External Input (AI1)
Hot/Cold Air Changeover
For hot/cold air changeover on Sequence 1 or 2,
connect a changeover (temperature) sensor to the
AI1 input. The sensor should be a Type III thermistor
(10K ohm @ 77° F), such as a KMC
duct
sensor or
strap-on sensor. (An inter-
nal 10K ohm pullup resistor is provided on AI1.)
Leave sensor off for continuous cold air mode.
Unoccupied/Standby Setback
Contact closure across AI1 and Common initiates the
standby setback offset sequence, which causes the
cooling setpoint to increase and the heating setpoint
(in Sequence 2 or 3) to decrease by the amount of the
setback offset. (This setback does not apply during
the morning warm-up of Sequences 1 and 2.)
