Use 18 AWG copper wire (recommended) for power and connect to terminals XFRM 24 Vac and
.
Use U.L. listed, Class 2 power transformer, 20.4 to 27.6 Vac (24 Vac nominal).
Size the transformer to provide adequate power to the Symbio 210 controller (24 VA maximum)
and outputs (maximum 12 VA for each binary output).
A dedicated 24 Vac, Class 2 transformer is recommended to power the Symbio 210
controller. When powering multiple controllers from one transformer, polarity must
be maintained. Terminal 24 Vac is designated positive (+) and terminal
negative (-) to the unit casing ground. It is important to include power consumption
in the calculations.
The power consumption for cooling-only Series F Models (VariTrac™ and VariTrane™) is up to
26 VA. Refer to Table 5, p. 14
