Due to the risk of fire is prohibited to use the controller in explosive gas and dust environment (eg. coal). Regulator should be separated using an appropriate enclosure. The controller is designed for operation in the environment where only dry conductive contaminations may be present (2 degree of contamination according to PN-EN 60730-1).
In addition, the controller may not be used in water condensation conditions and it may not be exposed to water.
The controller is designed for vertical wallmounted installation. External circuit wires are supposed be lead on surface. Mounting hole locations are presented as in the casing.Before opening the unit casing, disconnect power supply. The unit installation must be done at disconnected voltage.
Controller must be installed by qualified and authorized technician in accordance with EN 60335-1 standard.
For how to open the unit casing see the picture below.
Closing the unit casing see the picture below.
Installations regulator on the wall is shown in the picture below.
The controller must be installed in a way that:
The terminals for hazardous voltage: COM, NO, ZLo, ZN, ZLc, PN, PL, L, N.
The terminal’s safe voltage: TP, T1, T2, T3, T4
After turning on outputs: SM_OFF; SM_ON; P, on the terminals ZLo-ZN; ZLc-ZN, PL-PN giving is 230V~ voltage. After turning on output S is closed terminal COM with NO – without giving voltage.
A detailed description of the output S is included in point 12.6.
The regulator is designed to be fed with 230V~, 50Hz voltage. Supply is connected to terminals L, N, PE.
The electrical system should be:
Electric cables external circuits are predicted for the installation of surface-mounted. A concealed external cable outlet should be provided, as well as protection against the wire being pulled out, loosened or strained, using electric cable tray. It is not allowed to leave any cable leads loose, to roll the excess wire or to bend the wires into acute angles.
It is not allowed to roll the excess wire or to leave disconnected cables inside the regulator housing, as it may lead to damage to the controller.
Example how to install the cables using electric cable trays is shown in the figure below.
Use only following sensor types: CT10, CT6-P. The use of other sensors is prohibited. Sensors cables could be extended by a cable with cross-sectional area min. 0,5mm2, a total cable length max. 15m.
Boiler temperature sensor should be installed in thermostatic pipe installed in boiler. Mixer temperature sensor should be installed in sleeve located in stream of running water in pipe, but also it can be installed on the pipe, on condition that it is thermo isolated from the environment.
Sensor must be protected from getting loose from the surfaces to which they are connected. Good thermo contact should be maintained between sensors and measured surface. To this purpose thermoleading paste should be used. It is not acceptable to lubricate sensors with water or oil. Wires of sensors should be separated from network electrical wires. In such a case wrong readings of temperature may be shown. Minimum length between those wires should be 100mm. It is not acceptable to allow for contact betweens wires of the sensors and hot parts of the boiler and heating installation. Wires of the sensors are resistant to temperature not exceeding 100ºC.
From the regulator can also be formed to correct an error reading from temperature sensors: circuit heating, external, return and boiler to the nearest 0,1°C.
The value correction set in: Service settings → Temperature correction
The regulator cooperates only with a weather sensor of the CT6-P type. The sensor should be installed on the coldest wall of the building, usually this is the northern wall, under a roof. The sensor should not be exposed to direct sunlight and rain. The sensor should be fitted at least 2m above the ground, far from windows, chimneys and other heat sources which could disturb the temperature measurement (at least 1,5m).
Connect the sensor using cable of 0,5mm2 cross-section, up to 25m long. Polarity of the leads is insignificant. Connect the other end of the cable to the regulator. Attach the sensor to the wall using tackbolts. To access the tackbolts holes, unscrew the sensor lid.
Temperature sensors CT10, CT6-P can be checked by measuring their resistance in given temperature. In case of big differences between measured resistance value and values in table below, the sensor should be replaced with a new one.

Connecting a room thermostat
Room thermostat (NO-NC) connected to the control affects the heating circuit. The thermostat after contact opening reduces the preset temperature heating circuit about the service value Decrease of thermostat or can turn off the pump in the parameter Off by thermostat. The values of the parameters must be chosen so that when of working the room thermostat (contact opening) the temperature in the room dropped.
Connecting a heat source
COM-NO terminals are used to connect the contact heat source (no voltage) that turns on and off the heat source. The heat source can be automatic boiler gas or oil, which has a contact ON-OFF. Terminals COM-NO does not have galvanic isolation of 230V ~ and can therefore only serve to disconnect circuit voltage of 230V ~. Use separate relay in the event of having to disconnect circuits at low voltage.
Risk of electric shock caused by current from a heat source.Disconnect the controller and heat source electrical supply and make sure there is no dangerous voltage on terminals.
Protect yourself against incidental generation of supply voltage! Connection to heat source (gas or oil boiler) should be done by a qualified installer, according to technical data of this boiler.

Settings for heating circuit without weather sensor.
