WARNING: Risk of Electrical Shock
Disconnect each of multiple power supplies before
making electrical connections. More than one
disconnect may be required to completely de-
energize equipment. Contact with components
carrying hazardous voltage can cause electrical
shock and may result in severe personal injury or
death.
IMPORTANT:
To ensure that the output relay
operates as intended, verify that all three of the
jumpers are positioned properly for the application
before powering the A419 control.
IMPORTANT:
The touchpad cannot be
unlocked without a jumper installed across the
P5 jumper pins. Do not discard jumpers in case they
are required in the future. See
Figure 4
and
Figure 5
.
Positioning the Jumpers
The
P5 jumper
position determines if the touchpad is
locked or unlocked.
The
P4 jumper
pin block has two pairs of jumper pins.
The top pair of pins (JUMP1) determines if the control
is set for Heating or Cooling mode. The bottom pair of
pins, (JUMP2) establishes whether Setpoint is at cut-in
or at cutout. See Table 2 and Figure 5.
