Safety notes
Prevent danger resulting from damaged power
supply cables. If damaged, the power 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 power 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.
• The maximum permissible distance between the digital
controller of the functional unit and the transceiver
is 16.4 ft.
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 plant at a flow pressure
of 0.3 MPa (45 psi) on both sides.

• Test pressure
If static pressure exceeds 0.5 MPa (72.5 psi) a pressure-
reducing valve must be fitted.
Avoid major pressure differences between hot and cold water
supply.
