Strong electromagnetic elds can impair the function of the con-

troller.

ÎMake sure the controller as well as the system are not exposed to

strong electromagnetic elds.

The unit must only be located in dry interior rooms.

The controller must additionally be supplied from a double pole switch with contact

gap of at least 3 mm.

Please pay attention to separate routing of sensor cables and mains cables.

In order to mount the device to the wall, carry out the following steps:

ÎUnscrew the crosshead screw from the cover and remove it along with the

cover from the housing.

ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall

plug and screw leaving the head protruding.

ÎHang the housing from the upper fastening point and mark the lower fastening

point (centres 130 mm).

ÎInsert lower wall plug.

ÎFasten the housing to the wall with the lower fastening screw and tighten.

ÎCarry out the electrical wiring in accordance with the terminal allocation (see

2.2 Electrical connection

WARNING! Electric shock!

Upon opening the housing, live parts are exposed!

ÎAlways disconnect the device from power supply

before opening the housing!

ATTENTION! ESD damage!

Electrostatic discharge can lead to damage to electronic com-

ponents!

ÎTake care to discharge properly before touching the

inside of the device!

Note

Connecting the device to the power supply must always be the last step

of the installation!

Note

It must be possible to disconnect the device from the mains at any time.

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.

The controller is equipped with 2 semiconductor relays to which a load such as a

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.

Arrangement 2:

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 (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.
