TRL2
Electronic store charge controller, with LCD combidis-
play for concurrent display of the upper and the lower
store temperature for optimised charge with one ener-
gy source (e.g. central heating boiler). The temperature
is collected by temperature sensors in the upper and
lower part of the store. When the switch-on tempe-
rature of the upper sensor is under-run, the store is
charged until the switch-off temperature is reached in
the upper sensor. The controller is menu-driven.
Two sensors from our product range (type Pt1000) are
needed, (please order additionally) e.g. 2 x FRP150.

The store charge controller RESOL TLR2 optimises the
charging of a warm water- heat accumulator via one energy
source, e.g. a central heating boiler. The store temprature
is collected by sensors S1 and S2 in the upper resp. lower
part of the store. The charging cycle starts as soon as the
upper sensor S1 collects a temperature thatis lower than
the preadjusted switch-on temperature. The charging occurs
until the temperature of S2 (in the lower part of the store)
exceeds the preadjusted switch-off temperature.
Benefits:
Functioning - The store is heated up completely (avoidance of danger
caused by Legionellen).
- The heating up of the store takes place in big intervals ;
therefore longer burner running time
The controller TLR2 needs two sensors from our product
range.

For the controller RESOL TLR2 precision temperature
sensors in Pt1000-version (FKP and FRP) are used.
FK: 1,5 m long weather- and temperatureproof siliconcable
for temperatures from -50 °C ... +180 °C, preferably for the
collector.
FR: 2,5 m long PVC-cable for temperatures from -
5 °C ... +80 °C, preferably for the store.
The corresponding local VDE-regualtions must be obeyed.
The sensor cables carry low voltage and musn’t be installed
in one cable channel with cable that carry more than 50V.
The sensor cables can be elongated up to 100 m, whereas
the cross-section of the extensioncable must have 1,5 mm2
(resp. 0,75 mm2 at cable lengths up 50 m). With long cables
and when using cable channels cables with twisted leads
should be used. For immersion sensors immersion sleeves
must be used.
1. Sensor types
immersion sensor: available in different lengths (immer-
sion depth)
FK...60: 60 mm immersion depth, brass sleeve, chromium-
plated
FK...150: 150 mm immersion depth, brass sleeve, chromium-
plated
Important: push the sensor completely into the sleeve and
tighten the fitting.
Pipe sensor: for any pipe diameter, complete with clam-
ping band
FK...21 or FR...21
Der Sensor must have good thermal contact to the pipe.
Therefore clean the contact surface carefully and apply heat
conduction paste between sensor and pipe. For protection
against outside temperature influences wind the sensor cable
around the pipe once and insulate well.
Contact sensor: for application to plane surfaces
FK...9 or FR...9
Pay attention to good thermal contact. Use heat conduction
paste and insulate against outside temperature influences.
FK... : collector sensor
FR... : reference sensor (store sensor)

2.1 mounting
The mounting has to be made only in dry interiors. Keep in
mind that the controller musn’t be installed at a place where
it can be influenced by strong electromagnetic fields. Accor-
ding to the current regulations for installation the controller
must be equipped with an additional set-up which allows the
separation from the power line by an isolating distance of at
least 3 mm. Attend to separated laying when installing the
mains connection cable and the sensor cable.
1. Unscrew the cross-head screw of the blind and pull the
blind down from the housing.
2. Mark the upper attachment point on the subsurface and
premount the attached dowel with the matching screw.
3. Replace the housing at the upper attachment point, mark
the lower attchment point at the subsurface (hole centre
distance 130 mm), afterwards fix the lower dowel.
4. Replace housing at the upper point and fix it with a at-
tachment screw.
2. Installation Attention!
2.2 Electrical connection The power supply of the controller must be effected by
an external power switch (last workstep!) and the power
supply must be 220 ... 240 Volt (50...60 Hz). Flexible cables
must be fixed to the housing with the attached strain relief
clamp and the matching screws.
The controller is equipped with 1 relay (change-over con-
tact), to which the matching consumer load is attached (e.g.
store charge pump):
• Pump-relay R1
14 = home contact R
15 = medium contact M
16 = make contact A
The temperature sensors (S1 and S2) are connected to
the following clamps with any polarity:
1 / 2 = sensor for the upper store temperature
3 / 4 = sensor for the lower store temperature
The mains connection is at the clamps:
19 = neutral wire N
20 = conductor L
12 = earthing clip
pipe clamp
fuse
sensor clamps
consumer-clamps
(pump)
bridge
Indication:
The medium contact M (15) and the conductor L’ (18) are
bridged in delivery condition.
After removing the bridge the change-over contact (RMA)
becomes a potential-free relay.
Ensure separation from power
supply before opening the hou-
sing

3 Operation and functions
3.1 setting switch The controller is operated by 3 push-buttons below the dis-
play. The forward-button (1) serves the function of scrolling
forward through the display menu or raising the set values.
The backwards button(2) is serves the contrary.
After the display channels there are the setting channels. In
order to get to these channels, the forward button has to
be pushed for 2 sec. after channel HO. If the display shows a
set value, SEt is shown in the display. In this case the setting
mode can be changed if the set-button (3) is pushed.
 chose channel with button 1 and 2
 press button 3 quickly, display „SEt“ flashes
 set the value with buttons 1 and 2
 press button 3 quickly, display permanently shows„SEt“
again, the setted value is memorised

4. Initiation
First switch on the power supply. The controller initialises
while the operation control lamp flashes green and red.
After finishing the initialisation the controller is in automatic
operation mode which ensures by the factory settings an
optimum degree of efficiency for most systems.
In case that the individual systems require an adaptation to
the controller parameters they can be changed with the
corresponding set values (see 3.2).
3. 8 setting channel TO When the upper store temperature SU falls below the
setted value TO, the controller switches on the relay/pump
and loads the store. The display shows and the status-
LED glows green.
TO:switch-on temperature
setting range 20,0 ... 95,0 °C
in 0,5 steps
factory setting 40,0 °C
3.9 setting channel TF
While the controller charges the store the lower store SL
rises. When this temperature exceeds the value setted in
TF, the relay/pump is switched-off and the loading of the
store stops. The symbol disappears from the display and
the status-LED glows red.
In order to avoid wrong settings the values TO and TF are
blocked against each other.
TF: switch-off temperature
setting range 20,0 ... 95,0 °C
in 0,5 steps
factory setting 45,0 °C
3.10 setting channel MM
Here you can chose between automatic and manual ope-
ration. In the manual operation mode the charging of the
store can be started and stopped manually.
For permanently deactivated store charge chose „0“, for
permanently activated store charging chose „1“. If the con-
troller is to charge the store automatically chose „2“.

5. tips for fault location
PLease check the following if the controller does
not work properly:
1. power supply
In case that the operation control lamp is lapsed please
check the power supply of the controller.
The controller is protected with 1 fuse T4A. You can
exchange it after removing the blind (spare fuse is in the
accessory bag).
2. defecctive sensor
In case that a system fault is caused by a defective sensor the
operation control lamp flashes red/green and the symbol
is shown in the display. A corresponding error code is shown
in the display for the sensors in question.
short-circuit: a short-circuit of the sensorcable with
declaration of the affected sensor is
shown in the display with the error
code -888.8.
wire breakage: Interruption of the sensor cable with
declaration if the affected sensor is
shown in the display with the error
code 888.8.
Pinched off Pt1000-temperature sensors can be checked
with a resitance measuring device and have the resitance
values shown in the table on the left.
