3.3 Store loading
In this menu, all adjustments for the DHW heating and loading of the secondary
store can be made. The following parameters and functions are available:
• Emergency operation
• Hot water set temperature / Set temperature secondary circuit fl ow
• Minimum hot water set temperature / minimum set temperature secondary
circuit fl ow
• Maximum hot water set temperature / maximum set temperature secondary
circuit fl ow
• Sliding set value
• Blocking protection

The Emergency operation function can be used for ensuring the hot water
supply and loading of the secondary store in the case of a sensor fault. In this case
the pumps will run at the adjustable Em. prim. and Em. sec. For this purpose,
the emergency speed must be aligned with the resulting temperature at the hot
water fl ow sensor in the secondary circuit. The display channel
T-HW allows this
alignment directly in the Store loading menu, as soon as the emergency operation
has been activated.
Note:
If a sensor fault inhibiting DHW heating or store loading has occurred,
activate the emergency operation in the Emergency mode channel.
In order to ensure a quick entry to emergency operation in the case of an emer-
gency, perform the alignment of the emergency speed as early as possible.

This parameter can be used for adjusting the T-HW set temperature which is to
be reached at the HW fl ow sensor. This temperature is also used for loading the
secondary store. The controller then determines the pump speed of the primary
pump such that the temperature at the HW fl ow sensor in the secondary circuit
continuously keeps the required set temperature T-HW set.
Note:
If the SUS Sys 2, 3 variants have been selected and the circulation function
is active, T-HW set cannot be adjusted to a value smaller than (T-circ
on +
∆
T-circ off + hysteresis).
