Extending Wiring
Except when wiring thermocouples,
you can extend the factory supplied
1000 ohm RTD sensor with standard
22awg or larger electrical hookup
wire. The effect of an additional 22
awg sensor wire length on the value
is approximately 1°F for every 65 ft.
Warning
When dealing with THERMO-
COUPLES, you MUST use specific
thermocouple wire when extending
the sensor wire length. Use of
incorrect extension wire can cause
hazardous operating conditions.
Power, Heating/Cooling
Relay Equipment Needed
• #2 Phillips head screwdriver.
• 1/8 (x-small) straight blade
screwdriver.
• Power supply wire, 18 awg min
• Relay connection wires
Procedure
1 DQ15D is intended for a single
power source. Refer to the Power,
Heating and Cooling Relay Wiring
illustration when wiring DQ15D.
2 Locate and identify terminal
locations for the power supply
voltage, Set Point relay, and sensor.
3 Connect wires to the designated
terminals and tighten retaining
screw to secure the wire into place.
See state and local electrical require-
ments for proper 65°C wire gauge.
See the Specifications chart in the
beginning of this manual for Voltage,
Current, Frequency and other DQ15D
Specifications.
