and screws.
Depending on the version the controller is equipped with
1 relay (PG 51.02 and PG52.02) or 2 relays (PG 53.02 and
PG54.02, cp. overview „Controller versions“ on p. 3) to
which the consumers e.g. pumps, valves etc. can be
connected:
• Relay 1 (PG 52.05 and PG 54.02)
18 = conductor R1
17 = neutral conductor N
13 = ground clamp
• Relay 2 (PG 53.02 and PG 54.02)
16 = conductor R2
15 = neutral conductor N
14 = ground clamp
The temperature sensors (S1 up to S3) will be connected
to the following terminals independently of the polarity:
1 / 2 = sensor for heat source (e.g. collector sensor)
3 / 4 = sensor for heat sink (e.g. store sensor)
5 / 6 = additional sensor (PG 51.02 and PG 52.02)

2. Sensor types
Precision-platin sensors type PT1000 (FKP and FRP) are
used for DeltaSol® B.
The arrangement of the sensors is of great importance to
the total efficiency of the regulator. The collector
temperature should be measured in the upper part of the
collector. In stores with integral heat exchanger, the sensor
must be directly mounted in the upper part of the heat
exchanger.When using external heat exchangers, the sensor
must be fixed at the bottom of the store. For individual
operation systems, our product range contains 3 different
types of sensors (sensors for installation in existing
immersion sleeves, flatscrew sensors or cylindrical clip-on
sensors). The sensor types FK and FR have the same
electrical features and are available in the same models,They
only differ in the connecting cable:
FK: 1,5 m weather- and temperature resistant silicone cable
for temperatures between -50 °C ... +180 °C, mostly used
for collectors.
FR: 2,5 m PVC cable for tempertures between
-5 °C ... +80 °C, mostly used 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 higher voltages 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); screened cables should be used
preferably. The sensors must not be in direct contact with
water, please always use immersion sleeves.
Immersion sensors: in different lengths (immersion
depth) available
FK...60: 60 mm immersion depth, immersion sleeves of
chromium-plated brass
FK...150: 150 mm immersion depth, immersion sleeve of
chromium-plated copper
Important: The sensors must be completely pushed into
the sleeve and the nut must be slightly tightenend.
FK... : collector sensor
FR... : reference sensor (store sensor)
Flatscrew sensors: for installation on flat surfaces
FK...9 or FR...9
Ensure good thermal contact. Use conduction paste and
insulate the sensors against outside temperature influences.
Indication:
In order to avoid overvoltage damage at the collector (e.g.
by lightening), it is highly recommendend to use the
overvoltage protection RESOL SP1.
© RESOL 08015 deltasol_b.monen.pmd
Cylindrical clip-on sensors: for any pipe diameter; cpl.
with fastening collar; FK...21 or FR...21
Ensure good thermal contact of the sensor with the pipe
work by cleaning the contact area and by applying heat
conduction paste between sensor and pipe. In order to
protect the sensor cable against outside temperature
influences, it is recommended to insulate the pipe..

(maximum store temperature is reached), the solar pump
(R1) switches-on and cools the collectors by heat transfer
via lines and the store (collector cooling function).The store
temperature might increase, but only up to 90 °C (safety
shutdown of the store). This function guarantees a longer
operating time for very hot summer days and ensures a thermal relief for the collectors and the heating medium. The
maximum collector temperature is set to 120 °C by RESOL,

If individual conditions require an adaptation of the
parameter, please adjust the values accordingly (see 3.2).
5. Tips for fault location:
Attention!
Before opening the housing
please make sure that all poles
are separated from the line
voltage.
Please check the following points if the controller
ol® B 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
situated 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).
Depending on the PG ver sion

2. Sensor faults
If there is a malfunction due to a sensor defect, the operating
control lamp flashes red and the symbol
is shown on the
display (T3 is not affected).An error code for the concerned
sensor is shown on the display (TC, TS or TT).The pushbutton
key <+> must once be pressed for checking the 3rd
temperature sensor.
Short-circuit:
Short-circuit in the sensor wire with
indication of the concerned temperature sensor (TC, TS or
TT). The error code -888.8 is shown on the display.

