The controller is equipped with the RESOL VBus® for data transfer with and energy supply to external modules. Carry out the connection at the two terminals marked “VBus” (any polarity). One or more RESOL VBus® modules can be connected via this data bus, such as:

• RESOL GA3 Large Display from version 1.21

• RESOL SD3 Smart Display from version 1.21

• RESOL DL2 Datalogger

• RESOL VBus

/ USB interface adapter

Connecting the device to the power supply must always be the last step of the installation!

The controller is supplied with power via a power supply line. The power supply of the device must be 100 ... 240 V~ (50 ... 60 Hz) .

The controller is equipped with a change-over relay to which a load such as a pump, a valve, etc. can be connected:

10 = ground terminal 11 = ground terminal 12 = conductor R1-R (normally closed contact) 13 = conductor R1-A (normally open contact) 14 = neutral conductor N

Depending on the product version, power supply cable and sensor cables are already connected to the device. If that is not the case, please proceed as follows:

Connect the temperature sensors (S1 to S3) to the corres ponding terminals with either polarity:

1/2 = Sensor 1 (e. g. sensor collector) 3/4 = Sensor 2 (e. g. sensor tank) 5/6 = Sensor 3 (e. g. sensor tank top)

Connect the RESOLVBus

to the terminals marked

“VBus” with either polarity:

7 = VBus terminal 8 = VBus terminal

Connect the power supply cable to the following terminals:

15 = neutral conductor N 16 = conductor L 9 = ground terminal

Attach ﬂexible cables to the housing with the enclosed strain relief and the corresponding screws.

ATTENTION! ESD damage!

Electrostatic discharge can cause damage of electronic components!

CMX:

collector maximum temperature adjustment range: 100 ... 190 °C 210 ... 380 [°F] factory setting: 120 °C; 250 [°F] hysteresis: 5 K (10 °Ra)

System cooling

When the adjusted maximum tank temperature is reached, the system stagnates. As soon as the collector temperature reaches the adjusted maximum collector temperature (CMX) the solar pump is activated until the collector temperature is 5 K (10 °Ra) lower than the maximum temperature. The tank temperature may increase, but only up to 95 °C (200 °F) (emergency shutdown of the tank).

OCX: option system cooling adjustment range: OFF / ON factory setting: OFF

Maximum tank temperature

Once the adjusted maximum temperature is exceeded, the solar pump is switched off and further loading of the tank is prevented to reduce scald risk or system damage. The symbol is shown on the display.

S MX: maximum tank temperature adjustment range: 4 ... 95 °C 40 ... 200 [°F] factory setting: 60 °C; 140 [°F] hysteresis: 2 K (4 °Ra)

Collector temperature limitation for emergency

shutdown of the collector

If the adjusted collector emergency shutdown temperature (EM) is exceeded, the controller switches off the solar pump in order to protect the system against overheating. The factory setting is 140 °C (280 °F) but it can be changed within the adjustment range of 110 ... 200 °C (230 ... 400 °F).

(ﬂashing) is shown if EM is exceeded.

EM: collector temperature limitation adjustment range: 110 ... 200 °C 230 ... 400 [°F] factory setting: 140 °C; 280 [°F] hysteresis: 10 K (20 °Ra)

Note:

The controller is also equipped with a nonadjustable emergency switch-off if the tank reaches 95 °C (200 °F).

If the switch-on difference (DT O) is reached, the pump is activated. If the temperature difference falls below the adjusted switch-off temperature difference (DT F) the controller switches off.

Note:

The switch-on temperature difference must be at least 0.5 K (1 °Ra) higher than the switch-off temperature difference.

CMN:

collector minimum temperature adjustment range: 10 ... 90 °C 50 ... 200 [°F] factory setting: 10 °C; 50 [°F]

Option collector minimum limitation

OCN:

collector minimum limitation adjustment range: OFF / ON factory setting: OFF

The collector minimum limitation option prevents the solar pump from being switched on too often at low collector temperatures. When this option is activated, the collector minimum temperature can be adjusted. The collector minimum temperature is the temperature which must be exceeded for the solar pump (R1) to switch on. If the temperature falls below the minimum temperature,

(ﬂashing) is shown.

CFR:

antifreeze temperature adjustment range:

-10 ... 10 °C 10 ... 50 [°F] factory setting:

4.0 °C; 40 [°F]

Antifreezeoption

OCF:

antifreeze function adjustment range: OFF / ON factory setting: OFF

The antifreeze function activates the loading circuit between the collector and the tank when the temperature falls below the adjusted antifreeze temperature at the collector sensor. This will protect the ﬂuid against freezing or coagulating. When this option is activated, the antifreeze temperature can be adjusted. If the adjusted antifreeze temperature is exceeded by 1 °C (2 °Ra), the loading circuit will be deactivated.

Option recooling

If the adjusted maximum tank temperature (S MX) is reached, the controller keeps the solar pump running in order to prevent the collector from being overheated. The tank temperature may increase, but only up to 95 °C (200 °F) (emergency shutdown of the tank).

If the tank temperature is higher than the maximum tank temperature (S MX) and if the collector temperature is at least 5 K (10 °Ra) below the tank temperature, the solar system remains activated until the tank is cooled down below the adjusted maximum tank temperature (S MX) via the collec tor and the pipework.

OREC:

option recooling adjustment range: OFF / ON factory setting: OFF

Note: Since this function uses the limited heat quantity of the tank, the antifreeze function should be used in regions with few days of temperatures around the freezing point.

If the OREC option is additionally activated:

If the tank temperature is higher than the maximum tank temperature (S MX) and if the collector temperature is at least 5 K (10 °Ra) below the tank temperature, the solar system remains activated until the tank is cooled down below the adjusted maximum temperature (S MX) via the collector and the pipework. If the system cooling function is activated,

(ﬂashing) is shown. Due to the cooling function, the system will have a longer operation time on hot summer days and guarantees thermal relief of the collector ﬁeld and the heat transfer ﬂuid.

Evacuated tube collector function

If the controller detects an increase in collector temperature by 2 K (4 °Ra) compared to the previously stored collector temperature, the solar pump will be switched-on for about 30 seconds in order to detect the ﬂuid temperature. The current collector temperature will be saved as a new reference value. If the measured temperature (new reference value) is exceeded by 2 K (4 °Ra), the solar pump will run for 30 seconds. If the switch-on difference between the collector and the tank is exceeded during the runtime of the solar pump, the controller will automatically switch to solar loading. If the collector temperature decreases by 2 K (4 °Ra) during a loading break, the switch-on value for the evacuated tube collector function will be recalculated.

yes

Is the pump stuck?

Turn the pump shaft using a screwdriver; now passable?

This additional module enables the acquisition and storage of large amounts of data (such as measuring and balance values of the solar system) over a long period of time. The DL2 can be conﬁgured and read-out with a standard internet browser via its integrated web interface. For transmission of the data stored in the internal memory of the DL2 to a PC, an SD card can be used. The DL2 is appropriate for all controllers with RESOL VBus

. It can be connected directly to a PC or router for remote access and thus enables comfortable system monitoring for yield monitoring or for diagnostics of faults.
