  • Page 10: Principle Of Operation

    RINCIPLE OF OPERATION The EU-800 PID temperature regulator is intended for wood gasification CH boilers. It controls water circulation pump, DHW pump and additional pump. It may also cooperate with 2 three- or four-way valves, a room regulator, GSM module and Ethernet module.

  • Page 11: Fire-Up/ Extinguishing

    EXTINGUISHING This function enables the user to easily fire up the CH boiler. After the fire is initiated, the user activates automatic fire-up function. Owing to optimum parameters the CH boiler smoothly switches to operation mode with the use of the PID function. When the CH boiler enters the fire-up mode, this option changes to Extinguishing.

  • Page 16: Valve Settings

    ALVE SETTINGS The EU-800 PID controller has a built-in module controlling the mixing valve. It is possible to connect two additional valve- controlling modules. There is a range of parameters allowing the user to adjust the valve operation to the individual needs. Once a valve has been enabled, the display shows an additional menu with valve parameters.
  • Page 17 6.1.1.3 OPENING TIME This parameter defines the time needed for the valve to open from 0% to 100% position. This value should be set in accordance with the specification given on the rating plate of the valve actuator. 6.1.1.4 VALVE TYPE This option enables the user to choose the type of valve to be controlled: •...
  • Page 18 Example: Pre-set CH boiler temperature 55°C Room reg. temp. lower 15°C Minimum pre-set CH boiler temperature 45°C Pre-set CH boiler temperature after pre-set room temperature has 45°C been reached Once the pre-set flat temperature has been reached (signalised by the room regulator), the pre-set CH boiler temperature will be reduced to 45°C, which is only by 10°C although the Room reg.
  • Page 19 6.1.1.6 WEATHER-BASED CONTROL ON/OFF WEATHER- VALVE 1,2 BASED CONTROL Heating curve For the function of weather control to be active, the external sensor mustn't be exposed to sunlight or influenced by weather conditions. After it has been installed and connected, weather-based control function needs to be activated in the controller menu.

  • Page 20: Room Reg Temp Lower

    6.1.1.9 SINGLE STROKE This is a maximum single stroke (opening or closing) that the valve may make during one temperature sampling. If the temperature is close to the pre-set value, the stroke is calculated on the basis of the proportionality coefficient parameter value. The smaller the single stroke, the more precisely the set temperature can be achieved.

  • Page 21: Gsm Module

    MODULE NOTE This type of control is available only after purchasing and connecting an additional controlling module ST-65 which is not included in the standard controller set. If the controller is equipped with additional GSM module, it is necessary to activate it by selecting ON. GSM Module is an optional device which, cooperating with the controller, enables the user remote control of the CH boiler operation via a mobile phone.

    OOM REGULATOR CH pump control FITTER’S CH boiler control ROOM MENU REGULATOR TECH RS regulator (ON/OFF) This function enables the user to select the type of regulator connected to the EU-800 PID controller and configure the room regulator operation.

  • Page 23: Ch Pump Control

    6.6.2 The EU-800 PID is a controller with continuous output signal, using PID control algorithm. This type of controller calculates the fan speed on the basis of CH boiler temperature and the flue gas temperature measured at the CH boiler outlet. The fan operates continuously and the fan blow force depends on the CH boiler temperature, the flue gas temperature as well as the difference between these parameters and their pre-set values.

  • Page 24: Buffer Parameters

    TEST RESULTS - TECH controller with PID control: TEST RESULTS - TECH controller without PID control: All remarks concerning the software should be reported to the CH boiler manufacturer. Each controller should be customized to individual needs, depending on the type of fuel and CH boiler used. TECH does not accept responsibility for incorrect configuration of the controller settings.

  • Page 25: Buffer

    6.7.1 BUFFER Once the buffer function has been activated (by selecting ON), the CH pump serves as pump of the buffer in which two sensors are installed: upper sensor (C1) and lower sensor (C2). The pump remains active until the pre-set parameters are reached. When the temperature drops below the pre-set buffer top temperature, the pump is activated again.

  • Page 26: Additional Heat Source

    6.10 A DDITIONAL HEAT SOURCE This option is available only in Standard operation mode. Using this option the user may enable or disable the additional heat source. 6.11 A DDITIONAL PUMP CH pump CH boiler protection FITTER’S MENU ADDITIONAL PUMP Circulating pump Short circuit pump The user may connect an additional pump.

    6.15 P UMP ANTI STOP When this function is active, the pump is activated at a user-defined frequency (every 1-20 days), for a pre-defined time (minimum: 30 seconds; maximum: 180 seconds). It prevents stagnant water in the heating system outside the heating season. 6.16 A FREEZE TEMPERATURE This function is used to configure anti-freeze option which serves as protection of the heating system against freezing.

  • Page 29: Temperature Alarm

    EMPERATURE ALARM This protection is activated only in operation mode (when the CH boiler temperature is lower than the pre-set temperature value). If the CH boiler temperature does not increase within the period of time defined by the user, an alarm is activated: the fan is disabled and a sound signal is activated.

  • Page 30: Technical Data

    ECHNICAL DATA Before and during the heating season, the EU-800 PID controller should be checked for condition of its cables. The user should also check if the controller is properly mounted and clean it if dusty or dirty. It is advisable to measure earthing parameters for the motors (CH pump, DHW pump and fan).
