appliance features and, thus, the operating
possibilities.
• 2-relay board kit. The hydronic module can
manage up to two dehumidifiers. A 2 relay
board that manages dehumidifier enabling is
available to pair the appliances.
• R410A circuit connection kit. For R410A
circuit wall connections, there is a kit with the
two pipes necessary to create the circuit.
Kits are supplied complete with instructions for
their assembly and use.
