    RINCIPLE OF OPERATION The ST–801 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 10: 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.

    5.11 S ERVICE MENU In order to access service settings of the EU-801 PID controller, it is necessary to enter a 4-digit code provided by TECH. 5.12 L ANGUAGE This option is used to select the controller language version.

  • Page 14: Controller Functions - Fitter's Menu

    – ’ ONTROLLER FUNCTIONS FITTER S MENU Fitter’s menu is intended to be accessed by a qualified person. It includes additional controller functions such as CH boiler parameters, additional valves, additional pumps as well as advanced settings of basic functions (e.g. parameters of built-in valves).

  • Page 15: Valve Settings

    ALVE SETTINGS The EU-801 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 16 6.1.1.1 VALVE STATUS With this option the user may enable or disable the valve. 6.1.1.2 PRE-SET TEMPERATURE This parameter defines the desired temperature which the valve should maintain. During proper operation, the temperature of water downstream of the valve approaches the pre-set value. 6.1.1.3 OPENING TIME This parameter defines the time needed for the valve to open from 0% to 100% position.
  • Page 17 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 18 6.1.1.6 WEATHER-BASED CONTROL ON/OFF WEATHER- BUILT-IN VALVE, BASED VALVE 1,2 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 19 6.1.1.8 RETURN PROTECTION This function allows setting up CH boiler protection against too cool water returning from the main circulation, which could cause low-temperature boiler corrosion. The return protection involves closing the valve when the temperature is too low, until the short circulation of the boiler reaches the appropriate temperature.

    6.1.1.15 ADDITIONAL SENSORS Option available for valves 1,2. When two mixing valves are used, this function enables the user can select the sensors which will provide temperature data for the valve (for external and return temperature sensors). Temperatures can be read from the sensors of a given valve (own) or the sensors of valve 2 (from module 2).

  • Page 23: Ch Boiler Control

    6.6.2 The EU-801 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.

    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.

    ROTECTIONS In order to ensure safe and failure-free operation, the regulator has been equipped with a range of safeguards. In case of alarm, a sound signal is activated and the display shows an appropriate message. In order for the controller to return to the operation mode, press pulser knob. In the case of CH temperature too high alarm, it is necessary to wait until the temperature drops below the alarm value.

    ECHNICAL DATA Before and during the heating season, the EU-801 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).
