1. Sensor types
Precision-platin sensors type PT1000 (FKP and FRP) are
used for TT1
The arrangement of the sensors is of great importance to
the total efficiency of the regulator. The collector temperature should be measured in the upper part of the collector.
In stores with integral heat exchanger, the sensor must be
directly mounted in the upper part of the heat exchanger.
When using external heat exchangers, the sensor must be
fixed at the bottom of the store. For individual operation
systems, our product range contains 3 different types of
sensors (sensors for installation in existing immersion sleeves, flatscrew sensors or cylindrical clip-on sensors). The
sensor types FK and FR have the same electrical features
and are available in the same models, They only differ in the
connecting cable:
Immersion sensors: in different lengths (immersion
depth) available
FK...60: 60 mm immersion depth, immersion sleeves of
chromium-plated brass
FK...150: 150 mm immersion depth, immersion sleeve of
chromium-plated copper
Important: The sensors must be completely pushed into
the sleeve and the nut must be slightly tightenend.
Cylindrical clip-on sensors: for any pipe diameter; cpl.
with fastening collar; FK...21 or FR...21
Ensure good thermal contact of the sensor with the pipe
work by cleaning the contact area and by applying heat conduction paste between sensor and pipe. In order to protect
the sensor cable against outside temperature influences, it
is recommended to insulate the pipe..
Flatscrew sensors: for installation on flat surfaces
FK...9 or FR...9
Ensure good thermal contact. Use conduction paste and insulate the sensors against outside temperature influences.
Indication:
In order to avoid overvoltage damage at the collector (e.g.
by lightening), it is highly recommendend to use the overvoltage protection RESOL SP1.
FK... : collector sensor
FR... : reference sensor (store sensor)
FK: 1,5 m weather- and temperature resistant silicone cable
for temperatures between -50 °C ... +180 °C, mostly used
for collectors.
FR: 2,5 m P VC cable f or tempe rtu re s betwe en
-5 °C ... +80 °C, mostly used for stores.
Make sure that all electrical works are carried out according
to the relevant local and IEE-regulations. The sensor cables
carry low voltages and they must not run together in a
cable conduit with cables carrying higher voltages than 50
Volts. When using longer cables or cable conduits, please use
screened cables. The sensor cables can be lengthened up to
100 m, but the cross section must be 1,5 mm² (or 0,75 mm²
up to a cable length of 50m); screened cables should be used
preferably. The sensors must not be in direct contact with
water, please always use immersion sleeves.

The unit must only be located internally. It is not suitable
for installation in hazardous locations and should not be
sited near to any electromagnetic field. The controller must
additionally be equipped with an all-polar gap of at least 3 mm
or with a gap according to the valid installaton regulations,
e.g. LS-switches or fuses. Please pay attention to a separate
laying of the cable lines and installation of ac power supply.
1. Unscrew the cross-recessed screw of the cover and
remove it from the housing.
2. Mark the upper fastening point on the underground and
premount the enclosed dowel and screw.
3. Hang up the housing at the upper fastening point and mark
the lower fastening point on the underground (hole pitch
130 mm), afterwards put the lower dowel.
4. Fasten the housing at the underground.
Warning!
Switch-off power supply before
opening the housing.

2. Installation
2.2 Electrical connection
The power supply to the controller must only be made by
an external power supply switch (last step of installation!)
and the line voltage must be 220 ... 240 Volt (50...60 Hz).
Flexible lines are to be fixed at the housing by enclosed
strain relief supports and screws.
The controller is equipped with 1 standard relays, to
which the consumers can be connected:
14 = normally closed contact R
15 = middle contact M
16 = normally open contact A
13 = ground clamp
The temperature sensors (S1) will be connected to the
following terminals independently of the polarity:
1 / 2 = sensor for heat source / heat sink
The power supply is effected to the clamps::
19 = neutral conductor N
20 = conductor L
12 = ground clamp
net clamps
sensor clamps
consumer clamps
Notice:
The middle contact M (15) and the conductor L (18) are
bridged from factory.
After removal of the bridge the changeover contact (RMA)
becomes a potential-free relais.

3 Operation and function
3.1 Pushbuttons for adjustment
The controller is operated by 3 pushbuttons below the
display. The forward-key (1) is used for scrolling forward
through the indication menu or to increase the adjustment
values. The backwards-key (2) is accordingly used for the
reverse function.
The adjustment channels follow the pure indication channels
in the display. In order to come to these channels, press the
forward key to channel HO for 2 sec. If an adjustment
value is shown on the display, SEt is indicated. In this case
you can press the key „Set“ (3) in order to change into
input mode.
Select a channel by keys 1 and 2
Shortly press key 3, so that „SEt“ flashes
Adjust the value by keys 1 and 2
Shortly press key 3, so that „SEt“ permanently appears,
the adjusted value is now saved

5. Tips for fault location
Please check the following points if the controller
does not work faultlessly:
1. Power supply
If the operating control lamp is off, please check the power
supply of the controller.
The controller is protected by one can fuse T4 A, which is
situated at the base/isolation plate and can be replaced by
opening the cover of the housing (spare fuse is enclosed in
one of the accessory bags).
2. Sensor failure
If there is a malfunction due to a sensor defect, the operating control lamp flashes red and the symbol is shown
on the display. An error code for the concerned sensor is
shown on the display.
Short-circuit: Short-circuit in the sensor wire with
indication of the concerned tem pe rature
sensor(TT). The error code -888.8 is
shown on the display.
Line-break: Interruption of the sensor wire with
indication of the concerned temperature sensor (TT). The error code 888.8 is
shown on the display.
Clamped Pt1000-temperature sensors can be checked by
a resistance-measuring device. The measured temperatures
can be compared with the resistance values of the table
opposite.

PT1000 sensors

4. Commisioning
Ac power supply must be activated. The controller passes
an initialisation phase in which the operating control lamp
flashes red and green.
If individual conditions require an adaptation of the parameter, please adjust the values accordingly (vgl. 3.3).
