1-Terminal Strip TB1
All GCS16 commercial units are equipped with a low volt
age terminal strip (TB1). The strip is used for making up all
indoor thermostat and outdoor unit low voltage control wir
ing connections (see figures 5 and 6). The terminal strip is
located in the burner compartment on the outside panel of
the control box.
2-Transformer T1
All GCS16 series units use a single line voltage to 24VAC
transformer mounted in the control box. The transformer
supplies power to control circuits in the unit. Transformers
are rated at 45VA. 208/230 (P) voltage transformers use
two primary voltage taps as shown in figure 7.

3-Transformer Fuse F1
208/230 (P) voltage transformers are not equipped with in
ternal secondary voltage overcurrent protection. 460 (G)
voltage and 575 (J) voltage transformers are equipped
with an integral fuse connected in series with the blue sec
ondary voltage wire. The fuse may be accessed outside
the transformer and is rated 2.5A for 460 volt units and
3.5A for 575 volt units.
4-Transformer T3
460 (G) and 575 (J) voltage units use a line voltage to
230V autotransformer to power the combustion air blower.
The autotransformer is connected directly to line voltage
and is powered at all times. It has an output rating of 0.5A.
5-Transformer T4
575 (J) voltage units use a line voltage to 460V autotrans
former to power the indoor blower. This autotransformer is
also connected directly to line voltage and is powered at all
times. It has a maximum VA rating of 3.4A.
