RESOL DeltaSol® KS is particularly conceptualized as a
controller with microprocessor technology for the demands
of solar swimming pool systems. The newly developed combi-
ned LC display in combination with 3 adjustment keys enables
an intuitive and secure controller configuration as well as an
understandable visualization of the operating states of the
system. The housing is protected against dripping water and
enables a simple and quick installation.
The swimming pool controller is equipped with all necessa-
ry controller functions for a secure and efficient operation
of the system and a second standard relay output for an
optional thermostat function, by which also e.g a cooling or
after-heating can be effected.
Please note:
The front plate of the cover can be designed individually. You
just have to design a front foil according to your individual
ideas, print it with a standard colour printer (examples are
available on request for free or via internet: www.resol.
de, solar controller, DeltaSol® KS) and insert it into the
hinged lid.

The installation and operation of the controller have to be carried out due to current standards and technical regulations. Rules for accident preventions
due to the cooperative building associations must be strictly adhered to. An inadmissable utilization or changes during the mounting or construction will
result in an exclusion of liability.
1. Mounting
1.1 Wall mounting
Warning!
Switch-off power supply before opening the hou-
sing.
The DeltaSol® KS controller doesn‘t require any further
adjustments for the standard operation after the installation.
All adjustments are carried out by a technician during the
commissioning. Fault repair and adjustment changes are only
to be carried out by specialised staff.
In order to open the cover you have to detach the locking
screw and open the lid. Screw in the upper screw up to a
minimum clearance of 2,5 mm into the wall and fit it into the
upper fastening hole. Afterwards straighten the controller
and mark both lower holes onto the wall. After having taken
off the hosing, bore the two lower dowel holes. For the upper
fastening of the housing screw the round head screw (Ø 4 x
35 mm) so far in that the housing can still be fastened. The
housing has to be fastened by fixing two screws (Ø 4 x 35
mm) in the lower part of the housing to the wall.

1.2 Electrical wiring
The power supply to the controller must only be effected
by an external power supply switch (last step of installation!)
and the line voltage must be 210 ... 250 Volt (50...60 Hz).
Flexible lines are to be fixed at the housing by enc-
losed strain relief supports and screws. The controller
is equipped with 2 standard relays, to which consu-
mers e.g. pumps, valves etc. can be connected:
R1R = relay 1, normally closed contact
R1A = relay 1, normally open contact, solar pump connection
R2 = R2 conductor, connection for additional pump or valve
N = neutral conductor N
Earth terminal = earth terminal block
The power supply is effected to the terminals
labelled with „net“
N = neutral conductor N
L = conductor L
Earth terminal = earth terminal block
Temperature sensors (S1 to S3) will be connected to the
following terminals independently of the polarity:
S1 / GND = Temperature sensor S1
S2 / GND = Temperature sensor S2
S3 / GND = Temperature sensor S3
sensor terminals
consumer terminals
net terminals
earth terminal block
Additionally, the controller must be equipped with an all-
polar gap of at least 3 mm or with a gap according to the
valid installation regulations, e.g. LS-switches or fuses.
The cable bushings at the housing are suitable for fixed and
flexible lines with an outer diameter of 5 mm to 12 mm .
Induct the lines from the bottom into the insertion slots
und and flex them into the locating channels. Dismantle the
line insulation.
Alle lines directly below the housing have to be fixed to the
wall according to the required strain relief.
Please ensure locating channels and power supply are sepa-
rated during installation.
Please pay attention to the current regulations concerning
the connection of an earthed conductor during the connec-
tion to the power supply. The power supply and low voltage
power supply are placed seperately in the wall mounting
housing due to the engineering design. The power lines have
to be taken on the right side of the housing and the low
voltage lines on the left side and connected to the blank.
There is a terminal block for the earthed conductor con-
nection in the right connection duct which can be pulled
out. After the connection of the wires the terminal has to
be plugged into the mounting again.

2. Sensor types
FK... : collector sensor
FR... : reference sensor (store sensor)
The sensors used for the DeltaSol® KS controller are
precision temperature sensors type PT1000 (FKP and
FRP).
The arrangement of the sensors is of great importance to
the total efficiency of the controller. The collector tempera-
ture should be measured at the upper part of the collector.
In stores with integral heat exchangers, the sensor with
an immersion sleeve must be mounted directly at the up-
per part of the heat exchanger. When using external heat
exchangers, the sensor with an immersion sleeve must be
fixed at the bottom of the store. For individual operation
systems, our product range contains 3 different types of
sensors: sensors with immersion sleeves, flatscrew sensors
and cylindrical clip-on sensors. The FK and FR sensor types
have the same electrical features and are available in the
same models. They differ only in the type of the connecting
cable:
Please note:
In order to avoid damage from overvoltage at the collector
(e.g. by lightening), it is highly recommendend to use the
RESOL SP1 overvoltage protection.
FK: 1,5 m weather- and temperature resistant sili-
cone cable for temperatures between -50 °C ... +180
°C, mostly utilized for collectors.
FR: 2,5 m PVC cable for tempertures between -5 °C
... +80 °C, mostly utilized for stores.
Make sure that all electrical works are carried out according
to the relevant local and IEE-regulations. The sensor cables
carry low voltages and they must not run together in a
cable conduit with cables carrying voltages higher than 50
Volts. When using longer cables or cable conduits, please use
screened cables. The sensor cables can be lengthened up to
100 m, but the cross section must be 1,5 mm² (or 0,75 mm²
up to a cable length of 50m); only screened cables should be
used. The sensors must not be in direct contact with water,
please always use immersion sleeves.

be shown one after another and then the adjusment chan-
nels will follow (see also page 7). In order to acquire these
channels, press the <+> key in channel PH for 2 sec.. After
having accessed the parameter that is to be changed, the
parameter will be activated by means of the <SET> key and
the symbol <SET> will be displayed. Now you the required
parameter value can be adjusted with the <+> key or <-> .
The adjustment has to be confirmed and finalized by pushing
the <SET> key once again.
In order to get back to the standard mode, press the <->
key several times. The controller has a built-in time-out-
function, so that after 2 min of not having pressed any key
the standard mode will be displayed.

