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.

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!

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

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).

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.

In order to block the thermostat function for a certain period, there are 3 time
frames t1 … t3.
If the thermostat function is supposed to run from 06:00 a.m. to 09:00 a.m. only,
adjust t1 O to 06:00 a.m. and t1 F to 09:00 a.m.
If the switch-on and switch-off times of a time frame are set to an identical value,
the time frame will be inactive. If all time frames are set to 00:00, the thermostat
function is solely temperature dependent (factory setting).

Factory setting: 60 °C [140°F]
This function helps to contain the spread of Legionella in DHW stores by system-
atically activating the afterheating.
For thermal disinfection, the temperature at the reference sensor will be moni-
tored. Protection is ensured when, during the monitoring period, the disinfection
temperature is continuously exceeded for the entire disinfection period.
The monitoring period starts as soon as the temperature at the reference sensor
falls below the disinfection temperature. When the monitoring period ends, the
allocated reference relay activates the afterheating. The disinfection period starts,
if the temperature at the allocated sensor exceeds the disinfection temperature.
Thermal disinfection can only be completed when the disinfection temperature
is exceeded for the duration of the disinfection period without any interruption.
Starting time delay
SDIS
Starting time
Adjustment range: 0:00 … 24:00 (time)
Factory setting: 00:00
If the starting delay option is activated, a starting time for the thermal disinfection
with starting delay can be adjusted.The activation of the afterheating is then delayed
until that starting time after the monitoring period has ended.
If the monitoring period ends, for example, at 12:00 o'clock, and the starting time
has been set to 18:00, the reference relay will be energised with a delay of 6 hours
at 18:00 instead of 12:00 o'clock.
Note
If the thermal disinfection option is activated, the display channels TDIS,

Arrangement 3:
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.
If the maximum collector temperature (CMX) is reached, the solar pump will be
activated by R1 and the 3-port valve by R2 in order to direct the surplus energy
to a heat dump. For safety reasons, excess heat dump will only take place as long
as the store temperature is below the non-adjustable shutdown temperature of
95 °C [200 °F].
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.
