INSTALLING THE DIGITAL THERMOSTAT
(if supplied)
This optional control has several advanced features,
including:
• Touch-pad status indicator for cut-out,
cut-in temperatures
• LED relay status indicator
• Temperature setpoint display
• Programmable setpoint and differential
• Large (.56”) red LED display
Installing this control is fast and simple. When plan-
ning the control location, keep in mind that the sens-
ing bulb wire is 10 feet long.
MOUNTING THE CONTROL HEAD
1. Make the cutout for the control 3.1” x 1.35”
(79mm x 34mm)
2. Snap the control head through the mount
faceplate.
3. Mount the faceplate using the four black screws
provided.
MOUNTING THE TEMPERATURE SENSING
BULB
1. Run the sensing bulb and wire into the refrigerated
box to be controlled. Mount the sensing bulb on a
box side wall midway between top and bottom,
using the two nylon clamps and screws provided.
(NOTE: This is an
air-sensing bulb,
and is not
clamped to the evaporator.)
2. Keep the bulb as far away as possible from the
evaporator (approximately 2 feet away) and out
of the direct airflow if a spillover fan kit is
installed.
3. Secure the excess wire to protect it from chafe and
damage.
CONNECT THE CONTROL HEAD
TO THE CONDENSING UNIT
1. The digital control has a pre-wired power and
signal cable, terminating in a male 4-pin phone
plug. This plug mates with the phone jack (socket)
located on the face of the electrical box on the
condensing unit and marked “T” STAT CONNECTION.
