ÎInstall the mains plug such that it is accessible at any time.
ÎIf this is not possible, install a switch that can be accessed.
Do not use the device if it is visibly damaged!
The power supply of the device must be 100 … 240 V~ (50 … 60 Hz). Attach exible
cables to the housing with the enclosed strain relief and the corresponding screws.

pump, a valve, etc. can be connected:
• Relay 1 • Relay 2
18 = Conductor R1 16 = Conductor R2
17 = Neutral conductor N 15 = Neutral conductor N
13 = Grounding terminal ⌯14 = Grounding terminal ⌯
Note
The pump speed must be set to 100% when auxiliary relays or valves are
connected.
The mains connection is at the following terminals:
19 = Neutral conductor N
20 = Conductor L
12 = Grounding terminal ⌯

2.3 Data communication / Bus
The controller is equipped with the RESOL VBus®for data transfer and energy
supply to external modules. The connection is to be carried out at the terminals
marked VBus (any polarity).
One or more RESOL VBus®modules can be connected via this data bus, such as:
• RESOL DL2 Datalogger
• RESOL DL3 Datalogger
• VBus®/ PWM interface adapter
Furthermore, the controller can be connected to a PC or integrated into a net-
work via the RESOL VBus®/ USB or VBus®/ LAN interface adapter (not included).
Different solutions for visualisation and remote parameterisation are available on
the RESOL website www.resol.com.

2.5 Systems
Arrangement 1:
The controller calculates the temperature difference between collector sensor S1
and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference (DT O), the solar pump will be activated by the
relay, and the store will be loaded until the switch-off temperature difference (DTF)
or the maximum store temperature (S MX) is reached.
Sensors S3 and S4 can optionally be connected for measurement purposes. S3 can
optionally be used as the reference sensor for the store emergency shutdown op-
tion (OSEM).
If heat quantity measurement (OHQM) is activated, S4 is to be used as the return
sensor.
If the drainback option (ODB) is activated, relay 2 can be used for activating a booster
pump. For this purpose, the booster function (OBST) has to be activated.

and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference (DTO), the solar pump will be activated by relay
1, and the store will be loaded until the switch-off temperature difference (DTF) or
the maximum store temperature (S MX) is reached.
Sensor S3 is used for a thermostat function which operates relay 2 for afterheat-
ing or heat dump purposes when the adjusted thermostat switch-on temperature
(AH O) is reached.This function can optionally be combined with up to three ad-
justable time frames.
S3 can optionally be used as the reference sensor for the thermal disinfection func-
tion (OTD).
Sensor S4 can optionally be connected for measurement purposes. If heat quantity
measurement (OHQM) is activated, S4 is to be used as the return sensor.
