Manual Version 1.26

Safety requirements

This device is state of the art and meets all necessary safety regulations. It may only be used

in accordance with the technical data and the safety requirements and regulations listed be-

low. When using the device, also observe the statutory and safety regulations apposite to

the particular use. Any other use will automatically void all warranty rights.

• The device must only be installed in a dry interior room.

• It must be possible to isolate the controller from the mains using an omnipolar isolating

facility (plug/socket or 2-pole isolator).

• Before starting installation or wiring work, the controller must be completely isolated

from the mains and protected against reconnection. Never interchange the safety low

voltage connections (e.g. sensor connections) with the 230 V connections. Destruction

and life threatening voltages at the device and the connected sensors may occur.

• Solar thermal systems can become very hot. Consequently there is a risk of burns. Pro-

ceed with caution when fitting temperature sensors.

• For safety reasons, the outputs should only be left in manual mode when testing. In this

operating mode, no maximum temperatures or sensor functions are monitored.

• Safe operation is no longer possible if the controller or connected equipment exhibits

visual damage, no longer functions or has been stored for lengthy periods in unsuitable

conditions. If this is the case, disable the controller and equipment and secure against

unintentional use.

Maintenance

If treated and used correctly, the device will not require any maintenance. Use a cloth mois-

tened with mild alcohol (such as methylated spirits) to clean. Never use corrosive cleaning

agents or solvents such as chloroethylene or trichloroethylene.

No components relevant to long term accuracy are subject to loading if the device is used

correctly. Consequently long term drift is extremely low. The device therefore cannot be cal-

ibrated. Thus applying any compensation is impossible.

The design characteristics of the device must not be changed during repairs. Spare parts

must correspond to the original spare parts and must be used in accordance with the build

version.

Disposal

• Devices no longer in use or beyond a state of repair must be disposed of

in an environmentally responsible manner by an authorised collection point.

They mus never be treated as ordinary household waste.

• We can undertake the environmentally responsible disposal of devices

sold by the Technischen Alternative company upon request.

• Packaging material must be disposed of in an environmentally responsible

manner.

• Incorrect disposal may result in considerable damage to the environment,

as many of the materials used require professional handling.

All installation and wiring work on the controller must only be carried out

in a zero volt state. The opening, connection and commissioning of the

device may only be carried out by competent personnel. While doing so,

they must observe all local safety requirements.

Installing the device

Opening the module

Unscrew the screws on the front and lift the cover.

The electronics are located in the cover. The connection to the terminals in the lower section of the

enclosure is made by contact pins when the cover is put in place.

The lower section can be wall mounted through the slots provided (with the cable entries in the side

facing down) or mounted on a top-hat rail (TS35 support rail as defined by the EN50022 standard).

Mounting dimensions

CAUTION: Always pull the mains plug before opening the enclosure!

Only work inside the module when the power supply is at zero volt.

Dimensions drawing of enclosure

Sensor installation

Correct arrangement and installation of the sensors is extremely important for correct functioning

of the system. To this end, also ensure that they are completely inserted in their sensor wells. The

cable fittings provided serve as strain relief. When used outdoors, no water must be allowed to

penetrate the sensor wells (risk of frost). The contact sensors must be insulated well to protect

them from being influenced by the ambient temperature.

Fundamentally, sensors should not be exposed to moisture (such as condensation) since this can

diffuse through the cast resin and damage the sensor. If this happens, heating the sensor to 90 °C

for an hour may help. When using sensor wells in stainless steel cylinders or swimming pools,

particular attention must be given to their corrosion resistance.

•Collector sensor (grey lead with junction box): Either insert into a pipe which is brazed

or riveted directly to the absorber and protrudes from the collector housing, or insert a

tee into the flow manifold of the outermost collector into which the sensor well, together

with the brass cable fitting (= protection against moisture), can be inserted; then insert

the sensor. To protect against lightning damage, the junction box has a surge protection

(voltage dependent resistor) which is clamped in parallel between the sensor and the

extension cable.

•Boiler sensor (boiler flow): This sensor is either inserted into a sensor well in the boiler

or fitted to the flow line as close to the boiler as possible.

•DHW cylinder sensor: The sensor required for the solar thermal system should be used

with a sensor well for finned tube heat exchangers just above the exchanger or, if inte-

grated smooth tube heat exchangers are used, in the lower third of the exchanger or the

exchanger’s return outlet so that the sensor well protrudes into the heat exchanger tube.

The sensor monitoring the heating of the DHW cylinder by the boiler is installed at a level

corresponding to the amount of domestic hot water required during the heating season.

The supplied cable fitting acts as strain relief. Installation below the associated coil or

heat exchanger is not permissible under any circumstances.

