Safety notes
Prevent danger resulting from damaged voltage supply cables.
If damaged, the voltage supply cable must be replaced by the
manufacturer or his customer service department or an equally
qualified person.
• Installation is only possible in frost-free rooms.
• The optional voltage supply unit is only suitable for indoor use.
• The plug-in connectors must not be directly or indirectly sprayed with
water when cleaning.
• The voltage supply must be separately switchable.
• Use only genuine replacement parts and accessories. The use of
other parts will result in voiding of the warranty and the CE identification,
and could lead to injuries.
Application
Thermostatic mixers are designed for hot water supplies from pressurised
storage heaters and offer the highest temperature accuracy when used in
this way. With sufficient power output (from 18 kW or 250 kcal/min),
electric or gas instantaneous heaters are also suitable.
Thermostats cannot be used in connection with unpressurised storage
heaters.
All thermostats are adjusted in the factory at a flow pressure of 0.3 MPa
on both sides.
Operating conditions
The maximum permissible distance between the digital controller/diverter
of the functional unit and the transceiver is 5 m. The best wireless
reception is achieved when the transceiver is surface-mounted.
Sources of interferences
The transceiver operates in the ISM-frequency range (2.4GHz). The
installation in the vicinity of equipment with the same channel occupancy
(eg wireless devices, RF components, etc. [observe the manufacturer´s
documentation!]) should be avoided.
Obstructions/barriers
For operation under adverse environments, in buildings / rooms with
reinforced concrete walls, steel and iron frame, or near of obstructions
(eg furniture) of metal, the radio reception can be disturbed and
interrupted.
Kind of obstructions
Wood, synthetic material
Water, brick, marble
Plaster, concrete, glass, solid wood
Metal
