The Temperature Module (TP) gives the Monitor/controller more
flexibility for the user by being in the same package.
The Temperature Module is driven by the main display output and
is very simple to install.
The Temperature Module and Temperature Sensor SYSTEM
utilize a unique 3 wire technique by which errors are greatly
reduced.
The Temperature Module has its own 0-5VDC output.
TPO kit comes with all items necessary to install and operate: TP
Module; front panel harness with switch, bezel, cap and two o-
rings (006 & 008); and TEMPERATURE label (# LTEMP).
NOTE: Requires the CSXX-TP sensor temperature wires be
routed directly to the TP/TPO CB.

2. INSTALLATION
Briefly -
The Temperature Module replaces the plastic display retainer
plate attached to the front panel.
The display harness plugs into the Temperature Module instead of
the display.
The -TP sensor leads are connected to the Temperature Module.
See figure III.C.1.
The display switch is installed in the lower front panel as shown in
figure III.C.4.
A “TEMPERATURE” label is added to lower front panel next to the
Display Select switch as shown in figure III.C.4.

Physical
If the front panel has all ready been removed from the enclosure
skip to 3.
1. Using a standard slot screwdriver remove the two (2)
screws on the front panel.
2. Carefully wiggle the front panel and pull gently toward
you. Do not pull more than about 8 inches/20CM or you
could damage the wiring harness.
3. Turn the front panel around so that the back side is
facing you.
4. Using a standard slot screwdriver remove the four (4)
screws holding the plastic display retainer plate to the
front panel. When the screws have been removed, the
plastic display retainer plate and the display will be
free from the front panel.
5. Set front panel down or carefully allow to hang from the
harness. Do not drop as the harness connector will pull
out allowing the front panel to fall.
6. While holding the display and the plastic display retainer
plate, carefully remove the display harness connector.
Do not drop the display.
7. Remove and discard the plastic display retainer plate.
8. Insert display connector pins into the Temperature
Module female connector. See figure III.C.1.
