2 Safety instructions and recommendations
2.1 Safety instructions
Any work on the installation must be done by a qualified
professional in compliance with the codes of practice and
according to the instructions provided.
2.2 Recommendations
Have the installation regularly serviced to guarantee that it operates
correctly over time.
It is essential to check the magnesium anode in the DHW tank and
the installation and heat transporting fluid pressure every two years.
Never cut the power to the solar control system, even
during extended absences. The control system protects
the installation against overheating in summer when it is
running.
During extended absences, we recommend lowering the set
point temperature in the solar DHW tank to 50°C. When the
user is present, the set point must be set to 60°C.
Never drain the installation. Do not replace or add water or
solar fluid to the installation. These actions must be carried
out by a qualified technician.
Do not modify the control system parameters unless fully
conversant with them.

Solar station
The solar heating pump unit comprises the solar circuit safety unit, a
pressure and temperature gauge and a flowmeter to visualise
circulation of the solar fluid between the panels and the DHW tank.
An expansion vessel is connected to the solar unit; it is used to
compensate for the expansion of the solar fluid in which the
temperature varies between 0 and 150°C.
Diemasol A regulator
The control system is the solar system's brain; it makes the solar
heating pump run at variable speeds according to the difference in
temperature between the bottom of the DHW tank and the solar
panels. The control system manages the set point temperature
(temperature to be attained in the DHW tank), overheating and
nighttime cooling. The control system also displays the various
operating modes, the temperatures in the collectors and in the
bottom of the DHW tank, as well as signalling any malfunctions.

4 Setting the DHW tank outlet temperature
4.1 Programming and setting the electrical back-up
The temperature of the volume of water heated by the electrical
resistor is set by the installer on commissioning of the installation
according to the size of the home.
Using the programming device installed in the electrical panel, it is
possible to adjust the volume of water heated to 40°C by the resistor
in two ways:
` By forcing contunuous heating by the resistor (off-peak hours

5 Diemasol A solar regulator
5.1 General description of how the unit operates
In automatic mode, the Diemasol A regulator operates in accordance
with the following principles:
` The sun's rays heat the transfer fluid in the collector. For the
regulation process to be triggered, a minimum temperature of
30 °C is required in the collector and there must be a
temperature difference of 10 K by comparison with the tank.
` During the AUTO-calibration stage which follows (tu parameter
setting tu, factory setting 1 minute) the PUMPE (relay) operates
to its full extent (100%).
` Subsequently, the solar pump regime is calculated dynamically
depending on a difference between the reference temperature
(parameter DT, factory setting 20 K) and the calorifier
temperature.
` Depending on the heat available, the system heats up the solar
tank and cuts off when the tank storage temperature is reached
(adjustment parameter SX, factory setting: 60 °C).
` When the temperature in the collectors reaches the maximum
value (adjustment parameter CX, factory setting 100°C), the
solar pump is triggered to cool the collectors. The pump
continues to operate until the temperature in the collectors is
lower than 5 K at parameter CX and/or the maximum storage
temperature (80°C) is reached in the hot water storage tank.
Regulation goes into cooling mode if the preparer tank
temperature is exceeded. As soon as the temperature in the
collectors drops below the temperature in the calorifier, the
calorifier is cooled down to its set temperature. The installation
is thus protected against overheating and repeated stoppages,
allowing thus the prolonged absence of the user even in the
summer period.
5.2 Start-up
%
If the temperature in the solar collectors is higher
than 130°C, the control system operates in safety mode.
Wait until the evening before start-up or cool down (cover)
the solar collectors.
Switch on the device. The regulator starts an initialisation phase
during which the LED flashes red and green. When initialisation is
complete, the regulator changes to automatic mode. The factory
settings for this mode give optimum performance with most
installations.
If special conditions make it necessary to change the settings, the
corresponding adjustment parameters can be reset.

The regulator has a safety system that cuts off the tank at
temperatures of over 80°C.
Measured value TC - Collector temperature
The value TC shows the temperature in °C given by the collector
sensor in real time.
Measured value TS - DHW sensor temperature
The value TS shows the temperature in °C given by the tank sensor
in real time
Measured value kWh - Amount of heat
The value kWh shows in kWh the total amount of heat produced by
the installation since the regulator was put into service.
The quantity of heat (kWh value) can only be used for checks
carried out for personal reasons.
Measured value tc - Self-calibration time
The value tc shows the self-calibration phase time remaining in
seconds. During the self-calibration phase, the pump operates at full
speed (100 %); its speed is only controlled after the self-calibration
phase.

Adjustment parameter DT - Reference
temperature difference
Adjustment range: 10 ... 20 K
Factory setting: 20 K
Switching-on difference: Non-adjustable value 10 K
Switching-off difference: Non-adjustable value 5 K
The regulator reads the temperatures measured by sensors S1 (TC)
and S2 (TS) and compares the resulting temperature difference with
the switching-on difference which is preset to 10 K. Regulation is
activated when the temperature difference ∆T is equal to or greater
than the preset value. The display shows . The LED changes to
green. When the value falls below the preset 5 K switching-off
difference, the regulator switches off. The regulator tries to achieve a
temperature difference of 20 K (factory setting) between the collector
and the tank to produce high temperature hot water as rapidly as
possible. To do this, it uses dynamic speed control.
Adjustment parameter SX - Set temperature of the
solar calorifier
Adjustment range: 20 ... 80 °C
Factory setting: 60 °C
Maximum tank temperature (emergency cut-off): Non-
adjustable value 80 °C
The set temperature Sx is the desired temperature for the solar
calorifier.
If the maximum tank temperature is exceeded, tank heating is
interrupted to prevent damage due to overheating. The display
shows and (flashing) and the LED changes to flashing red/
green.
The higher the set temperature for the calorifier, the greater the
energy stored. Setting to 60 ... 75°C is suitable for normal use with
daily draw-offs.
In the event of prolonged absences (weekend, holidays):
- Reduce the calorifier temperature to 50°C
- Turn off the back-up (boiler or electrical resistance)
The installation is thus protected against overheating and the
longevity of the heat conducting fluid is conserved.