3.4 Controller parameter and indication channels
3.5 Function description
Important notice:
By means of a internal locking mechanism, it is only possible
to adjust such pairs of values, for which the switch-on tem-
perature differential DE is at least by 0,5 K bigger than the
switch-off temperature differential DA.
The RESOL DeltaSol® KS controller controlls the tem-
perature diffence between the absorber and return flow
pool(S1 and S2) temperature and compares this difference
to a predetermined switch-on temperature differential ∆TON
(DE). The controller siwtches ON, if the measured tempera-
ture difference ∆T is bigger than or equals the value pread-
justed in the DE channel. Symbols and are displayed
and the operating control lamp flashes green (phase 0).
If the switch-off temperature differential ∆Toff (DA) between
the absorber and the return flow pool (S1 and S2) is under-
run, the R1 relay will remain switched on for the duration
of the preadjusted switch-on delay (VA). Symbols and
(flashing) are displayed and the operating control lamp
flashes green (phase 1).
If the temperature differential between the feed and return
flow (S3 and S2) of the pool after the preadjusted switch-off
temperature delay is bigger than the switch-off temperature
differential, relay R1 will remain switched on. Symbols
and are displayed and the operating control lamp flashes
green (phase 2).

If the switch-off temperature differential between the feed
and return flow of the pool is underrun, relay R1 is swit-
ched off. The following switch-on delay (VE) prevents a too
frequent switch-on of the system (clocking) and enables a
sufficient re-heating of the absorber. Symbol (flashing)
is displayed and the operating control lamp flashes green
(phase 3).
The currently active control phase (PH) and the already
terminated appropriate delay time (VA, VE) will be displayed
as check values in channels PH and VZ .

3.6 Maximum pool temperature (MX)
If the set maximum temperature at the return flow tem-
perature sensor is exceeded, a further heating of the pool
water is prevented by means of the absorber. Not until the
return flow temperature falls below a value of1 K below the
for MX set temperature, relay R1 will be switched on again
for a further pool water heating The maximum pool tempe-
rature is preadjusted to a factory setting of 3 0 °C.
If the maximum pool temperature is exceeded, symbol
is displayed,the operating control lamp flashes green.
The RESOL DeltaSol® KS controller is equipped with a
2nd relay for a thermostat function. The thermostat function
s is operated independendently from the solar operation
and can be e.g. used for an afterheating. The return flow
sensor (S2) of the pool functions as a reference sensor for
the thermostat function.
• ta = te
the thermostat function is deactivated
(factory setting)
• TA > TE
the thermostat function is used for afterheating
• TA < TE
the thermostat function is used for utilisation of excess
heat
If the 2nd relay output is switched on, symbol will be
displayed.

5. Tips for fault finding
Please check the following points if the DeltaSol® KS
controller does not work faultlessly.
1. Power supply
If the operating control lamp is off, please check the power
supply of the controller.
The controller is protected by one can fuse T4 A which is
placed at the base/isolation plate and can be replaced by
opening the cover of the housing (spare fuse is enclosed in
one of the accessory bags).
2. Sensor faults
If there is a malfunction due to a sensor defect, the opera-
ting control lamp flashes red and the symbol will appear
on the display. Additionaly, an error code for the concerned
sensor (KL or SP) will be shown. In order to check the
3rd temperature sensor the adjusment key <+> has to be
pressed once:
Short circuit: Short-circuit in the sensor line with in-
dication of the concerned temperature
sensor (S1, S2, S3/TT or S4). Error code
-888.8 is displayed.
Line break: Interruption of the sensor line with
indication of the concerned tempera-
ture sensor (s, S2, S3/TT or S4). Error
code 888.8 for the concerned sensor is
displayed.
Clamped Pt1000-temperature sensors can be checked by
a resistance-measuring device. The measured temperatures
can be compared with the resistance values of the table
opposite.

The controller measures the temperature difference bet-
ween absorber sensor S1 and return flow pool sensor S2. As
soon as the difference is bigger than or equals the set value
for the switch-on temperature differential (DE), the pump
(R1) will be switched on and by this the swimming pool will
be loaded until the switch-off temperature differential (DA)
or the maximum pool temperature (MX) is reached.
The controller measures the temperature difference bet-
ween absorber sensor S1 and return flow pool sensor S2.
As soon as the difference is bigger than or equals the set
value for the switch-on temperature differential (DE), the
reversing valve (R1A) will be switched over and by this the
swimming pool will be loaded until the switch-off tempe-
rature differential (DA) or the maximum pool temperature
(MX) is reached.
Important notice:
Relay R1 is a change-over contact (R1A = normally open
contact, R1R = normally closed contact). Pay attention to
the terminal lay-out of the valve.

6.2 Solar swimming pool system with afterheating
The controller measures the temperature difference bet-
ween absorber sensor S1 and return flow pool sensor S2.
As soon as the difference is bigger than or equals the set
value for the switch-on temperature differential (DE), the
pump (R1) will be switched on and by this the swimming
pool will be loaded until the switch-off temperature dif-
ferential (DA) or the maximum pool temperature (MX) is
reached.
An afterheating is effected by means of the return flow pool
sensor S2 via the optionally connected thermostat function
and the setting of the thermostat switch-on and switch-off
temperature (Te > Ta). The thermostat function will be
deactivated if no values Te unequal Ta are adjusted for the
thermostat switch-on and switch-off temperature.
