Dhw Circuit Additionally Controlled By A Globe Valve - Samson TROVIS 5573 Mounting And Operating Instructions

Parameters
Max. DHW temperature*
Hysteresis**
Charging temperature boost***
Lag of storage tank charging pump
* Parameters serve as limitation of the adjustment range for the DHW temperature to be set
at the rotary switch
** Deactivation value T = DHW temperature + hysteresis
*** Charging temperature T = DHW temperature + charging temperature boost

6.1.1 DHW circuit additionally controlled by a globe valve

In system Anl 11.1, the following version with globe valve can be configured instead of the
three-way valve control in the DHW circuit:

Fig. 9 · Schematics of a storage tank system with a globe valve for return flow temperature limitation
Globe valve and temperature sensor VF2 are used exclusively for return flow temperature limi-
tation in the schematics shown above. The pre-control circuit provides at least the same flow
temperature as in the standard schematic version which is calculated from DHW temperature
set point + Charging temperature boost + Boost set point of primary exchanger control.
The functions and parameters of the DHW heating in the storage tank system are upgraded by
the following settings:
