Special functions
6.5.2. - Thermostat
Thermostat is used for time- and temperature controlled additional heating.
Taget temperature at thermostat sensor 1. Below this temperature, additional
heating is switched on, till TH set + hysteresis is reached.
6.5.2.2. - TH TSet
Hysteresis of setpoint temperature.
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.
6.5.2.3. - TH hysteresis
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.
6.5.2.4. - Thermostat
Optional switch off sensor
When T set + hysteresis is exceeded at the optional thermostat sensor 2, the
relay is switched off.
6.5.2.5. - Thermostat 2
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.

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.
