Page 11: Principle Of Operation - Operation Stages
EU-391 z PID Principle of operation - operation stages 1. Fire-up This phase starts when the fire-up function is selected in the controller menu, and lasts until CH temperature reaches at least 400C and the flue gas temperature reaches at least 1000C (default fire-up threshold), provided that the temperature does not drop below these values for 4 minutes (default fire-up time). -

Page 13: Vi.b) Fire-Up (Throttle On/Off)
EU-391 z PID VI.b) Fire-up (Throttle ON/OFF) The aim of this function is to achieve optimum flame in the shortest time possible.The fire- up effectiveness is enhanced by throttle operation. This phase lasts until CH temperature reaches a pre-defined 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. -
Page 14: Vi.e) Ch Settings
User’s Manual VI.e) CH settings CH settings enable the user to activate (or deactivate) voltage-free contact and buffer sensor. If buffer sensor is active (Switching on buffer option selected), the pump is enabled when CH temperature exceeds activation temperature and is higher than buffer temperature by hysteresis value. -
Page 15: Vi.f) Additional Pump Settings
EU-391 z PID VI.f) Additional pump settings Additional pump settings enable the user to select the type of additional pump : floor pump / DHW pump. The type of pump influences the range of temperature settings and protections in case of alarms. In the case of DHW pump, the user may change its activation temperature. -
Page 16: Vi.g) Throttle Calibration
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. -
Page 17: Vi.k) Factory Settings
EU-391 z PID VI.k) Factory settings The controller is pre-configured 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 fireplace controller are lost and replaced with the manufacturer’s settings. - Page 18 User’s Manual VI.l.2) Internet module NOTE This type of control is available only after purchasing and connecting an additional controlling module ST-505 which is not included in the standard controller set. Internet module is a device enabling the user remote control of the CH boiler via the Internet at www. emodul.pl.
