Zone valve
This feature can control a solar accumulator charging valve. This enables charging of a second tank or second tank zone. The number
on the left next to the zone valve indicates which tank / zone is being charged by the system.
Tmax storage 2
Maximum temperature storage 2. Up to this temperature, store 2 or the 2nd store zone will be charged.
Solar storage 2
In this menu, the storage tank sensor 2 must be set.
Heat exchanger
Adds a heat exchanger and a secondary pump to the solar circuit. Function is only visible if the additional funciton Solar is activated.
Heat exchanger sensor
The sensor that is used to turn on the secondary pump. It must be on the primary side on the heat exchanger.
Burner
This function requests a burner when a request of a heating circuit or the DHW function is present. Depending on the request, the burner
will turn on in a more economic manner in the Eco-Mode if the solar circulation pump is running.
DHW request
The burner is started for a DHW - heat request.
Heating Circuit request
The burner is started for a heating circuit heat request.
Burner sensor
Reference sensor for burner function. If this temperature at the set sensor is exceeded, the burner is shut down.
Delay
Switch delay, valid for cooling and heat request. The burner first turns on after this time span if the switch conditions were reached and
are still present. This feature prevents unnecessary switching by temperature fluctuations or gives time for a renewable energy source to
generate energy.
Burner offset
When using the 0-10V outputs V1 or V2 for the burner function, the requested temperature is emitted through a corresponding voltage.
This offset increases the requested temperature.
Eco mode (during solar charge)
The economy mode for this function can be operated in 2 different variants:
Shutdown: The function is not started with an active solar charge.
Decrease:
For a heating request the function first turns on when the conditions and an additional offset were not met.
For a DHW request the function only activates when Teco is not met and de-activates when Teco + DHW-heating is achieved.
Tmax
Maximum temperature at the burner sensor. If this temperature at the set sensor is exceeded, the burner is shut down.
Enable
(temporal) enable for this function
Here, the desired periods can be set in which the function is enabled.
