Figure 2 - Mounting Bracket and Instructions  
Installing the Display  
Safety  
First, it is recommended to remove both AC and DC power from your system. Unplug your RV from  
shore power and turn off any converters or generators to remove AC power. Open your 12-volt DC  
bus breaker or fuse to de-energize your display. This greatly reduces the chance of any harmful  
electrical discharge, as well as preventing accidentally opening a fuse.  
Removing the Old Display’s Faceplate  
SZLCD  
This is the thermostat in Figure 1 that has the square LCD and raised circular plastic. Depress the  
rectangular locking tab on the bottom of the display with a small screw-driver. Pull the front of the  
display away from the wall from the bottom.  
CT  
This is the thermostat in Figure 1 that has the rectangular LCD and has capacitive touch buttons.  
Carefully hold the base of the thermostat at the bottom while pulling the cover plate away from the  
wall. It is easiest to pull at one of the corners to get the plastic to pop off.  
Backplate and Wire Labels  
The backplate is now exposed that shows its screws and the display’s wiring. Before removing the  
wiring, write down the color of the three wires and the name of the terminal that each wire goes to.  
Also take a picture of this wiring for your reference. The wire terminals will be labeled 12V+, COM or  
COMMS, and -12V or GND, depending on which display you have. You can use Table 2 to write down  
the color wire related to the three terminal labels. After recording the original wiring, disconnect  
them from their screw terminals and remove any wall attachment screws. Free the back plate from  
the wall.
