2.

Carefully push any excess wire back into the wall. 
Seal the hole in the wall with fireproof material to 
prevent drafts from affecting the ambient 
temperature readings.

3.

Reinsert the screw terminal blocks onto the PCB.

4.

Reattach the L

ORKS

 communication wires to 

the LON terminal block. See Figure 5.

Note:

If inserting multiple wires into the terminals, 

be sure to properly twist wires together prior to 
inserting them into the terminal connectors.

5.

Reattach the thermostat cover to the mounting 
base (top side first).

6.

Use a Phillips-head screwdriver to reinstall the 
security screw on the bottom of the thermostat 
cover.
