1.3Datacommunication/Bus The controller is equipped with a RESOL VBus®for data
transfer with and energy supply to external modules.The
connection is carried out at the terminals marked “VBus”
(either polarity). One or more RESOL VBus®modules can
be connected via this data bus, such as
•GA3 large display, SD3 smart display
•DL2 datalogger
•VBus®/USB or VBus®/LAN interface adapter
•VBus®/PWM interface adapter
•AM1 alarm module
•WMZ calorimeter module
By means of a DL2 datalogger or an interface adapter, the
controller can be connected to a PC or a computer net-
work.With the RESOL ServiceCenter Software (RSC) the
controller measurements can be read out, processed and
visualised.The software allows easy function control of the
system. For the remote parametrisation of the controller, a
special software tool will be available for download, soon.
VBus®
connection terminals
Connecting the device to the mains supply must always be
the last step of the installation!
The power supply to the controller must be carried out via
an external power switch (last step!). The supply voltage
must be 100 ... 240 V~ (50 ... 60 Hz). Flexible cables must
be attached to the housing with the enclosed strain relief
and the corresponding screws.
The controller is equipped with two semiconductor re-
lays, to which loads such as pumps, valves etc. can be
connected:
•Relay 1
18 = conductor R1
17 = neutral conductor N
13 = ground conductor
•Relay 2
16 = conductor R2
15 = neutral conductor N
14 = ground conductor
The mains supply is to be carried out at the terminals:
19 = neutral conductor N
20 = conductor L
12 = ground terminal
The temperature sensors (S1 up to S4) are to be
connected to the following terminals with either polarity:
1 / 2 = Sensor 1 (e.g. Sensor collector 1)
3 / 4 = Sensor 2 (e.g. Sensor store 1)
5 / 6 = Sensor 3 (e.g. Sensor store top)
7 / 8 = Sensor 4 (e.g. Sensor return)
All Pt1000 temperature sensors are equipped with a
platinum measuring element in their tip. The electrical
resistance of the measuring element changes in relation
to the temperature (see table in chap. 5).
The difference between FKP and FRP type sensors only
lies in the cable insulation material. The insulation material
of FKP type sensor cables resists a higher temperature, so
that FKP type sensors should be used as collector sensors.
FRP type sensors are best used as reference sensors in
stores or pipes.

∆T control for the heat exchange between 2 stores
DT3O:
Switch-on temperature diff.
Adjustment range:
1.0 ... 20.0 K [2.0 ... 40.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
6.0 K [12.0°Ra]
DT3F:
Switch-off temperature diff.
Adjustment range:
0.5 ... 19.5 K [1.0...39.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
4.0 K [8.0°Ra]
Reference sensors for this function are S3 and S4.
In system layout 2 the controller is equipped with an addi-
tional differential control for heat exchange between two
stores. The basic differential function is adjusted using the
switch-on (DT3O) and switch-off (DT3F) temperature
differences.
When the temperature difference exceeds the switch-on
temperature difference, relay 2 switches on. If the tempe-
rature difference then falls below the adjusted switch-off
temperature difference, relay 2 switches off.
Note:
The switch-on temperature difference must be
at least 0.5 K [1°Ra] higher than the switch-off
temperature difference.
DT3S:
Nominal temperature difference
Adjustment range:
1.5 ...30.0 K [3.0 ... 60.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
10.0 K [20.0 °Ra]
RIS3:
Rise
Adjustment range:
1 ... 20 K[2 ... 40 °Ra]
in steps of 1 K [2 °Ra]
Factory setting: 2 K [4°Ra]
Pump speed control
A relative minimum pump speed can be allocated to the
output R2 via the adjustment channel n2MN.
n2MN:
Pump speed control
Adjustment range: 30 ...100
in steps of 5 %
Factory setting: 30
Note:
When loads which are not speed-controlled (e.g.
valves) are used, the value must be set to 100 % in
order to deactivate pump speed control.
Minimum pump speed
When the switch-on temperature difference is reached, the
pump is activated at full speed for 10 seconds.Then,the speed
is reduced to the minimum pump speed value (n2MN).
If the temperature difference reaches the adjusted nominal
temperature difference (DT3S), the pump speed increases by
one step (10 %).If the difference increases by the adjustable rise
value,the pump speed increases by 10 % respectively until the
maximum pump speed of 100 % is reached.The response of
the controller can be adapted via the parameter RIS3.
Note:
The nominal temperature difference must be
at least 0.5 K [1°Ra] higher than the switch-on
temperature difference.
Note:
For pump speed control of the heat exchange
pump, the operation mode of relay 2 (MAN2)
must be set to Auto.
System-specific functions The following adjustments are used for the specific function
in system layout 2.
