2.6 Terminal allocation with cable link
The controller calculates the temperature difference between collector sensor
S1 and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference (DT O), the solar pump will be activated by
relay 1, and the store will be loaded until the switch-off temperature difference
(DT F) or the maximum store temperature (S MX) is reached.
Sensor S3 is used for a thermostat function, which operates relay 2 for backup
heating purposes, when the adjusted thermostat switch-on temperature (BH O)
is reached. This function can optionally be combined with up to 3 adjustable time
frames.
Sensor S3 can optionally be used as the reference sensor for the thermal disinfec-
tion function (OTD) or the store emergency shutdown option (OSEM).
Sensor S4 can optionally be connected. For heat quantity measurement, S1 and S2,
S1 and VFD or VFD and S4 respectively can be used as ow and return sensors.
