DIP Switch Settings
Control Settings Outdoor Sensor
An optional Outdoor Sensor may be connected to the
control. If the sensor is required, connect the two wires from
the Outdoor Sensor to the Com (common sensor) and Out
(outdoor sensor) pins. The outdoor sensor is used by the
control to measure the outdoor air temperature.
External Input
The control can accept an external input signal from an
external control. If an external input signal is required,
connect the positive 0-10 V (dc) wire to the +V(in) pin and
connect the negative 0-10 V (dc) wire to the Com/- pin.
CONNECTING THE CONTROL
Make sure all power to the devices and wiring harness
is off.
Reconnect the wiring harness to the connector on the
control by aligning the tab on the wiring harness to the tab
on the connector on the control and then pushing the wiring
harness into the connector on the control. The tab on the
wiring harness should snap over the tab on the connector
of the control.
Apply power to the control. The operation of the control
on power up is described in the Sequence of Operation
section of the brochure.
