General Information
Intended use
The Fluropro solar control is a temperature differential
controller for solar DHW provision with a cylinder reheat
programmer for a supplementary boiler.
The control is suitable for controlling solar systems with a
collector array and a storage cylinder.
The Fluropro solar control can be used for controlling a
second collector array
If a second collector array is connected, an additional
collector sensor (available as an accessory) must be installed.
It is possible to determine the solar gain by using an
additional gain sensor (supplied with Glow-worm Clearly Solar
sets).
The Fluropro solar control is a state-of-the-art control which
has been constructed in accordance with recognised safety
regulations. Nevertheless, improper use can cause serious
or fatal injury to the user or others, and the appliance or other
property can be damaged.
The manufacturer or supplier is not liable for any damage
resulting from improper use.
The control is not suitable for outdoor use and must be
installed in a dry room.

2 Functions
2.1 Solar gain
The Fluropro solar control works on the principal of differential
temperature control. The control always switches on the
collector pump when the difference in temperature (collector
temperature - cylinder temperature) is greater than the
programmed activation difference.
The controller switches off the collector pump when the
difference in temperature (collector temperature - cylinder
temperature) is less than the programmed deactivation
difference.
The installation engineer activates and congures the solar
gain function within the Fluropro installer menu.
The solar gain is determined from:
– The difference of temperature between the collector ow
and return.
– The ow rate setting of the ow rate adjuster.
– The operating time of the collector pump.
During installation the engineer sets the actual ow rate and
enters the setting into the solar control. The solar gain is
calculated and displayed by the solar control. The total gain
can be called up and reset in the installer menu.
2.2 Solar gain modulation
The rate of solar gain can be modulated to ensure the solar
heat at the bottom of the cylinder has sufcient time to
dissipate to the top of the cylinder. This maintains demand for
solar energy and prevents excessive on and off periods that
are inefcient.
The modulation is achieved by means of more frequent on
and off operations of the solar pump during solar demand.
The pump is switched on and off and the rate depends upon
the difference between the collector temperature and lower
cylinder sensor. When the activation difference is reached, the
function is started (if activated) with an activation duration of
50 % - i.e., the pump is switched on for 30 seconds and then
switched off for 30 seconds. If the difference in temperature
increases, the activation duration is prolonged (e.g., 45
sec. on, 15 sec. off). When the difference in temperature
decreases, the activation duration is reduced (e.g., 20 sec.
on, 40 sec. off). The period length is always a minute.
2.3 Cylinder reheat
The cylinder reheat function allows the cylinder to heat up
to the required temperature during a set time window, even
if the solar gain is insufcient. In this case the water can be
reheated using an external boiler or the immersion heater.
You can set up times for reheating the solar cylinder, refer to
Settings section in Instructions for Use.
2.5 Legionella protection
The Legionella protection function is designed to kill germs in
the cylinder and pipes.
When the function is activated, the cylinder, the hot water
pipes, and the circulation pump (if installed), are brought to
a temperature of 70°C on the programmed day(s) and at the
programmed time
In doing so, the cylinder temperature is raised to 70°C and the
corresponding circulation pump is switched on (if installed).
First, an attempt will be made using solar gain alone to reach
the target temperature over a 90 min. period. If this is not
successful, the Legionella protection is carried out using an
external boiler or an immersion heater, whichever has been
set up for this thermal protection. The Legionella protection
function will stop once a temperature of at least 70°C has
been maintained for a period of 30 minutes.
The installation engineer activates the Legionella protection
function within the Fluropro installer menu and species
whether the thermal disinfection should take place at 3:30
p.m. or at 4:00 a.m., i.e. offset gain versus cheaper electricity.
2.6 Anti-seize protection for pumps
If no pumping has occurred for 23 hours, all installed pumps
are switched on for approx. 3 seconds to prevent pumps from
seizing.
2.7 Secondary recirculation
The Fluropro solar control includes a programmer channel for
a DHW secondary return. A secondary return should not be
used with Glow-worm twin coil unvented solar cylinders.
2.8 Calendar
The controller is equipped with a calendar so that it can
automatically adjust the clock by 1hr between GMT and BST.
To activate, simply enter the current date within the Fluropro
installer menu
NOTE: In the event of a power failure, the controller only has
a power reserve of 30 minutes. After 30 minutes, the internal
clock stops and the calender will not automatically resume
function once power has been restored. In this case the time
and date will need to be reset.
2.4 Reheat delay
To prevent unnecessary cylinder reheating by a boiler or an
immersion heater, the Fluropro solar control includes a reheat
delay function. This function delays the cylinder reheat by up
to 30 mins if solar gain is available.
If the solar pump is off and the desired cylinder temperature
is not reached after the delay period, the cylinder will be
reheated using an external boiler or the immersion heater.
The reheat delay function is activated by an engineer within
the Fluropro installer menu.

It is possible to use a non Glow-worm boiler with the Glowworm solar system solution which is controlled by the
Fluropro.
In order to achieve this, consult your boiler installation manual
to determine the switched live connection to the boiler. The
switched live input is the 230v input voltage to the boiler which
makes a heating demand.
The heating demand to your non Glow-worm boiler will be
provided from the Fluropro or a third party programmer at
terminal 4 of the wiring centre.

5.4 Hand over to the householder
l Hand over all manuals to the householder.
l Advise the householder to keep the manuals near to the
system.
l Draw special attention to the safety instructions which the
householder must follow.
l Review the user instructions with the householder and
answer any questions.
l Show the householder how to operate the solar control, CH
control and any separate DHW control.
l Inform the householder that the cylinder temperature is
factory set at 65°C and that the DHW temperature can be
adjusted using the TMV by the installer.
l Inform the householder that the immersion heater is
intended as a standby device and should not be used
simultaneously with the boiler to heat the cylinder.
l Inform the householder that they are not permitted to
change the settings made on the solar system.
l Inform the householder that to ensure the continued
efcient and safe operation of the solar system it is
recommended that it is checked and serviced at regular
intervals. The frequency of servicing will depend upon the
installation conditions and usage, but in general, once a year
should be enough.
l Inform the householder that the boiler and solar cylinder
should be serviced by a qualied engineer annually.
5.3 Benchmark
GB: It is a requirement that the “Benchmark” Installation,
Commissioning and Service Record is completed and left with
the user.
IE: it is necessary to complete a “Declaration of Conformity” to
indicate compliance to I.S.813. An example of this is given in
the current edition of I.S.813.
Leave these instructions and the “Benchmark” Installation,
Commissioning and Service record document with the user.

Error messages
The Fluropro solar controller shows error messages in
the main operating menu if there is a problem with the
temperature sensor.
The sensor conguration will always be displayed when the
controller is switched on for the rst time, or if the power
has been switched off and on again. Depending on the set
hydraulic plan, the controller recognises whether there is a
problem, or if the sensor is not necessary for operation.
The following diagrams assume that the day is Monday
and that the timer is active for reheat but is not currently
reheating.
Error collector sensor (array 1)
This error occurs if the there is a problem with the collector
sensor, or if it is not connected.
Error collector sensor (array 2)
This error occurs if a sensor is connected for hydraulic plan
1. Alternatively for hydraulic plan 2 or 3, if there is a problem
with the connected sensor or it is not connected.
Error Upper cylinder sensor
This error occurs if there is a problem with the heating circuit
sensor connected.
Error Lower cylinder sensor
This error occurs if there is a problem with the solar circuit
sensor, or if it is not connected.
