3 | © RESOL 06277 TLR2.mon.en.indd 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. Technical data Housing: plastic, PC-ABS and PMMA Protection type: IP 20 / DIN 40050 Ambient temperature: 0 ... 40 °C Size: 172 x 110 x 46 mm Power supply: 220 … 240 V~ breaking capacity: 1 relay output (alternating relay) Schaltstrom 4(1) A Ambient temperature: -20 °C ... bis +40 °C store nominal temperature: 20 ... 90°C Display: LCD, multi functioning combi display with pictogramms, two 2-digit description field and two 4-digit 7-segment-displays as well a 2-coloured LED. Installation: wall mounting, control panel-Instal- lation possible Operation: vie 3 pushbuttons in the front of the housing Inputs: 2 temperature sensors Pt1000 Degree of pollution: 2 Rating surge voltage: 2,5 kV Temp. for ball pressure check: 75 °C 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.

| 4 © RESOL 06277 TLR2.mon.en.indd 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.

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

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 backwards forward Set (selection / setting mode) 3.2 controlparameter and display channels • SU Upper Store temperature display channel of the current upper store temperature • SL Lower Store temperature display channel of the current lower store temperature • HO Hours of Operation display channel of the operation hours • TO Temperature On setting channel switch-on temperature • TF Temperature ofF setting channel switch-off temperature • MM Manual Mode setting channel manuel mode • PG ProGramm display channel programme number • VN Version Number Anzeigekanal Versionsnummer 3.3 display channel SU SU shown the current upper store tempertaure 3.4 display channel SL SL shows the current lower store temperature 3.5 display channel HO HO shows the operation hours if the controller 3.6 display channel PG PG shows the programme number of the controller 3.7 display channel VN VN shows the version-number of the controller software 2.3 example of use

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“. manual ope- ration 0 = on 1 = off 2= Auto MM: switch-off temperature setting range 0, 1, 2 factory setting 2 (Auto) constantly green: relay/pump switched on constantly red: relay/pump switched off flashing green/red: initialisation defective sensor manual operation 3.11 status-LED blinking codes

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. resistance values of the Pt1000-sensors fuse T4A Your specialist dealer: Note The design and the specification can be changed without any prior notice.
