Heating demand

Heating demand
Standard diagram
Function description
The heating demand starts when the temperature in the cylinder (demand temperature, T.dem.)
falls below the Set demand temperature and stops when the temperature in the lower section of the
cylinder (shutdown temperature, T.off) exceeds the Set shutdown temperature.
If the demand sensor T.dem. is used as a boiler sensor (without T.off), the result is modulating
boiler operation.
An optional maximum temperature can be specified for boiler A (the heat generator).
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Demand temp.
Analogue input signal for the demand temperature
Shutdown temperature
Analogue input signal for the shutdown temperature
Set demand temperature
Analogue value specifying the set demand temperature
Set shutdown temperature
Analogue value specifying the set shutdown temperature
Shortfall
Analogue percentage specifying the shortfall in Eco mode
(see Eco mode)
Generator temperature
Analogue input signal for the temperature of the heat generator
Maximum temp generator
Analogue value specifying the maximum heat generator temperature
Charge once
Digital input signal ON/OFF (pulse): Charging the cylinder even when
the temperature has not fallen below the demand temperature.
Set temperature for charge
once
Minimum temperature for "Charge once"
➢ If you want the set temperatures for demand, shutdown and maximum heat generator
temperature to be user-defined settings (fixed thermostat thresholds), specify User as the
source and enter the required value.
