[Hot water tank] function block
ETAtouch controller
This parameter defines when charging of the hot water
tank will end. As soon as the additional [Hot water tank
bottom] temperature sensor in the hot water tank
reaches the adjustable [HW bottom off] temperature,
charging of the hot water tank ends.
The parameter can be found under:
9.5.2.3
Solar heat diss.
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.
The parameter can be found under:
9.5.2.4
Priority
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.
The parameter can be found under:
9.5.2.5
Circulation runtime
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.
The parameter can be found under:
9.5.2.6
Circulation pause
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.
The parameter can be found under:
