Connecting the Probe
Example
1. Install the temperature probe several bends into
the condenser. It can be attached to the U-bend
or placed between the fins in the upper 1/3 of the
condenser (see Page 9 for more information).
Note:
The response of the system can be fine
tuned by repositioning the probe.
2. Connect the two wires from the sensor to the terminal
block where it is marked PROBE S1. If additional probes are necessary for
multiple refrigerant circuits, they may be attached to terminals marked
PROBE S2 and PROBE S3.
Note:
The control will respond to the probe that senses the highest
temperature.
Connections for Air Conditioning Only
1. For non-heat pump applications, the heat pump select jumper must
be in the Default (N.O.) position, and the HP terminals must be left
unconnected.
