3.1.8
∆
T-regulation
Please note:
The
switch-on temperature difference must
be at least 1 K higher than the switch-off tempe rature
difference
DT O
:
Switch-on temperature diff.
Adjustment range: 1,0...20,0 K
Factory setting: 6.0
DT F
:
Switch-off temperature diff.
Adjustment range: 0,5 ... 19,5 K
Factory setting 4.0 K
DT S
:
Set temperature difference
Adjustment range: 1,5..30,0 K
Factory setting: 10.0 K
RIS
:
Rise
Adjustment range: 1 ... 20 K
Factory setting: 2 K
This function is a standard differential control. If the switch-
on differential is reached (
DT O
), the pump is operated. The
pump runs at 100% speed for 10 seconds. After this period,
the pump runs at minimum pump speed (nMN = 30 %). If
the temperature difference reaches the adjusted set value
(
DT S
), pump speed will increase by one step (10%). If the
difference increases by 2 K (
RIS)
, pump speed will increase
by 10 % respectively until the maximum pump speed of 100 % is
reached. The response of the controller can be adapted via the
parameter „Rise“. If the temperature difference falls below
the adjusted switch-off temperature difference (
DT F
),
the controller switches off.
3.1.10 Collector-limit temperature
Collector emergency shutdown
If the adjusted collector emergency shutdown temperature
(
EM
) is exceeded, the controller will switch off the solar
pump (R1) in order to protect the system against overheat-
ing (collector emergency shutdown). The factoring setting is
140 °C but it can be changed within the adjustment range of
110 ... 200 °C. If the temperature is exceeded, (flashing) is
shown on the display.
EM
: Collector emergeny
shutdown temperature
Adjustment range: 110 ... 200°C
Factory setting: 140 °C
3.1.9 Maximum store temperature
If the adjusted maximum temperature is exceeded, the store
will no longer be loaded in order to avoid damage caused by
overheating. If the maximum store temperature is exceeded,
(flashing) is shown on the display.
Note:
The controller is equipped with a store emergency
shutdown function, which prevents the store from being
loaded when the store temperature exceeds 95 °C.
S MX
: Maximum store
temperature
Adjustment range: 2 ... 95 °C
Factory setting: 60 °C
