If the measured temperature differences are higher than the adjusted switch-on temperature differences, the pump (R1) will be activated a ...

The display is permanently off. Press button ➄. Display illuminated? no yes Controller has been in standby, everything o.k. Check the supply line and recon- nect it. The fuse of the controller could be blown. The fuse holder (which holds the spare fuse) becomes ac- cessible when the cover is removed. The fuse can then be replaced. Check the power supply of the controller. Is it disconnected? no yes Disconnected temperature sensors can be checked with an ohmmeter. Please check if the resis ...

The controller calculates the temperature difference between collector sensor S1 and tank sensor S2. If the difference is larger than or identical to the adjusted switch-on temperature difference, the pump (R1) will be switched on and the tank will be loaded until the switch-off temperature difference or the maximum tank temperature is reached.

Sensor Sensor Sensor Valve Tank Tank heat exchanger Tank 3 Tank 2 or backup heating Upper tank sensor System screen in the system monitoring display The system selected is indicated in the system monitoring display. It consists of several system component symbols which are – depending on the current status of the system – either flashing, permanently shown or “hidden”. Collectors with collector sensor 3-port valves Only the flow direction or current switching position are indicated. Tanks 1, 2 and 3 with he ...

3. Time: Î Adjust the clock time. First of all adjust the hours, then the minutes. 2. Unit: Î Adjust the desired unit. 4. Date: Î Adjust the date. First of all adjust the year, then the month and then the day. 5. System: Î Adjust the desired system. Note If the desired system layout has been selected in the ARR channel, the ROSA channel can be skipped. 6. ROSA: Î Enter the 4-digit number given by the RESOL Online Service Assistant. 5 Initial commissioning When the hydronic system is fi lled and ready for operation, connect the cont ...