6. Examples
6.1 Solar system with 1 collector and 1 store:
1
S1
2
S3
3
S2
4
Solar irradiation transfers heat, which is made utilizable by
the heat exchanger of the store (4), via collector (2) to the
system. The controller (1) measures the temperature
difference between collector sensor S1 and store S2. As
soon as this difference is higher or identical to the adjusted
value (DO), the pump (3) is started and the store is loaded
up. If the switch-off temperature difference (DF) is underrun
by this difference, the pump is stopped.
The 3rd temperature sensor S3 is an additional sensor for
measuring purpose, e.g. for measuring the upper store
temperature.
6.2 Solar system with 1 collector, 1 store and after
heating (only PG 53.02/54.02):
1
S1
2
S3
4
S2
Solar irradiation transfers heat which is made utilizable by
the heat exchanger of the store (4) via collector (2) to the
system (2). The controller (1) measures the temperature
difference between collector sensor S1 and store sensor S2.
As soon as this difference is higher or identical to the
adjusted value (DO), the pump (3) is started and the store
is loaded up. If the switch-off temperature difference (DF)
is underrun by this difference, the pump is stopped.
The 3rd temperature sensor S3 can be used for thermostat
function. The thermostat switch-on temperature (TO) and
the switch-off temperature (TF) must be adjusted in the
adjustment channels. Depending on your adjustment, the
thermostat function works in after-heating or cooling
opertion.
Necessary adjustments for store after-heating:
TO = 40 °C
TF = 45 °C
The adjustmens can be adapted to the individual system
conditions.

The controller (1) compares the temperature measured by
sensor S1 at the buffer store (2) with the reverse temperature at measuring sensor S2. If the measured temperature difference is higher or identical to the adjusted
value ΔT, the reverse temperature is increased by the
warmth of the buffer store when connecting the 3-wayvalve (3)(heating support) .
6.4 Loading of the store by solid fuel boiler or chimney boiler:

The controller (1) compares the temperatures measured
by sensor S1 in the boiler or chimney boiler (2) with the
temperature measured by sensor S2 in the store (3). If the
measured temperature difference is higher or identical to
the adjusted value DO (switch-on temperature difference),
the pump (4) is activated, if the adjusted minimum
temperature (CN, adjustment range 10,1 ...90 °C) is
simultaneously reached or exceeded. If the switch-off
temperature difference DF or the minimum temperature is
underrun, the pump switches-off.
Necessary adjustment for minimum temperature limitation
(to avoid flue gas condensation):
CN = 60 °C (recommended)

6.5 After-heating of the boiler by buffer store:
1
S1

S2
The controller(1) measures the temperature difference
between buffer store sensorS1 and store sensor S2. As soon
as the difference is higher or identical to the adjusted value
(DO), the pump (3) is activated and the store is loaded up.
If the switch-off difference (DF) is underrun by the measured
difference, the pump is again deactivated.
The 3rd temperature sensor S3 is an additional sensor for
measuring purpose, e.g. for measuring the upper store
temperature.
6.6 Swimming pool solar system:
S1

2
S2
The controller (1) measures the temperature difference
between collector sensor S1 and swimming pool reverse
sensor S2. As soon as the difference is higher or identical
to the adjusted value (DO), the pump (3) is activated so that
the water in the pool is heated up. If the switch-off
difference (DF) is underrun by the measured difference, the
pump is again deactivated.
The 3rd temperature sensor S3 is an additional sensor for
measuring purpose, e.g. for measuring the upper store
temperature.

to = 40 °C, tf = 40 °C
• to = tf
the thermostat function is deactivated, that means
that relay output R2 is activated if the maximum store
temperature is exceeded
• To < Tf
the thermostat function is used as after-heating
• To > Tf
the thermostat function is used as surplus energy
