Hot water boiler
The presented hydraulic diagram does not replace the central heating system
design and it can be used for reference purposes only.
The boiler regulator controls the central heating pump and the hot water pump according to the
settings made. A room thermostat can be connected which will decrease the preset boiler
temperature. By means of the external temperature sensor the weather control can be activated,
which will modulate the boiler temperature according the external temperature.
The regulator can be extended with two additional mixing modules (MODULE B-MODULE C),
which enable the control of two mixing zones per module (a total of four mixing zones). Each
mixing module contains a mixer servomotor, a mixer pump, a mixer temperature sensor and a
mixer room thermostat.