•Buffer sensor: The sensor required for the solar thermal system is fitted in the lower sec-

tion of the cylinder just above the solar indirect coil using the sensor well supplied. The

supplied cable fitting acts as strain relief. As the reference sensor for the heating system

hydraulics, it is recommended to insert the sensor into the sensor well between the cen-

tre and upper third of the buffer cylinder, or positioned against the cylinder wall under-

neath the insulation.

•Pool sensor (swimming pool): Fit a tee into the suction line immediately on the pool out-

let and insert the sensor with a sensor well. In the process, ensure the material used is

corrosion-resistant. A further option would be to fit the sensor as a contact sensor with

appropriate thermal insulation against ambient influences.

•Contact sensor: Use scroll springs, pipe clips, etc. to attach the contact sensor to the

respective line. Ensure the material used is suitable (corrosion, temperature resistance,

etc.). Then insulate the sensor thoroughly so that the pipe temperature is captured accu-

rately and ambient temperatures cannot falsify the result.

•DHW sensor: A rapid reaction to changes in the water volume is extremely important

when using the controller in systems that generate domestic hot water by means of an

external heat exchanger and variable speed pump (freshwater module). Therefore fit the

DHW sensor directly on the heat exchanger outlet. This ultra-quick sensor (special

accessory, type MSP ...) should protrude into the output with the aid of a tee sealed in

with an O-ring. The heat exchanger should be installed upright with the DHW outlet at the

top.

•Radiation sensor: The parallel collector orientation is important in order to obtain a mea-

surement that corresponds to the collector position. Consequently it should be secured

to the sheet steel covering or adjacent to the collector on an extension of the mounting

rail. To this end, the sensor casing has a blind hole that can be opened at any time. The

sensor is also available as a wireless version.

•Room sensor: This sensor is intended for installation in the living space (reference

room). Do not install the room sensor near a heat source or window. By simply replug-

ging a jumper inside the sensor, each room sensor can also be used exclusively as a

remote adjuster (no room temperature influence). It is only suitable for operation in dry

rooms. The sensor is also available as a wireless version.

•Outside temperature sensor: This sensor is installed on the coldest wall (usually facing

north) some two meters above the ground. Avoid temperature influences from nearby air

shafts, open windows, cable ways, etc. It must not be subjected to direct insolation.

Electrical connection

This must only be carried out by a qualified electrician in accordance with the relevant local

regulations.

Note: In line with regulations, the system must be equipped with protection against lightning

(surge arrester). Sensor failures due to thunderstorms and static electricity are usually the

result of missing or incorrect earthing or missing surge protection.

Caution: Only work inside the module when the power supply is at zero volt. Assembling the

device with the power connected may result in damage.

Connect all sensors and pumps/valves as they are numbered in the respective program.

In the mains voltage range, fine wire cross-sections of 0.75 - 1.5 mm² are recommended, ex-

cept for the supply cable.

A terminal strip is provided in the 230 V terminal box for connection of the earth conductor

(PE). All cables can be fixed with a locking clamp (= strain relief) immediately after termina-

tion. Subsequently, side cutters are required to remove the locking clamps; therefore, more

clamps than necessary are provided.

Terminal diagram

View of the lower enclosure section with terminals:

Mains connection

Power is supplied through a power supply unit integrated into the module. The mains connection

must therefore be 230 V 50 Hz. This is also the voltage conducted by the output relay. The integral

power supply unit also supplies power to the CAN bus.

Sensor leads

Sensor terminal diagram

Sensors are always connected across the relevant sensor terminal (S1 – S6) and sensor earth (GND).

There is an earth strip in the base. A connection to the GND terminal must be laid using this strip be-

fore the sensors are connected.

In order to prevent measurement fluctuations and ensure perfect signal transmission, sensor leads

must not be subject to external negative influences through 230 V cables.

Never run sensor leads together with mains voltage cables in the same conduit.

When using non-screened cables, route sensor leads and 230 V cables either in separate cable con-

duits or with a minimum clearance of 5 cm.

Sensor leads for PT100 or PT500 sensors must be screened.

If screened cables are used, the screen must be connected to the sensor earth (GND)

All sensor leads with a cross-section of 0.5 mm2 can be extended to up to 50 metres. With this lead

length and a PT1000 temperature sensor, the measuring error is approximately +1 K. A correspond-

ingly larger cross-section is required for longer leads or a lesser measuring error.

The connection between the sensor and the extension can be made by pushing heat shrink tubing

(trimmed to 4 cm) over one core and twisting the bare wire ends. Solder the connection if one of the

wire ends has been tin-plated.

Then push the heat shrink tubing over the connection and heat up carefully (e.g. with a lighter) until

it sits tightly over the connection.
