Relays 1 to 4 are semiconductor relays for pump speed con-
trol of standard pumps. Relative pump speed is adapted in
10 % steps to the current temperature difference between
the collector and the store (see also 4.1 speed control).
In some cases, it is necessary to adapt the factory setting of
the minimum pump speed (30%). If it is set to 100 %, pump
speed control is deactivated (valves).
In the submenu "language", different languages are availabe.
In this menu, individual or all relays can be switched-on
(relay test), switched-off, or set into automatic mode.
Precision-platin sensors PT1000 (FKP and FRP) are used
for the controller ECOTRONIC Plus.
Depending on the individual solar system, the product range
contains 3 different sensor types: sensors with immersion
sleeves, flatscrew sensors and cylindrical clip-on sensors. The
sensor types FK and FR have the same electrical features
and are available in the same models, they only differ in the
connecting cable:
FK: 1,5 m weather- and temperature resistant silicone cable
clip-on sensor
for temperatures between -50 °C ... +180 °C, mostly used
for collectors.
FR: 2,5 m PVC cable for temperatures between
-5 °C ... +80 °C, mostly used for stores.
Note:
In order to avoid overvoltage damage at collector sensors
(e.g. caused by local lightning storms), we recommend in-
stalling the overvoltage protection SP1.
