Advice regarding the installation of temperature sensors:

Only original factory equipped Pt1000 temperature sensors are approved for use with the collector, it is

equipped with 1.5meter silicon cable and suitable for all weather conditions, the temperature sensor and

cable are temperature resistant up to 280oC, not necessary to distinguish the positive and negative polarity of

the sensor connection.

Only original factory equipped NTC10K,B=3950 temperature sensors are approved for use with tank and pipe,

it is equipped with 1.5meter PVC cable, and they are temperature resistant up to 105oC, not necessary to

distinguish the positive and negative polarity of the sensor connection.

All sensor cables carry low voltage, and to avoid inductive effects, must not be laid close to 230 volt or 400

volt cables (minimum separation of 100mm)

If external inductive effects are existed, e.g. from heavy current cables, overhead train cables, transformer

substations, radio and television devices, amateur radio stations, microwave devices etc, then the cables to

the sensors must be adequately shielded.

Sensor cables may be extended to a maximum length of ca. 100 meter, when cable’s length is up to 50m, and

then 0.75mm2cable should be used. When cable’s length is up to 100m, and then 1.5mm2cable should be

used.

Note: the connection of the pump and sensors depends on the chosen solar system, every port can only

connect one cable, fine core cables should use wire end sleeves.

3. Commissioning

Connect the sensors, pumps or switching valves to the controller before you connect the power

supply!

After switching on power to the controller, firstly it will ask for the “time” to be set and the correct

“solar system” to be chosen.

4.3 System 1

1 collector array – 1 storage tank – 1 pump

Description:

The solar circuit pump (P1) is switched on as soon as the

switch-on temperature difference between the collector

array (T1) and the storage tank (T2) is reached. If the

temperature difference between the collector array (T1)

and storage tank (T2) drops below the switch-off

temperature difference, or the storage tank (T2) reaches

the maximum storage temperature, then the solar circuit

pump is switched off.

T1: Temperature sensor for collector 1

T2: Temperature sensor in the bottom part of tank 1.

T3: Temperature sensor in the top part of tank ( for control

auxiliary heating)

T4: Temperature sensor on hot water pipe

P1: Solar circuit pump 1

P2: Hot water circuit pump

Note:

•H1 is connected with auxiliary heating, suitable for

system 1 – 8.

•T3, T4, P2 are suitable for system 1-8

•T3 is alternative, when no sensor (T3) is installed in the

top part of sensor, controller will use the signal of sensor

T2 automatically to control the auxiliary heating.

Description:

If the switch – on temperature difference between the

collector array (T1) and one of the two storage tanks (T2,or

T5) is exceeded, then the appropriate solar circuit pump

(P1) or (P0) is switched on. According to the priority

switching, both storage tanks ( T2, T5) are loaded one after

the other, until either the relevant switch-off temperature

difference between the collector array ( T1) and storage

tank (T2, T5) falls below the threshold, or the maximum

storage temperature is reached.

correct position depending on the storage tank to be

loaded. According to the priority switching, both storage

tanks ( T2, T5) are loaded one after the other, until either

the relevant switch-off temperature difference between the

collector array ( T1) and two storage tanks (T2, T5) falls

below the threshold, or the maximum storage temperature

of T2 or T5 is reached.
