Safety notes
Avoid danger due to damaged power supply cables.
In the case of damage, 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 socket power supply is only suitable for indoor use.
• The functional unit and plug-in connectors must not be
directly or indirectly sprayed with water when cleaning.
• The voltage supply must be separately switchable.
Applications
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 45 psi on both sides.
Specifications
• Flow pressure
- Minimum flow pressure without downstream
resistances: 7.25 psi
- Minimum flow pressure with downstream
resistances: 14.5 psi
- recommended 14.5 - 72.5 psi
- greater than 72.5 psi, fit pressure
reducing valve
• Max. operating pressure 145 psi
• Test pressure 232 psi
• Flow rate at 45 psi flow pressure
(with simultaneous use of all outlets): approx. 14.5 gpm
• Minimum flow rate: 1.3 gpm
• Temperature
- max. (hot water inlet) 176 °F
• Hot water temperature at supply connection min. 4 °F higher
than mixed water temperature.
• Voltage supply: 120 V AC, 50/60 Hz
(socket power supply 120 V AC/6 V DC)
• Type of protection: - Function unit IP 40
- Socket power supply IP 40
• Water connection cold - RH
hot - LH
Note
Major pressure differences between hot and cold water supply
should be avoided.
Electrical test data
• Software class: B
• Contamination class: 2
• Rated surge voltage: 2500 V
• Temperature for ball impact test: 212 °F
The test for electromagnetic compatibility (interference
emission test) was performed at the rated voltage and rated
current.
Electrical installation
Electrical installation work must only be
performed by a qualified electrician. This
work must be carried out in accordance with
the regulations according to IEC 364-7-701-1984
(corresponding to VDE 0100 Part 701) as well
as all national and local regulations.
Always switch off the power supply
before making electrical connections.
New installation
During installation, please note:
• The lid of the function unit must be removable to permit
maintenance work.
• The function unit must not be installed with the lid facing
downwards.
Prepare the wall for the installation, refer to the dimensional
drawing on fold-out page I.
Install function unit, see fold-out page II, figs. [1] to [9].
Observe printing on the lid.
1. Prepare holes for the function unit as well as slots for
the pipes and vacant tubes, see fold-out page II, figs. [1]
to [4].
2. The vacant tube (6m) provided must be used when
connecting the function unit to the faucet and the plug
power supply.
3. Unscrew screws and remove lid, see fig. [5].
4. Align and fasten function unit in place, see fig. [6].
Do not solder the connections.
