HEATING MODE OPERATION
CompleteStat should never energize “YO” terminals
in conjunction with “B”, so relay “R2” will never
energize, and neither will Economizer Ventilation
Speed.
“Y1” and “Y2” signals will pass through NC contacts of
relay “R2” contacts, and all heating operations will be
normal.
VENTILATION MODE
The call for ventilation will never be disrupted with this
control circuit. Anytime “A” signal from CompleteStat
is present, the “VENTILATION SPEED” of the vent
package will be energized. “A” Signal from thermostat
will also energize relay “R4” (“Blower Interlock Relay”)
completing a circuit from “R” to “G” through the “NO”
contacts to ensure blower operations on the ventilation
call.
