Principle of operation:
The CS-08 controller is intended for the control of central heating and hot water pumps.
The central heating pump switches on when the temperature of the boiler exceeds the temperature set by the user for starting up the central heating pump. The hot water pump works on the principle of temperature differences. The hot water pump is started up when the temperature of the boiler exceeds the temperature of the heat accumulator by the hysteresis set by the user. The hot water pump continues to operate until the temperatures of the boiler and the store equalize, or until the set temperature of the store is reached.
Pzh in operation if Tk ≥ "C", otherwise pump off.
Pp in operation when Tk + H> Tp until Tk = Tp or value "U" is reached
otherwise the pump is off.
Abbreviations
Pzh = central heating pump
Pp = pump buffer (hot water) Tk = temp. Boiler
Tp = Temp. Buffer (hot water)
Adjustable values:
H = hot water pump hysteresis
C = commissioning temperature of the central heating pump,
U = maximum temperature of the buffer (hot water)
P = priority of the hot water pump
L = summer mode (hot water pump only)
Function P (priority) - with this function, the pumps operate in priority mode. First the hot water pump is switched on. The central heating pump is only switched on when the set temperature of the heat accumulator is reached. If this mode is not switched on, the pumps work independently, without the priority for the hot water pump.
Function L (summer mode) - the central heating pump is blocked, only the hot water pump works. The central heating pump is only switched on when the boiler reaches 90 ° C. This function is intended to protect the boiler from overheating.
