This sensor is used in case to combine Unit with hydraulic separator to detect Hot water
temperature detection of hydraulic separator.
In case of combining Unit with swimming pool, this sensor is used to detect swimming pool
water temperature.
In case of combining Unit with solar panels, this sensor is used to Detect Hot water
temperature of solar panels.
Optional Second Outdoor Ambient Temperature sensor accessory can be connected to the Auxiliary
sensor in case that the heat pump is located in a non-suitable position for this
measurement.
When Water Cycle 2 is available, auxiliary sensor need be configured as function of "Tow2" to detect
outlet water temperature of Water Cycle 2.
Used to detect duty signal when duty signal control is Enabled, the duty signal type can be 0- 10V, 0-5V
or 10-20mA.
Rooms function on master controller is selected as room thermostat, and in this scenario, auxiliary sensor
can be configured as function of "Room_amb1...7", and can be selected as room temperature detection
of specific room.
Auxiliary temperature sensor to detect water temperature in the DHW tank of lower side.
