The Controller's Digital Outputs (DOs)
control 24 Vac loads only. The
maximum rating is 12 VA for each DO.
For higher VA requirements, 110 or
220 Vac requirements, separate
transformers used to power the load,
or DC power requirements, use an
interposing 220 V 4-relay module
(TEC Relay Module P/N 540-147).

and a Common (C) terminal. Terminate both
connections of a 24 Vac load directly to the
controller board.
N N N N O O O O T T T T E E E E : : : : The 24 Vac "H" terminal is switched
through a TRIAC to the NO terminations when
the associated DO is energized.
8. If using a pressure mode switch, then follow the
instructions (540-719) included with the switch.
9. After the pressure mode switch is installed, wire
the switch to DO8 and AI3 as described in the
instructions.
10. Plug the Room Temperature Sensor cable into
the RTS port on the controller board. Refer to
Figure 1. Run the cable through knockout.
11. Connect the power trunk as shown in Figure 5.
DO NOT apply power to the controller. Run the
wiring through knockout.
12. Replace the enclosure cover and tighten the
