Analog output 0..10V: geothermal function configured on reverse action
Analog output 0..10V: geothermal function configured on direct action
37 AUXILIARY FUNCTION
37.1 AUXILIARY FUNCTION ON RELAY OUTPUT
The auxiliary relays can be configured to manage two independent, from heat pump or chiller mode, output controls.
Each output can be managed with a dedicated temperature or pressure probe input ( NTC probe, 4..20mA or 0..5V transducers) or with
the common available temperature or pressure configurable inputs.
The probe selection is made with parameters uS02 for the circuit 1 and uS06 for the circuit 2.
The function is enabled when the parameter uS01 <>0 for the circuit 1 and the parameter uS05<>0 for the circuit 2 and at least one
output is configured as auxiliary output.
