Settings
4.14. - Auxiliary heating
Auxiliary heat function based on time or temperature.
4.14.1. - TH Set
Target temperature at thermostat sensor 1. Below this temperature, auxiliary heating is
switched on, till TH set + hysteresis is reached.
Setting range: 0°C to 100 °C / Default setting: 50°C
Temperature values which are set too high can lead to scalding or dam-
age to the system. Scalding protection must be provided by the customer!
Danger
Hysteresis of setpoint temperature. Setting range: 1 (highest priority) to 3 (lowest priority).
Setting range: -20 K to +20 K / Default setting: 10 K
4.14.3. - Aux. heat source sensor 1
4.14.4. - Aux. heat source sensor 2
TH set is measured with thermostat sensor 1 and compared to T set. When thermostat
sensor 2 is also connected, the relay switches on when T set is undershot at
thermostat sensor 1, and switches off when TH set + hysteresis at thermostat sensor 2
is exceeded.
Optional switch off sensor
When TH set + hysteresis is exceeded at the optional thermostat sensor 2, the relay is
switched off.
4.14.5. - T eco
TH set in Energy saving mode.
Setting range: 0-100 °C / Default setting: 40 °C
4.14.2. - Hysteresis
4.14.6. - 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.
Setting range: ON/OFF / Default setting: OFF
