circuit ambient temperature
thermostat or sensor
On the Pilot : • The 2
nd
circuit (radiator C-2) or (floor C-2) which must be the same kind as the 1
st
circuit connected to the Pilot, MUST be
activated.
• Activate the ambient temperature thermostat (THERMOSTAT A-2) of the 2
nd
circuit in order to monitor the operation of the
Heat Pump using the on/off alert output of the Thorix Evolution (set parameter
P219 = 1
on the Thorix Evolution).
