  • Page 12: Fire-Up

    User’s manual V.2. Fire-up This function enables the user to easily fire-up the CH boiler. After initiating the fire manually (preparing the furnace and starting the fire), the user activates automatic fire-up phase in the controller menu. The controller conducts the fire-up process maintaining the blow and gradually feeding fuel. Thanks to optimum parameters, CH boiler smoothly switches to operation mode.

  • Page 13: V.5.F) Pre-Set Room Temperature

    ST-550 zPID V.5.f) Pre-set room temperature Once a room regulator with RS communication has been connected and activated in the controller menu (Fitter’s menu/Room regulator), the user may adjust the pre-set room temperature. V.6. Manual mode For the user's convenience, the regulator offers manual mode function. In this function, each executive device may be activated and deactivated independently of others.

  • Page 14: Operation Modes

    User’s manual V.9. Operation modes V.9.a) House heating When this function is selected, only the house is heated. CH pump is activated when the temperature is above the pump activation threshold (factory setting). Below this temperature value (minus 2 C – hysteresis) the pump is disabled.

    User’s manual VI.1. PID coefficient NOTE This submenu concerns CH boiler operation with PID control and t is available only when zPID control is active. VI.1.a) CH boiler power coefficient CH boiler power coefficient serves to control the feeder and fan operation at the same time. 100% is the default value but it may be adjusted within the range of 50-110%.

  • Page 19: Vi.3.C) Pre-Set Temperature Top

    ST-550 zPID VI.3.c) Pre-set temperature top This function enables the user to define the pre-set temperature for the upper part of the buffer (sensor should be placed in the upper part of the tank). After this value is reached, the pump is disabled (provided that the pre-set buffer temperature bottom has also been reached).

  • Page 21 ST-550 zPID Temperature control This parameter determines the frequency of water temperature measurement (control) behind the CH or DHW valve. If the sensor indicates a change in temperature (deviation from the set value), then the electric valve will open or close by the set stroke, in order to return to the pre-set temperature.
  • Page 22 User’s manual Sensor selection Option available only for valve 1 and valve 2. When two mixing valves are used, this option enables the user to specify which sensors should be used to provide temperature data for the valve (for external temperature sensor and return sensor). The temperature values may be read from the sensors of the selected valve (Own) or valve 2 sensors (module2).
