Optg mode change CHs+HW : Heating and domestic hot water circuit
changeover mode.
Optg mode changeover HW : Domestic hot water circuit changeover
mode.
Optg mode changeover CHs : The regimes of the heating circuits are
switched to parameter mode on line 900-1200-1500.
Optg mode changeover CH1: The regimes of the heating circuits are
switched to parameter mode on line 900-1200-1500.
Optg mode changeover CH2: The regimes of the heating circuits are
switched to parameter mode on line 900-1200-1500.
Optg mode changeover CH3: The regimes of the heating circuits are
switched to parameter mode on line 900-1200-1500.
Heat generation lock : The generator is locked. All heating circuit and
domestic hot water temperature requirements are ignored. (boiler
frost protection active)
Error/alarm message : The input causes an error message on the
regulator
Consumer request VK1 : The input causes an error message on the
regulator
Consumer request VK2 : The input causes an error message on the
regulator
Release swimpool source htg : Swimming pool requirement
Excess heat discharge : Enables an external generator to force the
switches (heating circuit, DHW, Hx pump) to dissipate any heat sur
plus.
Release swi pool solar : This function enables the release of solar
swimming pool heating by an external resource.
Operating level HW : The temperature level can be adjusted by a
contact (external timer program) rather than by the internal timer pro
gram.
Operating level CH1 : The temperature level can be adjusted by a
contact (external timer program) rather than by the internal timer pro
gram.
Operating level CH2 : The temperature level can be adjusted by a
contact (external timer program) rather than by the internal timer pro
gram.
Operating level CH3 : The temperature level can be adjusted by a
contact (external timer program) rather than by the internal timer pro
gram.
Room thermostat CH1 : This input is used to generate a room tem
perature thermostat demand for heating circuit 1.
Room thermostat CH2: This input is used to generate a room temper
ature thermostat demand for heating circuit 2.
Room thermostat CH3: This input is used to generate a room temper
ature thermostat demand for heating circuit 3.
Hot water flow switch : Connection of the flow rate controller on the
instantaneous water heater.
Hot water thermostat : Connection of the domestic hot water tank
thermostat.
Pulse count : Impulse counter.
Checkb sign flue gas damper : Feedback on flue gas valve position.
Boiler flow switch : Start-up authorisation by flow rate controller.
Boiler pressure switch : Start-up authorisation by pressure switch.
