0-10V ANALOGUE OUTPUT 1 & OUTPUT 2
These connections are used to regulate external fan speed controllers (supplied
separately). Connect direct to fan speed controllers or via your Merlin panel [0-
10V] terminal if available. Minimum voltage output can be configured in settings
menu from zero to 5 volts.
0-10V output can be driven by the status of current CO
temperature only or by the status of both levels (whichever is greatest).
12-24V (AC or DC) POWER
To power the CO2-X with 12-24v power – this should be supplied to the [12-24V
POWER INPUT] connector (+ / -).
This connection can be either AC or DC.
