Operating instructions
Please read and observe the detailed safety instructions at the start
of these instructions!
• Important: The appliance may never be exposed to frost!
CAUTION:
Risk of electric shock!
▶ Switch off the mains voltage supply immediately if a fault occurs.
• Immediately shut off the cold water supply to the appliance should it
leak.
4.1
Your new appliance
This floor-standing water heater enables you to heat up as much drinking
water as required to approximately 60 °C and store it for household use.
On request a qualified professional will increase the maximum
adjustable temperature to approx. 80 °C.
Several tap connections can be supplied with hot-water. The mixers can
always supply cold-water.
Our products are environment-friendly, can be recycled and conserve
energy.
How to operate the floor-standing water heater (Fig. 8)
• Adjustments are facilitated by the control panel on the appliance.
The control panel indicates the various settings, temperatures,
volumes of water and how many baths or showers may be taken.
• Preselect the required temperature with temperature selector
switch 1.
4.2
Position
•
Cold and anti-freezing protection
I
The water is heated to approx. 38 °C.
E
Energy conservation position. The water is heated to approx.
60 °C.
The selector switch will click into place at position "E".
III
Setting for hot-water and when large amounts of hotwater are
required. The water is heated to approx. 80 °C. (this setting only
by qualified professional)
• During the heating process, expansion water drips out of the safety
valve.
• Rotate the temperature selector switch 1 to position "•" to switch off
the heating.
4.3
Operation during the off-peak period
(off‑peak power)
This is the most cost-effective mode of operation.
Set the required water temperature with the temperature selector
switch 1.
• The power supply company activates off-peak power by means of
a signal in the power system. Primary heating then switches on
automatically.
You will then have hot-water during the day.
4.4
Additional operation during the peak period
If the volume of hot-water provided during the night is insufficient, water
can also be heated during the peak period:
• Press push-button 2.
The water is heated to the temperature set on the temperature selector
switch 1. When the selected temperature has been reached, the peak-
rate heating automatically switches off.
TR2000TF – 6 720 875 992 (2025/03)
• Set a higher temperature with the temperature selector switch 1 if
you frequently need to reheat water during the peak period.
As a result, you will have a larger volume of mixed water.
• Rotate the temperature selector switch 1 to position "•" if the floor-
standing water heater will not be heated for a prolonged period.
This setting protects the appliance from freezing.
This does not apply to the fittings and pipes in the cold-water inlet!
4.5
Checking the safety valve
During the heating process, expansion water must drip out of the safety
valve outlet 3.
For reasons of safety the outlet must not be blocked.
• Check that the safety valve is functioning properly at least once
a month.
• Rotate ventilation screw 4 until the valve opens and a powerful jet of
water comes out of the outlet 3.
• Close the valve again with the ventilation screw.
• If the safety valve does not function as described, rotate the
temperature selector switch to position "•" and contact a qualified
professional.
4.6
Saving energy
The appliance operates particularly economically at low temperatures.
Therefore, only set the temperature which you require.
The floor-standing water heater operates most economically in position
"E" (approx. 60 °C), even when large amounts of hot-water are
required. At higher water temperatures, the appliance calcifies at an
increased rate, resulting in greater heat losses!
4.7
Decalcifying
• Inspect the fittings regularly for lime scale deposits and descale with
commercially available descaling agents.
• Actuate the safety valve regularly to remove the lime scale (see
"Checking the safety valve").
The level of lime scale deposited from the water is increased or reduced
at higher temperatures depending on the local water quality (hardness
level I/II/III; soft, medium or hard). It is deposited on the interior of the
water tank and on the heating element as boiler scale and influences the
performance leading to longer heating up time and service life of the
appliance.
The appliance must therefore be checked and decalcified regularly by
a qualified professional. Check also the taps/valves regularly. You can
remove limescale deposits at the tap outlets using commercially
available descaling agents.
Please schedule your first and/or next maintenance visit (inspection of
the protection anode and descaling) with your qualified specialist.
Maintenance work may only be carried out by a qualified
professional. Improper repairs may put the user in extreme danger.
Never use abrasive or corrosive cleaning agents during heating element
or tank interior cleaning.
4.8
Cleaning
• Simply wipe the appliance with a damp cloth. Do not use acidic or
abrasive cleaning materials.
4.9
Customer Service
• In the event of a malfunction, unplug the appliance from the power
supply (pull out the fuse or activate the circuit breaker) and contact
customer service.
Details can be obtained from a customer service centre regarding your
nearest customer service centre or authorised repair shop.
