EU-391 z PID Principle of operation - operation stages 1. Fire-up This phase starts when the fi re-up function is selected in the controller menu, and lasts until CH temperature reaches at least 400C and the fl ue gas temperature reaches at least 1000C (default fi...
User’s Manual Controller menu VI.a) Block diagram Due to a wide range of functions off ered by the controller, the menu is divided into Main Menu and Fitter’s menu.
EU-391 z PID VI.b) Fire-up (Throttle ON/OFF) The aim of this function is to achieve optimum fl ame in the shortest time possible.The fi re- up eff ectiveness is enhanced by throttle operation. This phase lasts until CH temperature reaches a pre-defi ned value required to enter the operation mode. Once the controller enters operation mode, instead of Fire-up function, Throttle ON/OFF appears in the menu.
User’s Manual VI.e) CH settings CH settings enable the user to activate (or deactivate) voltage-free contact and buff er sensor. If buff er sensor is active (Switching on buff er option selected), the pump is enabled when CH temperature exceeds activation temperature and is higher than buff er temperature by hysteresis value.
EU-391 z PID VI.f) Additional pump settings Additional pump settings enable the user to select the type of additional pump : fl oor pump / DHW pump. The type of pump infl uences the range of temperature settings and protections in case of alarms.
User’s Manual VI.g) Throttle calibration Throttle calibration is performed automatically every few hours (and every time the controller is switched on). This function is used to activate throttle calibration manually. Once this option is selected, the throttle moves slightly above its current position, reaches ‘0’ position and moves back to its original position.
EU-391 z PID VI.k) Factory settings The controller is pre-confi gured for operation. However, the settings should be customized to the user’s needs. Return to factory settings is possible at any time. When the factory settings option is activated, all customized settings of fi...