Should disable the external temperature sensor in the External sensor from the service menu and then It is necessary to manually set the required water temperature in the heating mixer circuit using parameter Preset mixer temp., e.g. at a value of 50°C. The value should allow to obtain the required room temperature. After connecting room thermostat, it is necessary to set a value of decrease in preset temperature by thermostat (parameters Decrease of thermostat) e.g. at 5°C. This value should be selected by trial and error. The room thermostat can be a traditional thermostat (NO-NC). Upon activation of the thermostat, the preset mixer circuit temperature will be decreased, which, if proper decrease value is selected, will stop growth of temperature in the heated room.
Settings for a heating circuit with weather
sensor.
Shouldn’t disable the external temperature sensor in the External sensor from the service menu.
Using the parameter Curve parallel move, set preset room temperature following the formula: Preset room temperature = 20°C + Curve parallel move.
In this setup, it is possible to connect a room thermostat which will equalize the inaccuracy of selecting the heating curve, if the selected heating curve value is too high. In such case, it is necessary to set the value of parameter Decrease by a thermostat, e.g. at 2°C. After opening of the thermostat contacts, the preset mixer circuit temperature will be decreased, which, if proper decrease value is selected, will stop the growth of temperature in the heated room.
Weather control.
For the heating, circuit can be turned on weather control, which requires the connection of external temperature sensors. It should enable the external temperature sensor by setting:
Service settings → External sensor = ON – cause additional menu Weather control.
The heating circuit water preset temperature is calculated basing on the temperature prevailing outside the building. The colder it is outside, the higher water temperature in the heating circuit is. This relation is shown in the controller in the form of heating curve. The heating curve can be changed in a graph from the system menu, within the range for the weather preset temperature. It is a reflection of the thermal characteristics of the building. If the building is less insulated then the heating curve should be greater. Heating curve should be selected experimentally by changing it in a few day intervals. During trialand error selection of appropriate heating curve, it is necessary to exclude influence ofthe room thermostat on regulator operation (regardless of whether the room thermostat is connected or not), by setting the parameter:
Service settings → Room thermostat = OFF.
After choosing the proper heating curve, the circuit preset temperature is calculated according to the outside temperature. As a result if the heating curve is appropriate for the building, the room temperature remains constant regardless of the temperature outside.
The regulator introduced value for the heating curve for underfloor heating:
external | t. | +10 | -> | preset | t. | = | 24 |
external | t. | 0 | -> | preset | t. | = | 28 |
external | t. | -10 | -> | preset | t. | = | 32 |
external | t. | -20 | -> | preset | t. | = | 36v |
and radiators system:
external | t. | +10 | -> | preset | t. | = | 40 |
external | t. | 0 | -> | preset | t. | = | 47 |
external | t. | -10 | -> | preset | t. | = | 55 |
external | t. | -20 | -> | preset | t. | = | 65 |
Guidelines for selecting a proper heating curve:
Poorly warmed buildings require setting higher heating curves. Whereas for well heating buildings, heating curve will have a smaller value.
The regulator can increase or decrease the preset temperature, calculated in accordance with the heating curve, if it exceeds the temperature range for the given circuit set inparameters Min. temperature and Max. temperature.
Frost protection function is applicable only to active controller work modes: OFF or AUTO- ECO. In AUTO-ECO mode, this function is executed only during a night time decrease. The function is activated in the menu: Services settings → Protection → Frost protection
Description of frost protection against the external temperature sensor readings
When the external temperature drops below 3°C, an Frost protection delay, e.g. 4h must expire. If after this time the external temperature is still under 3°C, a heating circuit pump will be activated for 30 minutes. After 30 minutes temperature on the mixer sensor will be checked and if the temperature is lower than 13°C to preset temperature heat source is set to Frost protection temp. value. Turning off the pump and the heat source will take place only after the external temperature rises above 3°C. The pump circuit is also activated when there is a risk of freezing circuit.
Adjustable circuit
When the external temperature drops below 3°C, an Frost protection delay, e.g. 4h must expire. If after that time the external temperature does not rise above 3°C the heating circuit pump will turn on for the duration of 15 minutes. After 15 minutes, water temperature in the circuit will be checked. If it is higher than 13 °C, the pump will be stopped. If it is lower than 13 °C, the pump will continue its operation and heating circuit will be heated by a heat source up to a Frost protection temp. value. The pump will be stopped unless the external temperature exceeds 3°C.
If the heating circuit must be turned on during this period, instead of off the controller must be activated for the heating circuit working mode: OFF or AUTO-ECO.
During a risk of frost, do not connect the controller from the mains supply.
In case of power stoppage the controller returns to operation mode in which it was before stoppage.
The function tries to cool down the heat source before switching the regulator into the alarm state of overheat of the heat source.
The controller performs the function of protecting pump from anti standstill. It involves the periodic switching (which 167h for a few seconds). This protects the pump against immobilization due to scaling. Therefore, during a break in the use of the controller, the controller power supply should be connected.
Cut off power supply to the controller before fuse replacement. Use 1.25A time-delay subminiature fuse with minimum interrupting current of 100A should be used, as per IEC 60127 standard. To replace open controller’s enclosure and replace burnt fuse with a new one.