Adjustment parameter CX - Maximum collector
temperature
Adjustment range: 100 ... 125 °C
Factory setting: 100 °C
Maximum collector temperature (overheating safety): Non-
adjustable value: 130 °C.
If the temperature in the collector rises above its maximum
temperature CX even though the solar circuit is stopped (tank set
storage temperature reached), the solar pump (R1) switches on and
cools the collector (system cooling). In these conditions, the tank
temperature rises, but it can't exceed 80 °C (safety cut-off).
If the calorifier reaches the maximum temperature of 80°C (safety
shutdown), the regulator switches off the solar pump.
The collectors may reach a temperature of 160 ... 200°C, which
is normal for a solar installation.
The cooling functions allows heat to dissipate; the system thus
remains operational longer during hot summers. When it leaves the
factory, the collector's maximum temperature is preset to 100 °C;
however, it is possible to change this within the range 100 ... 125 °C.
If the maximum collector temperature is exceeded, the display shows
, and (flashing) and the LED changes to flashing red/
green.
Adjustment parameter tu - Self-calibration phase
Adjustment range: 1 ... 5 minutes
Factory setting: 1 minutes
When the solar collector reaches a minimum temperature of 30 °C
and a preset temperature difference of 10 K from the tank
temperature, the regulator switches on the solar circulating pump at
full speed for the time period set by parameter tu. During this phase,
any air bubbles present in the solar collectors or the pipes are moved
to the complete solar station by the high circulation speed in the pipes
and eliminated by the Airstop system (manual bleed degasser). After
this phase, the regulator changes to "matched flow" mode. The
remaining self-calibration time is displayed with parameter tc.
Adjustment parameter PN - Pump minimum
speed
Adjustment range: 50 ... 100%
Factory setting: 50%
Adjustment parameter PN sets a minimum value for the solar pump
speed at the relay R1 output. The lower the pump regime, the lower
its flow.

Adjustment parameter FT - Tubular solar collector
function
Adjustment range: 0/1
Factory setting: 0
0: no
1: yes
If the regulator detects a temperature rise in the collector of 2 K
compared to the last measurement, the solar pump runs at full speed
for 30 seconds to measure the current average temperature.
The measured temperature thus becomes the new reference
temperature.
If the measured temperature (new reference) then increases again
by 2 K, the solar pump starts again for 30 seconds.
The regulator switches automatically to solar heating mode if the
temperature difference between the collector and the tank exceeds
the switching-on temperature difference when the solar pump is
operating or the system is stopped.
If the collector temperature falls by 2 K while the system is stopped,
the tubular solar collector activation temperature is rechecked.
Adjustment parameter Fx - Maximum flow rate
Adjustment range: 0 ... 20 l/min
Factory setting: 6.7
In order for the regulator to calculate the quantity of heat produced by
the installation (parameter kWh), input parameter Fx. The parameter
Fx is equal to the flow in litres per minute in the solar circuit.
Determine the value Fx using the following tables, according to the
configuration of the installation and the number or surface area of the
collectors. When the flow is input incorrectly, the display kWh will also
be incorrect.
The quantity of heat (kWh value) can only be used for checks
carried out for personal reasons.
Adjustment parameter MM - Operating mode
Adjustment range: 0 ... 2
Factory setting: 2
For inspection and maintenance work, it is possible to operate the
regulator in manual mode. To operate the regulator in manual mode,
it is necessary to input parameter MM from the following table.

6 Checking and maintenance
6.1 Solar installation
We recommend that you take out a preventive maintenance contract
to check the fluid level, antifreeze protection, pressure in the system,
leak test and general operation every year or every two years.
It is imperative to drain the solar circuit before any work is
carried out.
6.2 Tank
6.2.1 Magnesium anodes
The magnesium anode must be checked by a qualified professional
at least every 2 years.
6.2.2 Safety valve or safety unit
Have the condition of the anode checked after the first year. The
magnesium anode must be checked by a qualified professional at
least every 2 years.
6.2.3 Descaling
In hard water regions, it is advisable to ask the fitter to descale the
DHW tank exchanger once a year in order to maintain its level of
performance.
6.2.4 Casing
The casing of the DHW tank can be cleaned with soapy water.
6.2.5 Vent device
If the vent device is not used, the installer must check the seal on the
top vent connection.
6.3 Solar circuit
To check operation of the solar system, consult the display on the
control system. A steady red indicator light in fine weather indicates
a malfunction.
The pressure in the solar circuit can be checked on the solar station's
pressure gauge. If the pressure shown is lower than 0.5 bar, call the
installer.
Never carry out work on the solar circuit yourself. Never
work on the safety valve yourself.
