General Description

The DQ15D digital temperature control is a p r o -
g r a m m a b l e a n d microprocessor based device
that operates two relays for temperature control.
Features
The temperature sensor (RTD or thermocouple)
sends a signal to the DQ15D to compare to a value
preset by the user as a Set Point (SP). Set Points
LEDs are SP1 and SP2 on the front panel.
• In heating mode if the sensor signal is lower than the
SP1 Set Point value, DQ15D energizes the SP1 relay
and its isolated contacts close.
• In cooling mode if the sensor signal is higher than the
SP2 Set Point value, DQ15D energizes SP2 relay and
its isolated contacts close.
• DQ15D has an optional Alarm Condition feature. After
you activate this feature, when the sensor signal ex-
ceeds the Alarm Set Point, DQ15D goes into an
alarm condition. In an Alarm Condition, both relays
de-energize and the screen displays a flashing AAA.
• The power save, night setback feature permits the use
of a second heating Set Point to conserve energy
when required.
Installation Procedure
DQ15D is for indoor use only.
Unpack and inspect DQ15D for damage upon re-
1
ceipt. Shipping damage claims must be made
through the freight carrier.
Remove rear cover and inspect DQ15D for internal

Remove the Retaining Collar. Insert a flathead
3
screwdriver under the collar on alternating sides
while sliding the collar back.
Cut a 1 / 4 DIN finished opening: 3.625" x 3.625" (92 mm
4
x 92 mm) in the desired mounting panel location.
5 Select one or more knock-outs from the three (3)
knockouts on the rear cover or enclosure side pan-
els that offers the most convenient routing for ex-
ternal wiring.
Avoid damaging circuitry. Remove rear cover be-
fore removing knockouts with a hammer/punch.
Évitez d'endommager les composants du DE20. Enlevez
le panneau arrière avant d'enlever le plastique pour
faire des trous avec un marteau ou un poinçon.
