Technische Alternative ESR 31 Mode D'emploi page 11

Generally for all programs (16, 17):
No thermostat function or differential switching function is activated. Calling one of these
two programs the measuring speed of the input S2 is automatically increased from AV 1.0 to
AV 0.4 (see in the menu MEN under SENSOR) and the speed control is activated as an
alternative parameter list with the following factory settings(see in the menu MEN under
PSC):
Abs. value control AC..... I 2
Differential control DC.. N12
Event control EC.........
Proportional part PRO.... 3
Minimum speed MIN....... 0
In addition, the set values for the desired hot water temperature (DVA) and the mixing dif-
ference (DVD) is put down in the parameter menu to provide the user with quick access.
For more detailed data related to speed process and stability see: Pump speed control
PSC.
Program 16
(only for speed version ESR31-D)
By using the speed control the heat exchange outlet can be kept permanently at a con-
stant temperature via the ultrafast sensor S2 (non-standard accessory MSP60 or MSP130).
Low stand-by losses may occur. A volume flow switch S3 is not necessary.
Program 17
(only for speed version ESR31-D)
The speed control is only activated, if the volume flow switch S3 (non-standard accessory
STS01DC...) indicates a flow. Very few stand-by losses may occur. When starting, the sys-
tem is a little lazier and a volume flow switch is necessary.
Desired value DVA..... 48 °C
Desired value DVD..... 7.0 K

Integral part INT............ 1
Maximum speed MAX...30
Differential part DIF........ 4
Delay time ALV ............ 0
