When commissioning a plant, the respective plant type must be selected. Three- position control through the mixing valve in the main flow. Heat demand signal from the data bus. No heating program. Manual operation The RVL can be switched to manual operation. In that case, the control will be switched off. Page Plant Type And Operating Mode The operational level is determined by the heating pro- gram and the holiday program.
In that case, the RVL can ascer- tain the average of the two measurements. The other room unit functions will not be affected by averaging 4. Page Secondary Return Temperature B71 If there is a short-circuit or open-circuit in the measuring circuit, and if the controller re- quires the return temperature, DRT limitation will be deactivated and a fault status mes- sage generated. Heating program The heating program of the RVL provides a maximum of three heating periods per day.
Also, every weekday may have different heating periods. Page Function Block "End-User 2 Time of day and date The RVL has a yearly clock to enter the time of day, weekday and date.
The changeover from summer- to wintertime, and vice versa, is automatic. Should the respective regulations change, the changeover dates can be adjusted refer to section " There will be no acknowledgment. Page Function Block "Plant Type All plant-specific variables and operating lines that are available for the other plant types will then be dead.
Example selection of plant type no. Page Function Block "Space Heating This ensures that no heating will be provided in the summer when, under normal cir- cumstances, the heating would be switched on because the outside temperature drops for a few days. Page Fundamentals 8. Page Optimum Stop Control Setpoint of the reduced room temperature 8. Optimization calculates the changeover time such that, at the end of occu- pancy, the room temperature will be 0. Toward the end of the non-occupancy time, optimization switches the control to boost heating.
This means that the selected boost will be added to the room temperature setpoint. Page Parallel Displacement Of Heating Curve — the current flow temperature setpoint is gener- ated. It can be called up on operating line also refer to section " Function block "Service functions and general settings"". Page Generation Of Setpoint Demand-compensated control is used with plant types 4, 5 and 6. In that case, the out- side temperature will not be taken into consideration.
This is a boost of the heating zone's flow temperature setpoint. The higher setpoint is delivered to the heat generating equipment as the heat demand signal. For that purpose, thermostats, thermal reset limit thermostats, etc. Page Minimum Limitation Of The Boiler Return Temperature Actual value of the boiler temperature Burner control signal Note: when controlling a single-stage burner, the reset limit of the second stage should be set to zero. Page Frost Protection For The Boiler When the integral reaches the value of zero, protective boiler startup will be deactivated, in which case the critical locking signal is zero.
Page Protection Against Boiler Overtemperatures Protection against boiler overtemperatures To prevent heat from building up in the boilers protection against overtemperatures , the RVL offers a protective function. When the first burner stage is switched off, the controller allows the boiler pump to over- run for the set pump overrun time operating line on the boiler temperature control- ler , generating at the same time a forced signal to all loads inside the controller on the data bus.
Page Operating Mode Of Pump M1 Circulating pump with deactivation setting 1 : The circulating pump runs when one of the consumers calls for heat.
It is deactivated during protective boiler startup. Gain of locking signal". Page Integral Action Time The stroke assigned to the minimum volumetric flow must be acquired by an auxiliary switch fitted in the actuator and delivered to the RVL When bridging terminals H4— M, the valve will close and the waiting time starts.

Als de toets brandt, zet de regelaar het SWW ter beschikking volgens de instelling van de verwarmingsinstallateur — op de volgende uurprogramma's: o volgens het programma van klok 2 o volgens het verwarmingsprogramma o 24 uur op 24 N kruis het betreffende vakje aan Is uw installatie met een boiler uitgerust, dan kunt u die met handbediening laden door op de toets te blijven drukken tot deze toets knippert.
Dit is niet mogelijk in installaties met elektrische lading van het SWW. De SWW bereiding is onafhankelijk van de toestand van de regelaar Tijdens het vakantiebedrijf het symbool verschijnt op de display is er geen SWW bereiding.
Wanneer de ruimtetemperatuur alleen bij zacht weer of alleen bij koud weer niet juist is, dan moet de stooklijn worden gecorrigeerd.
Dit is op drie manieren mogelijk.
