8.17 NIGHT DECREASE SETTINGS DESCRIPTION In the controller it is possible to set time periods of silo temperature reduction, heating cycles, hot water silo, and circular pump. Time periods allow setting temperature reduction in given time period – i.e. at night or when user leaves the heated room. Thanks to it preset temperature can be reduced automatically, without loss of heating comfort by reducing fuel consumption. To activate time periods use parameter Night time decrease for given cycle and activate it. Night reductions can be defined separately in working days, Saturdays and Sundays. Pic. 9 Window of time periods choosing. It is needed to set the beginning and the end of given time period and value with which the preset temperature will be reduced. In this example from 00:00 to 06:00 the controller will set preset silo temperature by 3 degrees C. Since 06:00 to 09:00 the controller leaves preset silo temperature at preset level (without reductions).Since 22:00 to 23:59 the controller will reduce preset silo temperature by 3 degrees C. Time period is omitted by setting period reduction for value “0” even if scope of hours is set in it 8.18 Attention: functionality of circular pump is available only after connecting additional module MX.03 Settings are in: Night time decrease→ Circular pump. and Service settings→ CH and HUW settings Settings of time control of circular pump are analogical to settings of night reductions. In defined time periods circular pump is deactivated. In omitted periods the circular pump is switched into position circular operation time 8.19 Pic. 10 Time periods edition. Below sample preset reduction is presented. night temperature CIRCULAR PUMP CONTROL FUEL LEVEL CONFIGURATION Fuel level indicator activating To activate displaying fuel level following parameters are to be set Boiler setting→ fuel level→ alarm level On value bigger than “0”, i.e. 10% Twisting “TOUCH and PLAY” knob in main window fuel level is displayed in main window. Tip: fuel level can also be seen in room panel ecoSTER200/ ecoSTER TOUCH. Attention, defining time periods during one day must be started at 00:00! Pic. 12 Additional window with fuel level view. Pic. 11 Sample of defining time periods. Fuel level indicator service Each time when fuel silo is filled to required level it is necessary to press and keep the knob [about 2 s] in main window.
