6.6.2. - Thermostat
Thermostat is used for time- and temperature controlled additional heating.
Settings range: On, Off, Inverted
6.6.2.1. - TH Set
Taget temperature at thermostat sensor 1. Below this temperature, additional heating is switched
on, till TH set + hysteresis is reached.
Settings range: 0-100°C / Default setting: 50
6.6.2.2. - TH hysteresis
Hysteresis of setpoint temperature.
Settings range: -20 to +20K / Default setting: 10K
Temperature values which are set too high can lead to scalding or damage to the
system. Scalding protection must be provided by the customer!
Danger!
Caution
In Energy savings mode, different settings may apply, see e.g. T eco.
6.6.2.3. - Thermostat sensor 1
T set is measured with thermostat sensor 1.
When thermostat sensor 2 is connected, the relay switches on when T set is undershot at
thermostat Sensor 1, and switches off when T set + hysteresis at thermostat sensor 2 is
exceeded.
Settings range: S1-S8, VFS1-2, active storage / Default setting: none
6.6.2.4. - Thermostat sensor 2
Optional switch off sensor
When T set + hysteresis is exceeded at the optional thermostat sensor 2, the relay is switched off.
Settings range: S1-S8, VFS1-2, active storage / Default setting: none
6.6.2.5. - T eco
For Energy saving mode
When Energy saving mode is active: During solar charge T eco is used instead of TH set. When
the temperature drops below T eco at thermostat sensor 1, the relay is switched on and heats up
to T eco + hysteresis.
Settings range: 0-100°C / Default setting: 40°C

For Energy saving mode
Loading this storage activates the Energy saving mode
When this storage is charge by solar, additional heating is only switched on when the temperature
is below T eco.
Settings range: (Storage sensors) / Default setting: fi rst storage
