Power, Heating And Cooling Relay Wiring; Wire Rtd Sensor Calibration - Process Technology DQ15D Instruction Manual

A small "c" in the lower left-hand corner indicates the control is relying
on default configuration values. This is a rare condition, but may occur
if the control has been calibrated for use with a two-wire RTD sensor but
the configuration parameters have not been changed from their default
values. Changing any of the configuration or set point variables will turn
off this indication.
A large "C" on the left side of the display indicates the control is using the
default values for the configuration and the calibration. This can occur in
a new control that has never been calibrated or configured, or in a control
where the memory has been erased.

Power, Heating & Cooling Relay: Wiring Procedure
Unit is intended for a single power source.
To complete the wiring procedure, you will need these tools and materials:
1. #2 Phillips head screwdriver.
2. 1/8" (x-small) straight blade screwdriver.
3. Power supply wire, 18 awg minimum.
4. Relay connection wires (see state and local electrical requirements
for proper 65º C wire gauge).
Referring to the illustration on page 9, locate and identify terminal loca-
tions for the power supply voltage, the set point relay, and the appropri-
ate sensor. Connect wires into their designated terminals and tighten the
retaining screw which will secure the wire into place.
