[Hot water tank] function block Configuration parameter
It is important that this parameter is checked and
adjusted because if the value is too high, output
regulation of the boiler or buffer, respectively, will be
impaired.
Explanation of [Hot water tank max.]
This parameter defines the maximum temperature of
the hot water tank, and applies to all heat producers -
including solar heating systems - that charge the hot
water tank.
The factory setting is 60°C. This should always
be set 5°C above the target temperature of the
tank.
If the hot water tank is charged by a solar heating
system, you may increase this value.
Explanation of [Sol. chg. until]
Optional: only with solar heating systems
This parameter determines which section of the tank
should be charged up to maximum temperature by the
solar heating system.
If you set it to [Top], the tank is charged until the [Hot
water tank] temperature sensor has reached [Hot
water tank max.].
If you choose the setting [Bottom], charging continues
until the [Hot water tank bottom] temperature sensor
has reached [Hot water tank max.].
Explanation of [Solar heat diss.]
Optional: only for accumulator tanks with solar heating
system
This parameter defines whether the hot water tank
may take excess solar heat from the buffer.
If this parameter is set to [Yes], the hot water tank
takes the solar excess up to the maximum temperature
[Hot water tank max.].
This parameter is factory-set to [No]. You must
check the conditions for the [Extra solar heat]
function in the text menu of the accumulator tank.
Explanation of [Priority]
Optional: only for solar heating systems with
switchover between several tanks
This parameter sets the priority for solar charging of
the hot water tank. A high priority means that this tank
will be charged by the solar heating system first. A low
priority means that it will be charged last.
Explanation of [Circulation runtime]
Optional: Only with circulation pump
This parameter sets the duration for operation of the
circulation pump after it has been started. This period
is only valid inside the set time slot.
After the set period has expired, the circulation
pump is switched off for the configurable duration
of the [Circulation pause] parameter.
Explanation of [Circulation pause]
Optional: Only with circulation pump
This parameter sets the period (pause) after a
circulation pump operating phase. The control system
can only restart the circulation pump after this time has
elapsed. This pause is only valid inside the set time
slot.
Explanation of [Enable circulation]
Optional: only for circulation pump
This parameter defines the minimum temperature of
the hot water tank for starting the circulation pump.
The circulation pump only starts once the hot water
tank has exceeded this temperature.
