3.2 Main parts

 Solar hot water tank

- Tank in enamelled steel

- Solar coil

- Insulation in CFC-free polyurethane foam

- External PVC casing - white

 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

contact) for significant unforeseen needs.

` By programming the heating time outside off-peak periods (2

hours maximum according to the DHW volume at 40°C

required) to compensate for the lack of sunshine in winter, for

example. The programmed period outside off-peak hours must

preferably be between 12 h and 18 h.

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.

 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

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.
