the lowest temperature setting of the boiler that can be programmed with
thermostat’s knob.
9.2 Maximum boiler temperature –
this parameter specifies boiler max. program-
med temperature setting which can be programmed with thermostat’s knob. It is also
boiler temperature when central heating pump is engaged to provide protection for
the boiler against overheating.
9.3 Boiler upper hysteresis
– if the controller works in burner minimum power
mode, and boiler temperature increase follows by this programmed setting, the
controller will start burner extinction(shut down).
9.4 Burner power switching hysteresis –
when the programmed boiler water
temperature is obtained the controller is switched to minimum power work mode.
This parameter specifies required water temperature drop so that maximum power
work mode was activated. After switching to maximum power the fuel and air feeding
dose is determined according to burner power modulation.
9.5 Boiler protection hysteresis
– the controller provides for boiler minimum and
maximum temperature by providing control over operation of central heating and do-
mestic water pumps. This parameter specifies hysteresis parameter of boiler limit
temperatures switching off.
9.6 Boiler overheating temperature
– this parameter specifies boiler water
temperature when the controller switches off control and activates boiler overheating
alarm.
9.7 Burner power modulation
– when modulation is switched on it will results in
gradual reduction of fan speed and fuel dose to obtain boiler water temperature
corresponding to the programmed setting.
9.8 Burner power modulation factor
– this parameter specifies degree setting
when the controller will reduce burner power before boiler water temperature is
obtained according to the programmed setting. Burner power is reduced by gradual
reduction of fed fuel dose and fan speed reduction. This parameter is unavailable, if
burner modulation power is off.
The room thermostat.
RK-2006SPGMS was equipped with an input for connecting any room thermostat
with contact output. Contacts of the thermostat is signaled by the appearance of the
thermometer symbol in the index of the thermostat.
CAUTION!
The entrance of the room thermostat is active only during WINTER.
Lights up when the input state is independent of the mode setting.
9.9 Mode of operation of the room thermostat
– this parameter determines the
impact of the entry of the room thermostat to the operation of the controller:
